Voter registration deadlines explained

Why deadlines vary so much

Because elections are run at the state level, each state sets its own registration deadline. In practice they fall along a wide range: some states require you to register up to about 30 days before an election, while several allow same-day registration right through Election Day. There is no single national deadline.

Three deadlines to watch

Many states set different cutoffs depending on how you register. It helps to think of them separately:

Online deadline

Where online registration is offered, it usually has its own cutoff, often a set number of days before the election.

Mail deadline

Mail registration is typically judged by a postmark or receipt date. Give it plenty of time — delivery is out of your control, so don't wait until the last day.

In-person deadline

In-person deadlines vary, and this is where same-day registration often applies: in many states you can register and vote in the same visit during early voting or on Election Day.

The simple rule: register early

You never lose anything by registering early, and you avoid every deadline problem at once. If you're not sure of your state's date, check it now rather than later. You can also confirm your current status at the same time.

Find your state's exact deadline

We deliberately don't list a date for each state here, because deadlines change and a stale figure could mislead you. Instead, open your state's official page — it always has the current, authoritative date. You can also browse every state through the U.S. Election Assistance Commission.
