What type of identification is typically acceptable for an N-400 interview?

A government-issued photo ID, such as a driver’s license or passport, is the typical form of identification acceptable for an N-400 interview. This requirement is in place because such identification serves to verify the applicant’s identity and provides a reliable source of personal information, which is crucial during the naturalization process. These forms of ID are universally recognized, carry essential details like the applicant's name, photo, and often their address, ensuring that the individual being interviewed matches the records kept by USCIS.

Other forms of identification, such as personal identification or documents that do not include a photo, like a social security card, may not provide sufficient information for identity verification. Military identification is only applicable for those who have served and may not be a standard requirement for every applicant. Therefore, a government-issued photo ID is the most appropriate and widely accepted form of identification for the N-400 interview.
