There are many types of valid U.S.-government-issued (or state-issued) photo IDs. A driver's license or other DMV-issued ID card, a passport or sometimes even a foreign-government-issued photo ID can be used in the United States. Usually, there are requirements for such an ID: it must at least list a birthdate, a photograph and an issue date. Sometimes height and weight will also be required. Valid photo IDs are required to do such things as buy alcohol and apply for passports, social security cards and library cards.
A driver's license issued in any of the 50 U.S. states qualifies as a primary identification when applying for a U.S. passport. When using a driver's license from a state other than that in which the application is being submitted, secondary identification must be provided containing a full name, a birthdate, a photograph and the date issued. A driver's license, from any state or from Washington, D.C., is valid when buying alcohol in the U.S., since it can be used to verify age. Virginia, for example, issues special licenses to drivers under 18 that state age clearly. A driver's license is also valid when applying for a library card. The same may be used when proving identification in order to apply for a social security card.
A previously-held U.S. passport is a valid form of ID when applying for a new U.S. passport. A valid passport may also be used to buy alcohol in the U.S and to obtain a library card as well as a social security card. In applying for a social security card or a renewed passport, a valid U.S. passport establishes identity as well as U.S. citizenship.
U.S. Military ID Cards
A military ID card qualifies as a valid form of photo ID in applying for a U.S. passport. A military ID card is also valid proof of age when attempting to buy alcohol in the U.S. since it contains a birthdate and a photo. The same is true in the case of applying for a library card. A U.S. military ID card may also be used in proving identity in order to obtain a social security card.
Other Photo IDs Issued by State or Federal Agencies
Any other form of photo identification issued by a U.S. state or federal agency (such as an employee identification card) may be used both in buying alcohol and in applying for a U.S. passport. A valid state or federal identification card may also be used in applying for a library card. An employee identification card from a state or federal agency also qualifies as proof of identity when applying for a social security card.
