Identity documents in the United States

The birth certificate is the initial identification document issued to parents shortly after the birth of their child. The birth certificate is typically issued by local governments, usually the city or county where a child is born. It is an important record, often called a ``feeder document,'' because it establishes U.S. citizenship through birthright citizenship, which is then used to obtain, or is the basis for, all other identity documents. By itself, the birth certificate is usually only considered proof of citizenship but not proof of identity, since it is issued without a photograph at birth, containing no identifying features. A birth certificate is normally produced along with proof of identity, such as a driver's license or the testimony of a third party (such as a parent), to establish identity or entitlement to a service.
