Can I fly with my social security card?

Social security card is a card used to record personal information and social security payment. Without the functions of identification and ticket purchase, it cannot be used as a valid certificate for flying. You need to provide identification documents, usually your ID card or passport, before you can fly. If there is an ID number on the social security card, and the social security card is issued by a government agency or an authoritative department, then in an emergency, the social security card may be regarded as a proof of identity, which can be used to buy a plane ticket or pass the security check. But it depends on the specific airlines and local regulations.
