In the United States, identity documents are typically the regional state-issued driver's license or identity card, while also the Social Security card and the United States Passport Card may serve as national identification. The United States passport itself also may serve as identification. There is, however, no official "national identity card" in the United States, in the sense that there is no federal agency with nationwide jurisdiction that directly issues an identity document to all US citizens for mandatory regular use.

A driver's license, driving licence, or driving permit is a legal authorization, or the official document confirming such an authorization, for a specific individual to operate one or more types of motorized vehicles—such as motorcycles, cars, trucks, or buses—on a public road. Such licenses are often plastic and the size of a credit card.
