How can I find my passport number?

Question: I cannot find my passport and want to find the passport number, which I need for filling out other documents. How can I find my passport number?

Answer: If your passport is misplace, the State Department encourages citizens to report those lost passports. Passports are a valid form of personal identity and loss subjects the owner to potential identity theft situations.

If you wish to obtain your passport number, you must follow the following specific process:

1. Send a written request via U.S. Postal service requesting your passport records. You must sign this request and have it notarized.
2. Include in the request the following information:

A) Full name, and any name changes that may have taken place (marriage, name change, other)

B) Date of birth, birthplace

C) The full names of children if you are requesting the records for children

D) Your current mailing address

E) Telephone number

F) Email (if you have one)

G) The estimated or exact date your passport was issued

H) Copy of a valid recent photo

I) The reasons for the request

J) Any information you may have such as a passport number, which will assist in the proper location of the record.

 The notarized request should be mailed to:

Department of State
Passport Services
Research and Liaison Section
Room 500
1111 19th Street, N.W.
Washington, DC 20524-1705 (202) 955-0447

You should allow up to 60 days before getting the information. We suggest that you mail the request “certified mail” to substantiate the request in case you do not hear back in a timely manner.
