What document would require a second identification for verifying U.S. Citizenship?

A second identification is typically required when verifying U.S. citizenship to ensure that the individual’s identity is accurate and secure. An unexpired U.S. military ID card serves as a federally issued document, confirming both the identity of the individual and their citizenship status. Military ID cards are recognized by various agencies as valid for identification purposes due to stringent issuance standards and secure personal details.

In contrast, while an expired U.S. passport, naturalization certificate, and state driver’s license may serve as valid forms of identification or citizenship, they might not have the same level of assurance for both identity and citizenship as the military ID. An expired passport is no longer a valid form of identification, and while a naturalization certificate proves citizenship, it may not always serve as a standalone identification without an additional form. State driver’s licenses can vary in their verification processes and may not always confirm citizenship without further documentation. Thus, the unexpired U.S. military ID card stands out as the most reliable document requiring no further identification to confirm citizenship.
