How to Vote

Check your registration in about 30 seconds. Even if you registered years ago, states occasionally remove voters from the rolls, so it's worth confirming before every election.

Check your registration at vote.gov

Most states let you register online in a few minutes. You'll need a government ID or the last four digits of your Social Security number. Some states also allow same-day registration at the polls.

• A photo ID if your state requires one (most do — check your state's rules).
• Your voter registration card if you have it (not required in most states).
• A phone or printed sample ballot so you're not making decisions cold.
• Water, a snack, and patience — lines can be long during peak hours.

You may still be able to vote. About 20 states and Washington, D.C. offer same-day registration, meaning you can register and cast your ballot on the same visit — usually with proof of ID and residence.

Every state allows some form of mail voting, though the rules vary. Some states mail every voter a ballot automatically. Others require you to request one, sometimes with an approved reason.

Steps that apply almost everywhere

1. 1Request your mail ballot before your state's deadline (see our deadlines page).
2. 2Read the instructions on the return envelope carefully — a missing signature is the #1 reason ballots get rejected.
3. 3Mail it back early, or drop it off at an official drop box or your local elections office.

You have the right to cast a provisional ballot. Ask for one out loud, fill it out, and submit it. Poll workers must accept it. Your ballot will be counted once your eligibility is confirmed.
