where do you sign your passport

You sign your passport on the page opposite your passport photo where there is a designated area labeled "Signature of bearer" or "holder's signature." Use a black or blue ballpoint pen to sign on the signature line. Do not sign below the line. The signature validates your passport, and you must sign it before using the passport for travel. If you make a mistake, you can draw a line through the signature and rewrite it above. For example, in a U.S. passport, the signature goes on the page opposite the photo. In UK passports, you sign on the "holder's signature" line with a black ballpoint pen and avoid signing below the line. Children under 11 or persons with disabilities may be exempt from signing. So, the proper place to sign is the designated "signature" line on the identity information page of your passport, which is identified clearly with a prompt to sign there.
