Getting on the list, staying on it, and making your ballot count.

Between the 2022 and 2024 elections, election offices processed more than 103 million registration transactions: new voters, moves, name changes, removals.^[8] Your record is one of them, and it is kept by your state, not by Washington, on a single statewide list run by your chief election official.^[4] Whether that record is right on Election Day decides whether you vote the ordinary way or spend twenty minutes at a table filling out paperwork.

Federal law makes it much harder to take you off the list than to put you on it. You can be removed only for a short list of reasons, never for simply not voting, and never in a mass sweep in the last 90 days before a federal election.^[3] A private group that challenges your registration cannot remove you by itself.^[7] And if your name is missing at the polls anyway, you still get a ballot.^[5]

It depends on your state. For a mail application in a federal election, federal law caps the deadline at 30 days before the election; a state may set a shorter one but not a longer one.^[3][1] States fall into three rough groups: 28 to 30 days out, 20 to 27 days out, and 1 to 19 days out.^[1] If you register by mail, the postmark is what counts.^[3]

Missing the deadline is not always the end. As of March 2026, 24 states and Washington, D.C. offer same-day registration, which lets you register and vote in the same visit; 17 of those states plus D.C. allow it throughout early voting as well as on Election Day.^[2] The federal form is simple by law: it may ask only for what is needed to judge eligibility, it cannot require a notary, and it asks you to answer a citizenship question and sign under penalty of perjury rather than attach a document.^[9][6] Federal law does require a driver's license number or the last four digits of your Social Security number with a new application.^[4]

Only for the reasons the law lists: at your own request, on death, on a criminal conviction or a finding of mental incapacity where state law provides for it, or because you moved, and a move has its own procedure.^[3] A state may not remove you because you did not vote.^[3] To remove you for moving, the state needs either your written confirmation or a mailed notice, with a prepaid return card sent by forwardable mail, that you did not answer, followed by two federal general elections in which you did not vote.^[3] If you moved within the same registrar's area you cannot be removed at all; the office has to correct your address.^[3]

The last 90 days before a federal primary or general election are a quiet period: any systematic program to remove voters must be finished before it starts.^[3] A federal citizenship list sent to your state under the 2026 executive order does not change any of this; the grounds, the notice procedure and the quiet period still apply.^[3] States must keep their list-maintenance records for at least two years and open them to public inspection, and a person can sue over a violation, usually after giving written notice and waiting, with no notice required when the violation is within 30 days of a federal election.^[3][10]

Private tools now generate mass challenges to individual registrations: one publishes voter data covering more than 161 million voters across 31 states and D.C., another cross-references address changes, and courts and election officials have described the resulting challenges as error-ridden.^[7] A challenge is a claim, not a removal. The federal limits above still govern what your state can do with it.^[7][3]

If you are worried, check your registration with your state or county before Election Day and fix anything wrong while there is time. And if you arrive at the polls and your name is not on the list, or a worker says you are not eligible, federal law guarantees you a provisional ballot. It is counted once officials find you were eligible, and every state must run a free way, a phone line or a website, for you to find out whether it was counted and, if not, why.^[5]
