There is no public database, search engine, or records request that lets you look up someone else’s passport number, and the only way to look up your own is to check documents where you already recorded it or to request your records from the U.S. Department of State. Passport numbers are protected personal information under the Privacy Act of 1974, and access is limited to the passport holder, a parent or guardian of a minor, an authorized designee, or specific government agencies with a legal basis.
Why You Can’t Look Up Someone Else’s Number
The State Department keeps passport records in a system called “Passport Records, State-26,” governed by the Privacy Act. Federal regulations at 22 CFR 171.22 spell out the only route in: a written request that is either notarized or signed under penalty of perjury, accompanied by a copy of the requester’s government-issued photo ID.1eCFR. 22 CFR Part 171 – Public Access to Information A Freedom of Information Act request will not return another person’s passport number. Private investigators have no legal channel to query the database either.
Airlines, banks, and employers do handle passport numbers, but they collect them directly from the traveler, customer, or employee. None of them can look a number up on your behalf, and none of them have a search tool for the State Department’s records.
Finding Your Own Passport Number Without the Book
If you have the passport itself, the number is on the data page with your photo. On the current Next Generation passport book, it is an alphanumeric code that begins with a letter followed by eight digits, printed in the top right corner of the data page and repeated at the bottom of every page.2U.S. Department of State. Information about the Next Generation U.S. Passport Older passports used a different format but appear in the same location.
If the physical passport isn’t available, check the easy places first:
- Photos or scans of the data page saved to your phone, email, or cloud storage.
- Old visa applications, whether U.S. or foreign.
- Airline and hotel loyalty profiles, which often store travel document details.
- Copies of prior DS-11 or DS-82 passport application forms you may have kept.
- Travel insurance policies, cruise bookings, or Global Entry files.
Most people find the number in one of those places before needing to go further.
Requesting Your Passport Records From the State Department
If nothing turns up, you can write to the Department of State for copies of your passport records. Send your request to:
U.S. Department of State
Office of Records Management
Records Review and Release Division
44132 Mercure Cir
P.O. Box 1227
Sterling, VA 20166
The letter must be notarized or signed under penalty of perjury. It needs to include your full name at birth and any other names you have used, your date and place of birth, your current mailing address and contact information, the date or estimated date the passport was issued, and a clear copy of both sides of a valid government-issued photo ID such as a driver’s license.1eCFR. 22 CFR Part 171 – Public Access to Information
A regular copy of your records is free. Certified copies cost $50, payable by check or money order to “U.S. Department of State.”3U.S. Department of State. Get Copies of Passport Records Processing takes 12 to 16 weeks, so this is not a same-week solution.
Looking Up a Minor Child’s Passport Number
A parent or legal guardian can request records for a minor child by writing to the same Sterling, Virginia address. The letter must include the child’s full name at birth and any other names used, the child’s date and place of birth, and the passport number or estimated issuance date if known. The parent must also provide their own full name, contact information, a clear copy of both sides of their government-issued photo ID, and evidence of their legal authority and relationship to the child using Form DS-4240-R. Like a personal request, the letter must be notarized or signed under penalty of perjury.3U.S. Department of State. Get Copies of Passport Records Processing also runs 12 to 16 weeks.
No other relationship qualifies for this route. A spouse, adult child, sibling, or friend cannot request the records on someone else’s behalf without formal authorization from the passport holder.
If the Reason You Need the Number Is a Lost or Stolen Passport
People often go looking for a passport number because the passport itself is missing. If yours is lost or stolen, reporting it should come before, or at least alongside, any effort to retrieve the number. Once you report a passport lost or stolen, it is permanently invalidated. Even if you find it later, you cannot use it for travel and may be denied entry to a foreign country if you try.4U.S. Department of State. Report Your Passport Lost or Stolen
You can report the loss:
- Online through travel.state.gov.
- By phone at 1-877-487-2778 (TDD: 1-888-874-7793). Phone reporting isn’t available for people abroad.
- While applying for a replacement, by submitting Form DS-64 along with Form DS-11 at any passport acceptance facility, passport agency, U.S. embassy, or consulate.
- By mail, only if you are not applying for a new passport, by sending Form DS-64 and a photocopy of both sides of a valid government photo ID to the Consular Lost and Stolen Passport Unit at the Sterling, VA address.5U.S. Department of State. DS-64 Statement Regarding a Valid Lost or Stolen US Passport or Card
The longer an unreported passport stays active, the more it can be used against you.
Avoid Websites That Claim to Look Up Passport Numbers
Any site advertising a passport number lookup service for a fee is a scam. No third party has access to the State Department’s passport database. The Federal Trade Commission has warned consumers about websites that use names, flags, and seals designed to mimic official government sites; they charge anywhere from $60 to several hundred dollars, and in return you get nothing except the risk that your personal information will be sold to identity thieves.6Federal Trade Commission. Avoid Scam Websites That Offer to Help You Get or Renew Your Passport
Two quick tells: all official passport forms are free on the State Department website, and State Department passport agencies never charge for appointments. If a site is charging for either, it isn’t the government.
Penalties for Using Someone Else’s Passport Number
Federal law treats passport numbers as identification documents, and misusing another person’s number is a federal crime. Producing, transferring, or using someone else’s identification, which explicitly includes a passport number, can carry up to 5 years in prison. Using it to obtain anything of value worth $1,000 or more in a year raises the maximum to 15 years. Connections to drug trafficking or violence push it to 20 years, and to terrorism, 30 years.7Office of the Law Revision Counsel. 18 USC 1028 – Fraud and Related Activity in Connection With Identification Documents Passport-specific statutes add more: making a false statement on a passport application or using a fraudulently obtained passport carries up to 10 years for a first or second offense, and up to 25 years if the crime facilitates international terrorism.8Office of the Law Revision Counsel. 18 USC 1542 – False Statement in Application and Use of Passport
The short version: the reason there is no lookup tool for other people’s passport numbers is the same reason the penalties are steep. A number paired with a name, date of birth, and photo is enough to do real harm, and the law is built to keep it that way.
