Does you passport number change when you change names?

Question: I am getting married on July 31 and am traveling to Europe on September 3rd and again on November 20th. I would like to change my name after I am married but I need to buy airline tickets before I am married. Often you have to enter your passport number when booking international tickets. Does the number stay the same and does your name just change? In that case could I book the tickets in my married name and keep the same passport number and then expedite my name change?


I have two trips to Europe planned to see family and I don't know whether to change names before both trips or in between the trips. I need to book both tickets before I get my name officially changed. Thank you.

Answer: Since U.S. passports are no longer amended, you will be issued a new passport with a new number when you apply for the name change.

You can apply for the name change after you return from the first trip to Europe. Just remember to book your airline ticket in your maiden name.

Note, you will need your original marriage certificate in order to apply for the name change. Since some states takes as much as 8 weeks to process these documents, you should request express service if it is available.
