As proof of citizenship

The State Department lists a full-validity, undamaged U.S. passport as primary evidence of citizenship for a new passport application. This applies to a passport that has not been damaged. A passport issued after age 16 is valid for 10 years, and one issued under age 16 is valid for 5 years.

Applying

First-time adult applicants must prove citizenship and identity. The State Department's guidance lists the evidence it accepts. Check the State Department site for current forms, because requirements can change.
