Passport applicants are able to self-certify their gender, and parents are able to self-certify the gender of their children. At this time, applicants can select male (M), female (F), or unspecified/another gender identity (X) as your gender marker when applying for a U.S. routine passport book.
The gender you select does not need to match the gender on your supporting documentation such as a birth certificate, previous passport, or state ID. We no longer require medical documentation to change the gender marker on your U.S. passport.
Visit our Passport Forms page for more information about which form you should use.
