The passport biographic page is the identity page inside your passport booklet. It holds your photo, your personal details, your passport number, and a strip of machine-readable characters that border officers and scanners use to confirm who you are. In a standard U.S. passport book, it sits as the first or second page inside the front cover and is built from tougher material than the visa pages behind it.
What Is Printed on the Page
The page shows your full legal name, date of birth, place of birth, sex, and nationality. It also carries the unique passport number, the date the passport was issued, and the expiration date. A digitized photograph of you appears on the page, along with the name of the issuing authority. For U.S. passports issued to adults 16 and older, the expiration date is 10 years from the issue date; passports issued to children under 16 expire after five years.
The sex field currently displays either M or F. Following Executive Order 14168 in January 2025, the State Department stopped issuing passports with an X gender marker and now only issues passports with a sex marker matching the holder’s biological sex at birth.1U.S. Department of State. Sex Marker in Passports Applications requesting a different marker may face delays and will produce a passport reflecting sex at birth based on supporting documents.
The Machine-Readable Zone at the Bottom
The bottom of the page holds the Machine-Readable Zone, or MRZ. On a standard passport, it is two lines of 44 characters, printed in a font called OCR-B that automated scanners read instantly.2International Civil Aviation Organization (ICAO). ICAO Doc 9303 Part 1 The encoded data duplicates the printed information: name, passport number, nationality, date of birth, sex, and expiration date.
Tucked inside the MRZ are check digits, single numbers calculated from the characters in each data field. If even one character has been altered or misread, the check digit will not match and the system flags the discrepancy. This catches both scanning errors and tampering without querying any external database. A forger who changes a visible field would also have to recalculate the corresponding check digit, and any mistake in that math exposes the alteration.
Security Features That Make the Page Hard to Forge
The biographic page is engineered to resist forgery. Modern U.S. passports, including the next-generation book introduced in 2021, use a polycarbonate data page with laser-engraved personal details that penetrate the card layers rather than sitting on the surface. Scraping off or chemically altering the information becomes extremely difficult.
Several other layers of protection sit on the page itself:
- Optically variable devices, commonly called holograms, integrated into the laminate and shifting in appearance with the viewing angle.3legislation.gov.uk. ANNEX – Minimum Security Standards of Passports and Travel Documents Issued by the Member States
- UV-fluorescent ink, including the document number, visible only under ultraviolet light.
- Microprinting, tiny text that looks like a thin line but reveals words under magnification.
- Watermarks embedded in paper-based pages during manufacturing, visible against the light.
- A ghost image, a smaller secondary version of your photograph elsewhere on the page, which makes photo substitution obvious.
The ePassport Chip
Most passports issued today are ePassports, marked by a small rectangular chip symbol on the front cover. The embedded contactless chip stores the same information printed on the biographic page, plus a digital version of your photograph as a biometric.4Homeland Security. e-Passports When an officer taps your passport on a reader, the system checks the chip data against the printed page and can run the digital photo against your face.
When Damage to the Page Invalidates the Passport
Not every scuff means your passport is unusable. The State Department distinguishes normal wear from damage. A booklet that has curved from a back pocket or fanned from heavy visa use is still valid.5U.S. Department of State. Frequently Asked Questions about Passport Services
You need a new passport if the biographic page has:
- Water damage: wrinkled, swollen, or curling pages, or ink that has bled and blurred your details.
- A significant tear that compromises the page or the laminate over your photo and data.
- Unofficial markings such as stickers, stamps, or pen marks not placed by an official authority.
- A hole punch or missing pages, sometimes caused by another agency canceling old documents.
Do not try to fix damage yourself with tape, glue, or staples. Any DIY repair counts as tampering and makes the passport legally invalid. If you are unsure whether the damage is serious enough, replace it. An airline or border agent who has doubts can refuse to let you board or enter.
Fixing Errors on the Biographic Page
If the passport arrives with a mistake made by the issuing authority, such as a misspelled name, wrong birthplace, missing data, or crooked printing, you can get it fixed at no charge. The State Department corrects errors by issuing a new passport rather than amending the existing one.6Travel.State.Gov. Change or Correct a Passport
Mail Form DS-5504 with your current passport, one color photo, and evidence of the error, such as a birth certificate showing the correct spelling. There is no fee. If you report the error within one year of the issue date, your corrected passport carries a full 10-year validity period. Report it later and the replacement is valid only through the original expiration date.6Travel.State.Gov. Change or Correct a Passport That one-year window matters, so check the page carefully the day your passport arrives.
A legal name change from marriage, divorce, or a court order also requires a new passport rather than a page amendment. If both the passport was issued and the name changed within the past year, you can use DS-5504 with your name-change document at no fee. Past that window, you apply as a renewal or a new application, with standard fees.
Protecting the Information on the Page
Hotels, visa agencies, tour operators, and car rental desks abroad routinely ask for a photocopy or scan of the biographic page. That single page carries enough information for identity fraud if it lands in the wrong hands: full name, date of birth, nationality, photo, and passport number.
Keep digital scans in an encrypted folder or a password-protected app rather than loose in your camera roll or email. When a business asks for a copy, ask whether a redacted version with the passport number partially obscured will do; many hotels only need to confirm name and nationality. If you carry a backup scan while traveling, store it separately from the physical passport so losing one does not mean losing both.
