How Age Is Calculated for Passport Applications

Your exact age for a passport is calculated by counting the number of complete years elapsed between your date of birth and the date you sign your application. The U.S. Department of State uses three age thresholds that determine passport type, fees, and validity: under 16, 16 to 17, and 18 and older. Getting this calculation wrong can delay or invalidate your application.

The Core Calculation Method

Your passport age is determined by your birthdate relative to the date your application is submitted, not the date the passport is issued or mailed. The U.S. Department of State, the federal agency that issues American passports, counts only fully completed years. A person born on October 15, 2006, who applies on October 14, 2024, is still legally 17 for passport purposes, even though their birthday is one day away.

This distinction matters because passport validity periods, required forms, and applicable fees all hinge on which age bracket you fall into at the exact moment of application submission.

Age calculation also determines which passport acceptance facility (an authorized location such as a post office, library, or county clerk’s office where applications are submitted in person) you must use and whether you qualify for self-service options at all.

Why Three Age Brackets Govern Everything

The State Department divides applicants into distinct age categories that determine the entire application process.

The passport book (the full booklet accepted for all international travel including air entry) and the passport card (a wallet-sized document valid only for land and sea crossings between the U.S., Canada, Mexico, the Caribbean, and Bermuda) follow the same validity rules within each age bracket.

Understanding which bracket you occupy before you gather documents, book appointments, or pay fees saves significant time and prevents the most common application errors.

Calculating Age When Your Birthday Falls Near the Application Date

The single most error-prone situation in passport age calculation occurs when an applicant’s birthday is within days or weeks of their submission date. The rule is straightforward: you must have actually turned the next age, not simply be approaching it.

Consider these three scenarios:

1. Applicant born March 1, 2006, applying February 28, 2024 — Age is 17, not 18. The application requires in-person submission on Form DS-11 and is subject to the rules for applicants who are 16 or 17. The passport issued will be valid for 10 years.
2. Applicant born March 1, 2006, applying March 1, 2024 — Age is 18 on the day of application. This applicant qualifies as an adult, may eventually renew by mail using Form DS-82, and receives a 10-year passport.
3. Applicant born March 1, 2009, applying February 28, 2024 — Age is 14, triggering the under-16 rules requiring in-person appearance of both parents or guardians and producing a passport valid for only 5 years.

Tracking the exact calendar date eliminates guesswork and prevents costly resubmission.

The Documentation That Proves Your Age

Proof of age, meaning the evidence submitted to verify your date of birth to the State Department, must accompany every passport application. The State Department ranks acceptable documents by preference.

Accepted Proof-of-Age Documents

• U.S. birth certificate issued by a state vital records office: the gold standard, listing full name and date of birth with a raised seal or multicolored security stamp.
• Consular Report of Birth Abroad (CRBA), also called Form FS-240: issued to U.S. citizens born outside the country to at least one American parent.
• Naturalization certificate (Form N-550 or N-570): for naturalized citizens, establishing both citizenship and date of birth.
• Certificate of Citizenship (Form N-560): issued to individuals who acquired citizenship through a parent.
• Previous U.S. passport: accepted as proof of citizenship and age if issued within qualifying timeframes.

Key Finding: A hospital-issued souvenir birth certificate is not accepted. Only a certified copy from the issuing state or county vital records office, bearing a raised seal or multicolored security stamp, satisfies the requirement.

When Primary Documents Are Unavailable

Some applicants genuinely cannot produce a birth certificate. This occurs most often for older Americans born at home, born in states or territories with incomplete historical records, or born in countries that have since experienced record destruction.

When a primary document is unavailable, the State Department accepts a combination of secondary evidence that collectively establishes date of birth. Acceptable secondary documents include:

• Baptismal certificate showing date and place of birth.
• Hospital birth record, meaning an actual clinical record rather than a souvenir copy.
• Early census records listing the applicant.
• School records showing date of birth.
• Family bible entries where the birth was recorded contemporaneously.
• Affidavit of birth, which is a sworn statement from an older relative who has personal knowledge of the birth.

The State Department may require more than one secondary document and will evaluate the combination as a whole. Applicants in this situation should contact the National Passport Information Center at 1-877-487-2778 before submitting to understand what specific combination will be accepted.

How Leap Year Birthdays Are Handled

Applicants born on February 29 use their actual birthdate on all passport forms, exactly as it appears on their birth certificate. The State Department does not publish a separate leap-year calculation policy, so acceptance facility agents apply standard completed-year counting from the date on record.

A person born February 29, 2008, who applies on February 28, 2024, has not yet completed their 16th full year under strict calendar counting. Applying on March 1, 2024, places them clearly past that threshold. When the birthday falls on February 29 and the application year is not a leap year, the safest approach is waiting until March 1 to submit, eliminating any possibility of a bracket dispute at the counter.

Age Thresholds and Passport Fees

Fees shift with age brackets, and the State Department adjusts them periodically. The figures below reflect standard rates and should be verified at travel.state.gov before submission, as Congress-authorized fee schedules change.

The execution fee is the charge collected by the acceptance facility for witnessing your signature and reviewing your documents. It is paid directly to the facility, not to the State Department, and is non-refundable even if the application is later rejected.

Optional Fees That Apply Regardless of Age

• Overnight return delivery: approximately $19.53 if you request expedited return shipping.
• Form DS-5504 error correction within one year of issuance: $0 when the error originated on the government’s side.
• Passport photo at the facility: typically $10 to $15 per photo if you do not bring your own compliant image.

Minor Applicants: When Both Parents Must Appear

Children under 16 must apply in person at a passport acceptance facility, and both parents or legal guardians are generally required to appear and sign Form DS-11 simultaneously. This requirement, grounded in the International Parental Kidnapping Crime Act and related federal statutes, prevents one parent from obtaining a travel document without the other’s knowledge.

Exceptions to the Two-Parent Appearance Rule

When one parent cannot appear in person, several alternatives exist:

1. Notarized Form DS-3053 (Statement of Consent): The absent parent completes and notarizes this form, explicitly consenting to the passport application. The form must be signed no more than 3 months before the application date.
2. Sole legal custody documentation: A parent with sole custody presents a court decree, adoption decree, or similar legal order establishing custody. The document must specifically address custody, not merely visitation.
3. Death certificate: If one parent is deceased, the surviving parent presents the death certificate in lieu of consent.
4. Unobtainable consent via Form DS-5525: If the whereabouts of one parent are genuinely unknown and contact is impossible, the applying parent submits Form DS-5525 (Statement of Exigent/Special Family Circumstances). The State Department evaluates these cases individually.

Applicants who are 16 or 17 are treated differently. They may apply with only one parent or guardian present, though the minor must still appear in person and cannot apply by mail.

What Minors Must Bring to the Appointment

• Completed Form DS-11, which must not be signed before appearing at the facility because the signature must be witnessed by the acceptance agent.
• Proof of U.S. citizenship, typically the birth certificate or CRBA.
• Proof of parental relationship, usually the birth certificate listing both parents.
• Government-issued photo ID for the parent or guardian who is present.
• Two passport photos meeting State Department specifications: 2 inches by 2 inches, color, plain white or off-white background, taken within the last 6 months.
• Application fee payment in an accepted form.

Passport Photos and Age-Specific Requirements

Passport photo requirements apply to all applicants regardless of age, but the practical challenges differ significantly for infants and very young children.

Standard photo requirements for all ages:

• 2 inches by 2 inches in size.
• Color photograph on a plain white or off-white background.
• Taken within the last 6 months.
• Head centered, facing directly forward.
• Neutral expression or natural smile with mouth closed.
• No hats, head coverings (except for documented religious reasons), or uniforms.
• Glasses are not permitted in passport photos as of November 1, 2016.

For infants and children under 2:

• Eyes must be open, though the State Department acknowledges this is difficult and makes allowance for photos where eyes are partially open.
• No other people visible in the photo, meaning a parent’s hand supporting the baby must not appear.
• The child may be photographed lying on a plain white sheet, which serves as the background.
• Car seats are not permitted as the background.

For applicants who wear religious head coverings:

• A signed statement must accompany the photo confirming the covering is worn daily for religious reasons.
• The face must remain fully visible from the bottom of the chin to the top of the forehead.

Renewing Before or After Turning 18: What Changes

The rules governing renewal shift entirely once an applicant turns 18, making this the most consequential age threshold in the passport system.

Input your date of birth and today’s date to find your current age. You can also input a different end date to see what your age would be on that day.

Before turning 18:

• Must use Form DS-11 regardless of whether a previous passport exists.
• Must appear in person at a passport acceptance facility.
• Cannot use the mail-in renewal process via Form DS-82.
• Passport issued expires in 5 years if under 16, or 10 years if 16 or 17.

After turning 18:

• May renew by mail with Form DS-82 if the most recent passport was issued at age 16 or older, is less than 15 years old, is undamaged, is submitted with the application, and was issued in the applicant’s current legal name or a name-change document is included.
• Passport issued will be valid for 10 years.

A 17-year-old who needs to travel in six months should apply immediately rather than waiting to turn 18, because the mail renewal option only becomes available after the applicant is already an adult who holds a qualifying prior passport.

The 15-Year Renewal Window for Adults

Adults renewing by mail must confirm their most recent passport was issued fewer than 15 years ago. A passport issued more than 15 years ago means the applicant must appear in person using Form DS-11 and is treated as a first-time adult applicant. This rule catches many long-lapsed travelers who assume their old passport is simply expired rather than ineligible for mail renewal.

Emergency and Expedited Applications: Age Rules Still Apply

Expedited processing does not alter how age is calculated or which age bracket applies. The same birthdate-to-submission-date counting method governs urgent applications identically to routine ones.

Processing Time Comparison by Type

Processing times fluctuate significantly with seasonal demand, particularly between March and August when the State Department processes its highest annual application volume. Checking current posted processing times at travel.state.gov before applying provides the most accurate estimate.

For life-or-death emergencies requiring international travel within 72 hours, applicants can schedule an appointment at one of the 26 regional passport agencies across the United States. Age-bracket rules for fees, forms, and parental consent remain fully in effect even in emergency scenarios.

Scheduling a Regional Passport Agency Appointment

Regional passport agency appointments are not walk-in services. Appointments must be booked through the National Passport Information Center online scheduling system or by phone at 1-877-487-2778. For emergency appointments, the applicant must demonstrate:

• Proof of international travel departing within 72 hours for life-or-death emergencies, or within 5 business days for urgent non-emergency appointments at regional agencies.
• Supporting documentation for the emergency if claiming life-or-death status.

Minors requesting emergency passports must still comply with all parental consent requirements. The urgency of travel does not waive the two-parent consent rule for children under 16.

Name Discrepancies That Complicate Age Verification

A name discrepancy between proof-of-age documents and identity documents will halt a passport application regardless of whether the age itself is correctly calculated. Name mismatches are among the top reasons applications are delayed at acceptance facilities, and they intersect with age verification because the birth certificate, which is the primary age document, is also the most common source of discrepancies.

Common name discrepancy situations include:

• Hyphenated versus unhyphenated surnames: A birth certificate reading “Garcia-Lopez” and a driver’s license reading “Garcia Lopez” create a mismatch requiring a sworn affidavit or legal documentation to resolve.
• Nickname usage: A birth certificate listing “William” while all other documents use “Bill” requires explanation at submission.
• Name changes through marriage or divorce: A marriage certificate or court order must bridge the gap between the birth certificate and current identification.
• Adoptee name changes: Adopted individuals whose birth name differs from their current legal name must provide adoption paperwork alongside proof of age.

Reviewing all documents for name consistency before attending the appointment prevents unnecessary delays that could push travel dates.

Common Age Calculation Mistakes That Delay Applications

The following errors appear regularly at acceptance facilities and cause processing delays or outright rejections.

How Age Affects Passport Validity and Long-Term Travel Planning

Passport validity of 10 years for adults versus 5 years for children under 16 has meaningful practical consequences for families planning extended travel or living abroad. A child issued a passport at age 10 will hold a document valid only until age 15.

Many countries require that a traveler’s passport be valid for at least 6 months beyond the intended stay. This requirement, commonly called the six-month passport validity rule, means a child’s passport may effectively be unusable for international travel well before its printed expiration date.

Building a Family Passport Validity Timeline

Building this timeline before booking international travel prevents last-minute scrambles at the worst possible times.

Countries With Stricter Validity Requirements

Some destinations require more than the standard six months of remaining passport validity. Notable examples for U.S. travelers include:

• Most of Europe (Schengen Area): Passport must be valid for at least 3 months beyond the planned departure date from the Schengen zone.
• Many countries in Asia, Africa, and South America: Require 6 months of validity beyond the stay.
• Some Gulf states: Require 6 months of validity plus evidence of a return ticket.

Checking the specific entry requirements for every destination through the State Department’s country information pages at travel.state.gov is the definitive step before any international trip.

State-Specific Nuances That Affect Proof of Age

Birth certificates are issued by the 50 states, the District of Columbia, and the five U.S. territories: Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands. Each jurisdiction has its own vital records system, and historical records in some territories were affected by natural disasters or administrative changes.

Puerto Rico Birth Certificates

Puerto Rico invalidated all previously issued birth certificates on July 1, 2010, requiring residents to obtain new certified copies through the Puerto Rico Vital Statistics Registry. An applicant presenting a pre-2010 Puerto Rico birth certificate at a passport acceptance facility will find it rejected regardless of their age. New certified copies can be ordered through the Puerto Rico Department of Health’s vital records portal.

American Samoa and Nationals Versus Citizens

Persons born in American Samoa are U.S. nationals, meaning they owe permanent allegiance to the United States, but are not automatically U.S. citizens. U.S. nationals may obtain a U.S. passport, but the document is annotated differently and the applicant must demonstrate national status rather than citizenship. The age calculation for passport purposes works identically to the standard process, but the proof-of-status documents differ from standard birth certificates.

Home Births and Late Registrations

Americans born at home, particularly in earlier decades, sometimes lack a birth certificate or have a delayed registration, meaning a birth certificate filed months or years after the birth rather than at the time of the event. The State Department accepts delayed registration birth certificates, but acceptance facility agents may scrutinize them more carefully. Applicants with delayed registrations are encouraged to bring additional secondary evidence to support the stated date of birth.

How International Adoption Affects Age Documentation

Children adopted internationally and brought to the United States by American citizen parents may have birth documents from the country of birth, and those documents establish the child’s date of birth for U.S. passport purposes.

The relevant proof-of-age documents for an internationally adopted child typically include:

• The foreign birth certificate translated into English by a certified translator if not already in English.
• The IH-3 or IR-3 visa, which is the immigrant visa issued to the child that automatically confers U.S. citizenship if the child was under 18 when admitted and the adoption was finalized.
• The Certificate of Citizenship (Form N-560), which U.S. Citizenship and Immigration Services issues automatically to eligible children or upon application.

If the child’s exact date of birth is unknown, which occurs with some abandoned children whose early records are incomplete, the court that finalized the adoption typically assigns an approximate date. That court-assigned date is then used for all U.S. passport age calculations.

Dual Nationals and Age Calculation Across Multiple Passports

The U.S. Department of State calculates passport age exclusively from the date of birth established by U.S. documentation, regardless of what another country’s passport states. Some U.S. citizens hold citizenship in another country and carry both passports, and discrepancies between U.S. and foreign birth records occasionally occur, particularly when a child was born abroad and different countries recorded slightly different dates due to time zone differences at birth or clerical errors.

When a discrepancy exists, the U.S. passport application should reflect the date on the U.S. documentation, such as a CRBA or a court-ordered determination, and any inconsistency with a foreign passport should be documented with a written explanation submitted alongside the application.

Dual nationality does not extend or alter a U.S. passport’s validity period. A U.S. citizen who is 14 at the time of application receives a 5-year U.S. passport regardless of what validity period another country’s passport provides.

Applying for a Passport After a Long Gap: Age Recalculation

Many Americans hold expired passports from childhood or young adulthood and incorrectly assume the renewal process is simple regardless of how much time has passed. Eligibility for mail renewal depends entirely on how old the expired passport is and what age the applicant was when it was issued.

Key scenarios:

1. Adult with a passport issued at age 17, now expired for 3 years: Age at issuance was 16 or older, the passport is less than 15 years old, and the applicant is now an adult. Mail renewal via Form DS-82 is available.
2. Adult with a passport issued at age 12, now expired for 20 years: Age at issuance was under 16 and the passport is more than 15 years old. This applicant must appear in person with Form DS-11 and is treated as a first-time adult applicant.
3. Adult with a passport issued at age 16, now expired for 16 years: The passport is more than 15 years old. In-person application with Form DS-11 is required even though the passport was issued in adulthood.
4. Adult with a valid passport issued at age 20, not yet expired: Standard adult renewal rules apply when it eventually expires.

The 15-year window is non-negotiable. No exceptions exist for applicants whose passports narrowly exceed the threshold.

Correcting Age Errors on an Already-Issued Passport

If the State Department issues a passport with an incorrect date of birth due to a government data entry error, the applicant can request a correction at no charge using Form DS-5504 within 1 year of the passport’s issue date. The incorrect passport must be returned with the form.

If the error originated with the applicant, meaning the applicant entered an incorrect birthdate on the application, the correction is treated as an amendment and a new full application fee applies. The applicant must reapply using Form DS-11 in person.

Errors discovered more than 1 year after issuance require a full new application with applicable fees, even if the error was the government’s fault at the time of original processing.

The Intersection of Age and Social Security Number Requirements

Form DS-11 requires applicants to provide their Social Security number (SSN), the nine-digit identifier assigned by the Social Security Administration to U.S. citizens and eligible residents. For minor applicants, this means parents must know and provide their child’s SSN. Children typically receive SSNs shortly after birth when parents request one through the hospital’s administrative process or apply directly through the Social Security Administration.

If a child does not have an SSN, which occasionally occurs for children born abroad or adopted internationally before receiving one, the applicant must submit a signed statement explaining the absence. Deliberately providing a false SSN on a passport application is a federal offense under 22 U.S.C. 2714 and can result in denial or revocation of passport privileges.

What “Application Date” Means for Online Pre-Enrollment Systems

The State Department allows applicants to pre-fill Form DS-11 electronically through the Online Passport Application system before appearing in person. In this context, the application date that governs age calculation is the date the form is signed in person at the acceptance facility, not the date the online form was started or submitted electronically.

An applicant who fills out the online form on their birthday eve but does not attend their appointment until two days later is the age they are on the appointment date. Pre-filling the form does not lock in an age or a date for bracket determination purposes.

FAQs

How is age calculated for a U.S. passport application?

Age is calculated by counting the number of complete years between your date of birth and the date you sign and submit your passport application in person. The U.S. Department of State uses this submission date, not the processing date or the date the passport is mailed, to determine which age bracket applies to your application.

What age do you have to be to get a 10-year passport?

You must be 16 years of age or older at the time you submit your application to receive a passport valid for 10 years. Applicants who are under 16 receive a passport valid for only 5 years, regardless of whether they are applying for a passport book or a passport card.

Can a child apply for a passport without both parents present?

Children under 16 generally require both parents or legal guardians to appear in person. If one parent cannot be present, that parent must provide a notarized Form DS-3053 (Statement of Consent) signed no more than 3 months before the application date. A parent with sole legal custody can present a qualifying court order in place of the absent parent’s consent.

Does my age on the application date or the passport issue date determine my bracket?

Your age on the application submission date, specifically the day you sign Form DS-11 or DS-82 in front of an acceptance agent, determines your bracket. The date the passport is printed or mailed back to you is not used for this purpose.

What happens if my birthday falls one day after I submit my passport application?

If you submit your application one day before your birthday, the age you are on that submission date governs your entire application. Submitting one day before turning 18, for example, means your application is processed under the rules for a 17-year-old, including in-person requirements and applicable parental considerations.

How do I calculate my child’s exact age for a passport if they were born on a leap day?

List the exact date shown on the birth certificate, February 29, on the application form. Acceptance facility agents count completed years from that date. If your child was born February 29, 2008, the safest approach in non-leap years is to wait until March 1 to submit, ensuring the full year is unambiguously completed before the application is signed.

What is the passport execution fee, and does it change by age?

The execution fee is the charge an authorized acceptance facility collects for witnessing your application signature and reviewing your documents. It is currently $35 and applies to all applicants regardless of age. It is paid to the facility, not the State Department, and is non-refundable even if the application is rejected or withdrawn.

Can a 17-year-old renew a passport by mail?

No. Applicants who are 17 or younger must apply in person at a passport acceptance facility using Form DS-11. Mail-in renewal using Form DS-82 is available only to applicants who are 18 or older and meet all other eligibility criteria, including that their most recent passport was issued at age 16 or older and is less than 15 years old.

How much does a minor’s passport cost compared to an adult’s?

Minor applicants under 16 pay an application fee of approximately $100 for a book plus the $35 execution fee, totaling approximately $135. Adult applicants 16 and older pay approximately $130 for a book plus the $35 execution fee, totaling approximately $165. Fees are subject to change and should be confirmed at travel.state.gov before applying.

What documents prove my age for a passport?

Accepted proof-of-age documents include a certified U.S. birth certificate from a state vital records office, a Consular Report of Birth Abroad (Form FS-240), a naturalization certificate (Form N-550 or N-570), a Certificate of Citizenship (Form N-560), or a previous U.S. passport. Hospital-issued souvenir birth certificates and photocopies are not accepted.

Does expedited passport processing change the age rules or fees?

No. Expedited processing costs an additional $60 but does not alter how your age is calculated, which forms are required, or what parental consent rules apply. All age-bracket rules remain fully in effect for expedited applications, including the in-person requirement for all minors.

If my child turns 16 while their passport application is being processed, do they get a 10-year passport?

No. The passport validity period is determined by the applicant’s age on the application submission date, not the issue date. If your child was 15 when the application was submitted, they receive a 5-year passport even if they turn 16 during processing.

How far in advance should I account for the six-month passport validity rule when planning travel?

Many countries require your passport to remain valid for at least 6 months beyond your planned departure date. For minor applicants with 5-year passports, subtract 6 months from the printed expiration date to find the last practical travel date. Families should build a passport expiration timeline for all members before booking any international travel.

What is Form DS-11, and who has to use it?

Form DS-11 is the standard U.S. passport application form used by first-time applicants and anyone ineligible for mail-in renewal. All applicants under 18 must use this form and appear in person at an authorized passport acceptance facility, regardless of whether they previously held a passport. The form must not be signed before the in-person appointment because the signature must be witnessed by the acceptance agent.

What is Form DS-82, and what age do you need to be to use it?

Form DS-82 is the U.S. passport renewal application for mail-in submissions. To use it, you must be 18 or older, your most recent passport must have been issued when you were 16 or older, the passport must be less than 15 years old, it must be undamaged, it must be included with your application, and it must be in your current legal name or accompanied by a name-change document.

What happens if the date of birth on my passport application does not match my birth certificate?

The application will be flagged and likely rejected or held at the acceptance facility until the discrepancy is resolved. You must present additional documentation explaining the difference, such as a court order correcting a birth record, a legal amendment, or an affidavit from a parent. Submitting an application with a known discrepancy without addressing it in advance will result in delays or rejection.

Can an internationally adopted child’s foreign birth certificate be used to prove age for a U.S. passport?

Yes. A foreign birth certificate translated into English by a certified translator is accepted as proof of age for internationally adopted children. The child’s IH-3 or IR-3 immigrant visa or a Certificate of Citizenship (Form N-560) also serves as supporting documentation establishing both citizenship and date of birth for passport purposes.

Does the age printed on an existing foreign passport affect how the U.S. calculates passport age?

No. The U.S. Department of State calculates age from the date of birth established by U.S. documentation, such as a CRBA or a U.S. court order. A discrepancy between a U.S. and a foreign passport should be explained in writing alongside the application, but the U.S. documentation controls the U.S. passport age determination entirely.

What if I filled out the online passport pre-enrollment form the day before my birthday but attend my appointment the day after?

Your age for passport purposes is determined by the date you sign the form in person at the acceptance facility, not the date you filled out the online version. Attending your appointment the day after your birthday means you are the older age for all application purposes, including fees, forms, and validity period.

Can a passport be corrected if the wrong date of birth was printed due to a government data entry error?

Yes. If the State Department made the error, you can request a free correction using Form DS-5504 within 1 year of the passport’s issue date. Submit the form with your incorrect passport and documentation showing the correct birthdate. If the error was yours, a new full-fee application is required regardless of when the error is discovered.

What is the National Passport Information Center and how can it help with age-related questions?

The National Passport Information Center is the State Department’s dedicated customer service line for passport applicants, reachable at 1-877-487-2778. It can clarify which age bracket applies to a specific application, advise on what documents are needed when primary proof-of-age records are unavailable, and help schedule appointments at regional passport agencies for urgent situations.
