To verify a U.S. passport, you check three things in order: that the physical document is genuine, that its electronic data matches and is signed by the issuing government, and that the passport hasn’t expired or been canceled. Knowing how to verify a passport matters because a document that looks real can still be invalid, and a valid document isn’t always accepted for every purpose. The tools available to you depend on who you are — a border officer has database access a hiring manager doesn’t — but the underlying checks are the same.
Inspect the Physical Document
Start with the biographical data page. On a next-generation U.S. passport, issued since 2021, the data page is polycarbonate with laser-engraved information rather than ink printed under laminate.1Travel.State.Gov. Information About the Next Generation U.S. Passport It should feel rigid and smooth, and the text should sit within the page rather than on its surface. Older laminated pages should show no bubbling, peeling, or evidence the laminate was lifted and put back.
Hold the book to a light source. Genuine passports carry watermarks woven into the paper. Tilt the data page and watch for holographic elements that shift in color and depth. Under magnification you’ll see microprinting that reads as a thin line to the naked eye. These are difficult to reproduce with consumer equipment, which is why they remain useful checks.
Several other features are worth looking at:
- Under UV light, a real passport shows fluorescent fibers, images, or patterns invisible in normal light.
- A ghost image — a smaller, fainter copy of the holder’s photograph — should appear on the data page or an adjacent page.
- Perforations punched through multiple pages should form a consistent pattern or spell out the passport number.
- Some printed text should feel slightly raised to the touch.
Then look for tampering. Mismatched fonts, pages that feel thicker than others, glue residue, smeared ink, or biographical details that appear pasted or re-typed are all red flags. Compare the printed name, birth date, and passport number against the Machine Readable Zone at the bottom of the data page. Any mismatch between the printed data and the MRZ points to alteration.2Federal Register. Card Format Passport; Changes to Passport Fee Schedule
Run the Electronic Checks
Physical inspection catches obvious problems. Electronic verification catches the sophisticated ones.
MRZ Scanning
A dedicated passport reader, or certain mobile apps, will scan the two-line MRZ and decode the biographical data instantly. The scanner then compares the decoded fields against what’s printed above. If the MRZ encodes a different birth date, name, or passport number than the printed page, the document has been altered. This is the fastest electronic check and the one most organizations run first.
Reading the Chip
Modern U.S. passport books contain an embedded chip in the front cover holding a digital copy of the biographical data and a digitized photograph, both cryptographically signed by the U.S. government. An NFC-enabled smartphone or a specialized e-passport reader can pull that data.
The critical step is verifying the digital signature against the issuing country’s public keys. Every country that issues e-passports maintains a chain of cryptographic keys: a country-level key signs a document-level key, which signs the individual chip’s data. Confirming that chain — a process called passive authentication — proves the chip’s contents came from the claimed government and haven’t been modified since issuance.3International Civil Aviation Organization. ICAO PKD – Epassport Validation Roadmap Tool Basics Border agencies pull the necessary public keys from the ICAO Public Key Directory. If the chip data doesn’t verify, treat the passport as suspect regardless of how it looks on paper.
Confirm the Passport Is Still Valid
Authenticity and validity are separate questions. A passport can be genuine and still be invalid.
Expiration
A U.S. passport book or card issued to someone 16 or older is valid for ten years from the issue date. One issued to someone under 16 is valid for five years. The State Department can issue a passport with a shorter validity period in certain circumstances, including cases where the applicant has reported previous passports lost or stolen multiple times.4eCFR. 22 CFR 51.4 – Validity of Passports Check the issue date, not just the expiration date, if the validity window looks unusual.
If you’re verifying the status of your own pending passport application, use the State Department’s system at passportstatus.state.gov, which asks for last name, date of birth, and the last four digits of your Social Security number.5Travel.State.Gov. Checking Your Passport Application Status
The Six-Month Rule for Travel
Many countries refuse entry if a passport expires within six months of the traveler’s return date. The passport is technically unexpired, but the destination country can still turn you away. The State Department recommends keeping travel documents valid for at least six months beyond your planned return, and checking the destination information page for country-specific requirements before booking.6Travel.State.Gov.

Conditions That Invalidate a Passport
A U.S. passport is invalid, regardless of the printed expiration date, if any of the following is true:
- It has been reported lost or stolen. Once reported, the passport is electronically canceled and cannot be used, even if the holder later finds it.4eCFR. 22 CFR 51.4 – Validity of Passports
- It’s physically damaged in a way that makes it unfit as a travel document — torn pages, water damage, a missing cover, a damaged or nonfunctioning chip, or significant wear.
- It shows any unauthorized alteration, entry, or added photograph.
- The State Department has revoked it. Grounds include outstanding federal warrants, certain tax debts, and national security concerns.
For officials with access, Interpol’s Stolen and Lost Travel Documents database holds roughly 138 million records of lost, stolen, revoked, and invalid travel documents from countries worldwide, and only the issuing country can add a document to it.7Interpol. SLTD Database (Travel and Identity Documents) Direct public access to government passport databases doesn’t exist for routine checks. That’s a design choice, not an oversight, and it shapes what non-official verifiers can realistically confirm.
A Note on the Passport Card
The U.S. passport card is a separate document, wallet-sized, valid only for land and sea border crossings into Canada, Mexico, Bermuda, and the Caribbean. It cannot be used for international air travel. Its chip uses radio frequency technology and stores only a reference number linked to a Customs and Border Protection database — no personal information is on the card itself, so chip-based verification of the card differs from verification of a passport book.2Federal Register.

Verification in Employment and Banking
For Employers
Every U.S. employer must verify a new hire’s identity and work authorization on Form I-9, and an unexpired U.S. passport satisfies both requirements on its own.8U.S. Citizenship and Immigration Services. 13.0 Acceptable Documents for Verifying Employment Authorization and Identity Employers enrolled in E-Verify get an additional check: the system compares the passport data against Department of Homeland Security and Social Security Administration records and prompts the employer to compare the presented passport photo against a government-held image.9E-Verify. Verification Process That photo-matching step is designed to catch a specific scenario: a genuine passport being presented by someone who isn’t the rightful holder.
For Financial Institutions
Banks operate a Customer Identification Program under federal anti-money-laundering rules. When a customer presents a passport, the institution records the document type, identification number, place of issuance, and any issue and expiration dates, then verifies that information through its own risk-based procedures, which may include database checks or third-party verification services. For a non-U.S. person, the bank must obtain at minimum the passport number and country of issuance.10eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks
What to Do When Something Looks Wrong
If the physical or electronic checks raise a concern, or if you receive correspondence about a passport application you didn’t submit, report it. The State Department’s Diplomatic Security Service accepts tips through its online portal, and the National Passport Information Center takes calls at 1-877-487-2778.11Department of State. Passport Fraud – DSS Crime Tips Fraud connected to a visa application processed at a U.S. embassy or consulate overseas should go to that specific post.12U.S. Department of State.

If your own passport is lost or stolen, report it immediately using Form DS-64, which can be submitted online, by phone at the same number above, by mail, or in person when applying for a replacement.13U.S. Department of State. DS-64 Statement Regarding a Valid Lost or Stolen US Passport or Card Once reported, the passport is entered into the Consular Lost and Stolen Passport System and canceled. Anyone traveling on that passport, including the original holder, can be detained on entry to the United States. Finding the passport later doesn’t reverse the cancellation — it must be submitted for destruction, and a new passport applied for.
