Can you find your passport number online?
No. There is no government website, public database, or online tool that lets you look up your U.S. passport number. The Privacy Act protects passport numbers as sensitive personal information, and the State Department does not offer any online portal for retrieval. Full stop.
If you are reading this because you lost your passport or need the number for a form, you have two realistic paths: request the record officially by mail, or check secondary sources where the number may already be stored.
Before anything else, know what to avoid:
- No legitimate online lookup exists. Any website claiming to retrieve your passport number for a fee is almost certainly a scam.
- Third-party "passport lookup" sites are active identity theft threats. They collect your personal data and return nothing useful.
- Government agencies do not provide passport numbers by phone, email, or fax to the general public.
- Searching for your passport number online exposes you to phishing pages designed to look official.
Pro Tip: If a site asks for your Social Security number, date of birth, or payment information in exchange for a "passport number lookup," close the tab immediately and report the site to the FTC at reportfraud.ftc.gov.

How to officially retrieve your passport number without the physical document
The only legitimate way to retrieve your U.S. passport number without the physical passport is to mail a written request to the Department of State's Office of Records Management. There is no online submission option, and phone, fax, or email requests are not accepted from the general public.
Here is exactly how the process works:
-
Write a formal written request. Include your full legal name, date of birth, place of birth, approximate passport issue date, and the passport number if known. State clearly what records you are requesting.
-
Sign the request correctly. Your signature must be notarized by a licensed notary public, or you must sign under penalty of perjury as defined under 28 U.S.C. 1746. Unsigned or improperly signed requests are rejected outright.
-
Include proof of identity. Attach a copy of a government-issued photo ID such as a driver's license or state ID.
-
Choose your copy type. Standard copies carry no fee. Certified copies cost $50 and are required for legal proceedings.
-
Mail everything to the correct address. Send your request to the Department of State's Office of Records Management. The current mailing address is listed on the State Department's official passport records page at travel.state.gov.
-
Wait up to 12 weeks. Processing is not fast. If travel is imminent, do not rely on this process to get your number in time. Pursue the alternatives below while your request is in transit.
Incomplete requests slow everything down. Double-check that your signature meets the legal standard and that your proof of identity is clear and legible before mailing. See supporting documents guidance for more on what the State Department expects.

Where else you might find your passport number right now
Before waiting 12 weeks for a mail-in response, check these sources. Your passport number may already be stored somewhere accessible.
- Airline frequent flyer accounts. Most major carriers store the passport number you entered when booking international flights. Log in and check your profile or past booking details.
- Travel booking portals. Sites like Expedia, Kayak, or your corporate travel platform often save passport data from previous international reservations.
- Visa application records. If you have applied for a foreign visa, your passport number appears on the application, approval letter, or visa stamp itself.
- Hotel check-in records. International hotels frequently scan or record passport numbers at check-in. Contact the hotel directly and request your record.
- Email confirmations. Search your inbox for past flight bookings, visa confirmations, or travel insurance documents. The number often appears in the body of those emails.
- Saved digital copies. If you ever photographed or scanned your passport data page and saved it to cloud storage, a secure folder, or emailed it to yourself, that copy contains the number.
- Travel insurance documents. Policies purchased for international trips often require and record your passport number.
Handle any digital copies carefully. Do not share them over unsecured channels, and store them in an encrypted folder or a password-protected app rather than a standard photo library. For practical advice on protecting your passport during and between trips, Passportcenter covers the key decisions travelers face.

Applying for a new passport when you don't know your old number
Good news: you do not need your old passport number to apply for a new one. Official State Department guidance confirms that the previous passport number is not a required field when the document is lost or unavailable.
Here is what you do need:
- Completed Form DS-11 (for first-time applicants or those who cannot renew by mail)
- Proof of U.S. citizenship such as a birth certificate or naturalization certificate
- Government-issued photo ID and a photocopy of it
- One passport photo meeting the State Department's current specifications
- The applicable fee (check travel.state.gov for current amounts, as fees are updated periodically)
If your passport was lost or stolen, file Form DS-64 to report it before applying for a replacement. Once reported, the State Department invalidates the old passport. Even if you later find it, a reported passport cannot be used.
If travel is coming up soon, do not wait. Routine processing currently takes several weeks. Expedited processing is faster, and registered passport courier services can accelerate the timeline further for urgent situations. Passportcenter connects travelers to those services when time is short.

Security precautions every traveler should take with passport information
Most people only think about passport security after something goes wrong. A few simple habits prevent the problem entirely.
- Store a secure digital copy now. Photograph your passport data page and save it in an encrypted app or a password-protected cloud folder. The State Department recommends keeping a copy in a secure location for exactly this situation.
- Never share your passport number over unsecured channels. Text messages and standard email are not secure enough for this data.
- Verify every website before entering personal information. Official State Department pages use travel.state.gov. Any other domain claiming to be the government is not.
- Do not use third-party "passport lookup" services. These sites are identity theft threats, not tools.
- Keep a written record in a secure location at home. A locked drawer or a home safe works. This is your fastest retrieval option if the passport itself goes missing.
Pro Tip: Use a password manager with secure notes (such as 1Password or Bitwarden) to store your passport number, issue date, and expiration date. It is encrypted, accessible from anywhere, and far safer than a screenshot in your camera roll.
When passport numbers are legally accessible online
There are a small number of situations where passport-related information appears in an online system, though these are narrow and controlled.
Government-to-government systems use passport data for border security and entry verification, but these systems are not accessible to the public. Customs and Border Protection, for example, uses passport data during international travel processing.
The National Archives holds historical passport records for genealogical research. These are digitized passport applications from the 19th and early 20th centuries, not modern records, and they do not include passport numbers in the modern sense.
Your own airline or travel portal account is technically an online system where your passport number may appear, as noted above. That is the closest most travelers will get to accessing their number online, and it is entirely legal because you entered the data yourself.
No portal exists where you can type your name and retrieve a current U.S. passport number. That access simply does not exist for the public, by design.
What to do if your passport number has been exposed or compromised
If you believe your passport number has been stolen or exposed, act quickly. The damage from passport data exposure is real, and the steps below limit it.
-
Report a lost or stolen passport immediately using Form DS-64 online at travel.state.gov, by phone at 1-877-487-2778, or by mail. Once reported, the passport is invalidated and cannot be used fraudulently.
-
Place a fraud alert with the major credit bureaus. Contact Equifax, Experian, or TransUnion. A fraud alert is free and makes it harder for someone to open accounts in your name.
-
Consider a credit freeze. A freeze at all three bureaus is the strongest protection against new account fraud. It is free under federal law.
-
Monitor your accounts. Watch for unfamiliar activity on financial accounts, and check your credit report at AnnualCreditReport.com.
-
File a report with the FTC at IdentityTheft.gov if you believe identity theft has occurred. The FTC provides a personalized recovery plan.
-
Apply for a new passport promptly. Once the old one is reported and invalidated, apply for a replacement so you have a valid travel document. Not knowing your old passport number does not delay this process.
