Which of the following is NOT a type of acceptable identification for purchasing a firearm in California?

When it comes to purchasing a firearm in California, specific forms of identification are required to verify a person's identity and eligibility. A driver's license provides proof of identity and residency, a passport confirms identity without requiring residency at a specific address, and a military ID serves as valid identification for service members.

In contrast, a social security card does not serve the same function as the other forms of identification. It is not designed to verify a person’s identity or residency in a way that is acceptable for firearm purchases. Rather, it primarily provides a unique identifier for individuals in relation to social security benefits and does not include the necessary personal data such as a photo or physical address that is required when purchasing a firearm. This distinction makes the social security card an inappropriate choice as identification in this context.
