Once you receive your U.S. passport, don’t forget to sign it!
Adult passports (age 16 and up): You must sign your full name in blue or black ink inside your passport.
Child passports (under age 16): A parent should print the child's full name on the signature line. The parent should also sign their name next to the printed name of their child and note their relationship to the child, such as mother, father, or guardian.
