United States passport
Identity documents in the United States are typically the regional state-issued driver's license or identity card, while also the Social Security card (or just the Social Security number) and the United States Passport Card may serve as national identification. The United States passport itself also may serve as identification. However there is 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.
