Contact the National Passport Information Center. A Customer Service Representative will confirm the date your passport was mailed to you, the address to which it was mailed and, if necessary, help you to report the non-receipt of your passport.
You have 90 days from the date your passport was issued to report that you have not yet received it in the mail. If you do not report the non-receipt of your passport within 90 days of the issue date, you will be required to reapply and submit the full passport fee.
