Does your passport number change when you renew it?

The short answer is yes. You will get a new passport and a different number with it. The most crucial moment here is to make sure your plane tickets contain your new passport digits, even if you booked the ticket using your old document.

What is a passport number?

A passport number is a serial unique digits. You can find it on the first page of the passport book together with the holder’s photo and information.  It highlights the passport office (the passport was issued in) and its applicant, according to the Social Security Administration. It’s vital when applying for visas. Your passport number identifies your unique ID. It is also needed when booking a flight.

Here are a few interesting cues. The correlation between the US passport number and the location of issuance is an interesting fact:

  • If the passport number starts with 01, it means the document came from the Washington Passport Agency,
  • 04 for Miami,
  • 15, 20, or 21 for the National Passport Center in New Hampshire,
  • 60 for no-fee passports for military dependents,
  • 80 for official documents,
  • 90 for diplomatic documents,
  • The letter Z or the number 70 for embassy or consulate overseas replacement, issued after 2002 as an emergency document with one-year validity.
