What Is a Passport Travel Document Number?

  • Contains 8 or 9 digits printed on your passport book or card
  • Unique number issued with each passport in the US
  • Identifies and authenticates travelers for national security

A passport travel document number refers to a unique 8- or 9-digit travel document number that’s printed on a passport book or passport card.

All travel documents, like passports, passport cards, Green Cards, and visas, have a unique number printed on them to identify and authenticate the traveler and help keep borders secure. 

The unique passport number helps government authorities identify you and verify your passport’s authenticity when you enter or exit a foreign country. Think of it as a social security number for your passport document!

It helps prevent the use of counterfeit passports and ensures all passports that are checked for international travel actually belong to the person presenting the document. 

The passport travel document number that’s printed on your physical passport book or passport card is also stored in a global database where it can quickly be verified as belonging to you when you present your passport for travel. 

Passport numbers are not permanent identifiers. They only apply to your current passport document and don’t last forever.

You’ll get a new passport travel document number each time you get a new passport, replace a lost passport, make changes to your passport information, or renew your passport.

Passport book numbers will be 9 digits or a combination of letters and digits long. Next Generation Passport book numbers begin with a letter followed by 8 digits.

What Do Passport Travel Document Numbers Mean?

Wondering what the seemingly random string of numbers or numbers and letters in your passport number mean? Turns out, there’s a method to the madness. 

Specific combinations of letters and numbers of your passport travel document number indicate the office where your passport was issued. 

You can look at the first 2 digits of your passport book number to determine where your passport was issued. Here’s a look at what those first 2 digits mean:

  • 01: Washington Passport Agency
  • 02: Chicago Passport Agency
  • 03 or 50: Los Angeles Passport Agency
  • 04: Miami Passport Office
  • 05: San Francisco Passport Agency
  • 06: Northeast Passport Processing Center (NYC)
  • 07: Seattle Passport Agency
  • 08 or 40: New Orleans Passport Agency
  • 09: Philadelphia Passport Agency
  • 10: Boston Passport Agency
  • 11: New York Passport Agency
  • 12 or 60: Honolulu Passport Agency
  • 13: Houston Passport Agency
  • 14: Connecticut Passport Agency
  • 15, 20, or 21: National Passport Center
  • 16, 60, 80, or 90: Special Issuance Agency
  • 17: Colorado Passport Agency
  • 30: Charleston Passport Center

For example, if your passport begins with the numbers 09, it quickly shows authorities that it was issued at the Philadelphia Passport Agency. The rest of the digits in the number are unique to you. 

Keep in mind that only passport books – ePassports and Next Generation Passports (NGPs) – can be used for international air travel.

Passport cards are only valid identification for domestic travel to US states and territories and travel by US citizens to Mexico, Canada, Bermuda, and Caribbean countries by land or sea.

Now that you know what a passport travel document number is, where can you find it? We’ll show you the location of travel document numbers on passport books, cards, visas, and Green Cards below. 

Passport Book Travel Document Number

You’ll find your 8- or 9-digit passport travel document number printed in the upper right corner of the second page of your passport book (the identification page). 

In Next Generation Passports (NGPs), your passport number will start with a letter with 8 unique digits behind it. You’ll also see the passport number printed on the bottom of each passport book page in NGPs. 

Passport Card Travel Document Number

You can find your passport travel document number on the front of your passport card, which can only be used for domestic travel to different US states and territories and for land/sea travel to Mexico, Canada, Bermuda, and Caribbean countries. 

The number will be printed in the upper right corner of your passport card, labeled as “Passport Card no.” Note that this number is not the same as your passport book number, if you have one. 

Visa Travel Document Number

If your visa is issued as a separate travel document from your passport, your visa travel document number will usually be printed in red ink on the bottom right corner of your visa. 

Your visa may also contain your passport number and a separate control number, which will be clearly labeled so you can tell the difference. 

Green Card Travel Document Number 

You can find your Green Card or Permanent Resident Card travel document number on the back of your physical Green Card. 

On the back, you’ll see a long string of letters and numbers with symbols. The Green Card number is the last 13 digits on the first line of characters and will be followed by “>>.”

You’ve got a clear understanding of what your passport travel document number is, information the number contains, and where you can find it on your travel documents. 

Take a look at a few helpful tips and things to consider to learn more below! 

  • You don’t need to memorize your passport number. This number alone isn’t valid for international travel purposes – you’ll need the entire passport book to travel across international borders. 
  • Your passport travel document number will change. Passports are only valid for 10 years or 5 years if you were under 16 when it was issued. That means passport renewal, replacement, or changes are unavoidable – and each time your passport is renewed or changed, you’ll be issued a new passport number. 
  • Know how much you can expect to pay for a passport. First-time U.S. passport applicants will pay $165 (adults) or $135 (children under 16). Passport renewals are $130 for adults. You can apply for both a passport book and card at the same time for a reduced application fee of $195 (adults) or $150 (children under 16). 
  • Apply for a passport in time for your trip. Scrambling to rush your passport application at the last minute is a travel nightmare! Avoid it by applying for your passport or passport renewal at least 10 weeks in advance of your trip, but 13 or more weeks before your planned trip is better. Current passport processing times range from 10-13 weeks or 7-9 weeks for the $60 expedited process. 
  • Make sure you’ve got the right type of travel document. Passport cards are cheaper than passport books ($65 for first-time adult applicants), so many new travelers think they can opt for the more affordable card and skip the higher-priced book. But passport cards aren’t valid for international air travel and only work for domestic travel and travel to Canada, Mexico, Bermuda, and Caribbean countries by land or sea.
