First-time voters

When you register to vote or vote for the first time in a federal election in your state, you must prove who you are:
  • If you register to vote in person, you must show a driver’s license, state ID, or provide the last 4 digits of your social security number (SSN), if you have one.
  • If you registered by mail and did not include your state’s driver’s license number or the last 4 digits of your SSN, you must show an acceptable form of ID (see below) at your polling place.
  • If you apply for an absentee/vote by mail ballot and did not include your state’s driver’s license number or the last 4 digits of your SSN when you registered by mail, you must include a copy of an acceptable ID (see below).
