My husband (the USC) is in the process of renewing his passport but I have to plug in his passport # for one of the flights. (Re-entering US from Europe.) Does anyone know if the passport # changes from the existing passport to the renewed passport? I don't want to give them the current # if the new one comes with a different #.

Thanks very much for any help you can give me.

Every time I've renew my UK passport the number changes. When I worked alongside immigration at Heathrow I did their forgery course and they said then that the passport numbers for just about every country changed when a new one was issued.

Thanks, again, Lansbury.

Yes, it does change. I just pulled out my current and expired US passports to check, and the numbers are indeed different.

yeah, my first job in the philippines is in Department of Foreign Affairs...yeah it change coz the booklet number is different also...they're making that with numbers and will trace up how many passport they've made and track the number and person who get it;-) hope it helps
