How old do you have to be to get a passport?
There is no minimum passport age for getting a passport. Every international travel requires individuals, regardless of their age, to carry a valid passport.
Therefore, parents should provide passports to their children, no matter if they are newborns, toddlers or teenagers. Every airline and border crossing authorities require travelers to show the document that allows them to enter another country—that is, a passport book.
Note: A U.S. passport card is not an acceptable form of document while traveling internationally. Learn about differences between passport books and passport cards.
Passport requirements for children
In addition to all the documents required for an adult’s application, children will need:
- a signed statement from both parents or legal guardians and their photo IDs,
- a birth certificate, and
- photocopies of all the listed documents.
Bear in mind that during the passport application, at least one parent needs to accompany the child. Check also the application procedures for single parents.

When are passports required: exceptions?
A child’s passport is not always mandatory to the point that no other identity document will suffice.
The first and most common case is domestic flights. When flying inside the country, U.S. citizens are not required to have a passport—most forms of ID, like birth certificates, will be good enough.
Another exception is for land and sea travel to Canada, Mexico, and certain Caribbean islands.
For these destinations, children under 16 (sixteen) may only need a birth certificate to cross the border. Also, for closed-loop cruises, a passport book will not be required.
However, parents should remember that passports are the strongest traveling documents. Even though one cruise company may not require them, the other demands passengers to carry passports. Thus, it is always the best idea to apply for your child’s passport if you plan international trips.
