No, a naturalization certificate number is not typically found on a passport. The naturalization certificate number is a unique identifier assigned to your naturalization certificate, which is a document issued by the U.S. government to individuals who have become U.S. citizens through the naturalization process.
Your U.S. passport, on the other hand, is a travel document issued by the U.S. Department of State. It contains information such as your name, date of birth, place of birth, passport number, and a photograph. While your passport proves your U.S. citizenship, it does not include your naturalization certificate number.
If you need to provide your naturalization certificate number for any official purposes, you will need to refer to your actual naturalization certificate, not your passport.
