How do I check if I'm registered to vote?
Short answer
Check your registration through your state election authority's official voter lookup, which will confirm your status, your polling place, and your districts. Do this several weeks before Election Day, because registration deadlines in many states fall 15 to 30 days before an election and a lapsed registration cannot always be fixed at the polls.
Why registrations lapse
The most common reason is moving. Registration is tied to your residential address, and moving — even within the same county — generally requires updating your record. An out-of-date address can send you to the wrong polling place or leave you voting a provisional ballot.
States also periodically remove registrations through list maintenance: undeliverable mail, death records, felony convictions in states where that applies, or extended inactivity followed by a required notice period. A name change through marriage or divorce can also create a mismatch.
Deadlines vary widely
Registration deadlines range from about 30 days before an election to same-day registration at the polls, depending on the state. Many states also allow same-day registration during early voting but not on Election Day itself.
Because the rules differ so much, the deadline published by your own state election authority is the only one that matters. Check it as soon as you think about voting, not the week of the election.
If something is wrong
Contact your county election office directly. Most registration problems — a wrong address, a misspelled name, a missing party affiliation for a closed primary — can be corrected quickly if you catch them before the deadline.
If you arrive at the polls and your registration cannot be confirmed, you have the right to cast a provisional ballot. It will be counted if officials later verify your eligibility, so never leave without voting provisionally.

Does my registration expire if I skip an election?
Not immediately. Federal law prohibits removing voters solely for not voting. States may begin an inactivity process after a voter misses elections and fails to respond to a mailed confirmation notice, but that process requires notice and a waiting period.
What is a provisional ballot?
A ballot cast when your eligibility cannot be confirmed at the polling place. It is set aside and counted once election officials verify your registration. If you are told you are not on the list, ask for one.
