Election officials use state and federal data, voter-submitted updates, address information and quality-control checks to keep those lists accurate.
The process is called voter list maintenance. It is not simply a process of deleting names. It includes adding eligible voters, correcting records, resolving duplicates, updating addresses and removing records when the law permits.
What is a voter registration list?
A voter list is the official record of people registered to vote in a jurisdiction.
The Help America Vote Act of 2002 (HAVA) requires each state, except North Dakota, to maintain a single, official and interactive statewide voter registration list for federal elections.
That list is maintained through a statewide voter registration system, a type of voter registration system used to create, store, edit and report voter records.
Why do voter records change?
A voter-registration database is not static. Records change when people register, move, change names, update party affiliation where applicable, correct errors, die, cancel registration or otherwise experience a change affecting eligibility or residence.
A voter may also update their own information through an online voter registration system, a paper application or another method permitted by the state.
Some states also use automatic voter registration, in which eligible people can have registration information created or updated through interactions with designated government agencies.
What does voter list maintenance involve?
The U.S. Election Assistance Commission (EAC) describes list maintenance as adding eligible voters, updating existing records and removing records when the law permits.
1. Address updates
Address information matters because it can determine the precinct, districts and contests assigned to a voter.
Officials may receive address changes directly from voters or through authorised sources such as postal or motor-vehicle records. If a voter moves within the same registrar's jurisdiction, the National Voter Registration Act (NVRA) generally requires an update rather than removal solely because of the move.
2. Death records
States compare voter-registration information with death records from vital-statistics agencies or other authorised sources.
When a match is confirmed, the record may be cancelled according to state law.
3. Duplicate-record checks
Registration systems can flag records that may refer to the same person.
The EAC recommends evaluating potential matches using identifying information such as name, date of birth or driver's-licence information. Confirmed duplicates can then be resolved.
A duplicate registration record does not by itself mean that a person voted twice.
4. Corrections and data quality
Election officials also correct data-entry errors, standardise addresses and review records that do not match cleanly to a residence or precinct. The EAC recommends routine transaction and quality-control reviews.
What is a master voter registration list?
A master voter registration list is the official computerised list of registered voters. Under HAVA, the statewide list serves as the official voter-registration list for federal elections.
What do active, inactive and cancelled statuses mean?
Election offices use registration status labels such as active, inactive and cancelled, although the exact terminology varies by state.
An inactive record does not automatically mean the voter is ineligible. Under an NVRA address-confirmation process, a voter who does not respond may be placed in inactive status while remaining registered and potentially able to vote after confirming an address as required by state law.
A cancelled record generally means the registration is no longer active in that jurisdiction.
What is a confirmation mailing?
A confirmation mailing is a notice sent to a voter to verify address information or another change in the voter record.
Under the NVRA process for certain suspected changes of residence, the notice must be forwardable and include a prepaid, pre-addressed return card.
If the voter confirms in writing that they moved outside the jurisdiction, the registration can be removed.
If the voter does not respond, the record cannot simply be cancelled immediately. Under the NVRA process, removal generally requires both failure to respond and failure to vote or appear to vote through the second federal general election following the notice.
Can a voter be removed simply for not voting?
No.
Federal law prohibits removing a registrant solely because the person failed to vote.
Non-voting can be one part of a longer statutory process after notice, but it cannot be the sole reason for cancellation.
What is the 90-day rule for voter list maintenance?
The NVRA limits certain systematic removal programmes close to a federal election.
For jurisdictions covered by the NVRA, a programme that systematically removes voters believed to be ineligible must generally be completed no later than 90 days before a primary or general election for federal office.
That does not mean every voter-record change must stop for 90 days.
The Department of Justice explains that the restriction still permits specified individual changes, including voter-requested removals, death removals, certain removals based on criminal conviction or mental incapacity under state law, and corrections.
The NVRA applies to 44 states and the District of Columbia; Idaho, Minnesota, New Hampshire, North Dakota, Wisconsin and Wyoming are exempt under the statute.
Does a database match automatically remove a voter?
It should not be treated as proof by itself.
Another database may flag a potential duplicate, death or address change, but officials still apply state matching criteria and legal procedures before changing or cancelling a registration.
Names and dates of birth can match across different people, and records can contain errors. The EAC therefore emphasises transaction review, address validation and review of potential duplicate matches.
How does HAVA protect both accuracy and eligible voters?
HAVA requires states to conduct regular list maintenance while also including safeguards against removing eligible voters incorrectly.
The EAC summarises the objective as keeping registered voters on the statewide list, removing only records that may lawfully be removed and eliminating duplicates.
An accurate list is therefore not simply the shortest possible list; it should accurately reflect eligible registered voters.
Why does voter-list maintenance matter for election administration?
A correct registration record can determine a voter's precinct, districts, ballot style, election mail and poll-book information.
Accurate records therefore support correct ballot assignment, efficient voter check-in and reliable election administration.

Frequently asked questions
1. Does an inactive voter status mean someone cannot vote?
Not necessarily. “Inactive” often indicates that the election office needs updated or confirmed information, particularly an address. Under NVRA procedures, an eligible inactive voter can remain on the registration list and may be able to vote after completing the confirmation steps required by state law.
2. Why might someone still receive election mail for a person who moved or died?
Election offices may not immediately receive reliable information about every move or death. Returned mail, voter reports, postal data, vital-statistics records and other authorised sources can help officials identify records that need review. A record is changed according to the jurisdiction's legal process.
3. Does having registrations in two states mean someone voted twice?
No. A person who moves can temporarily have registration records in more than one jurisdiction until list-maintenance processes identify and resolve the older record. Duplicate registration records do not by themselves establish that multiple ballots were cast.
4. Can election officials remove large numbers of voters just before a federal election?
The NVRA generally requires covered jurisdictions to complete systematic removal programmes no later than 90 days before a federal primary or general election. Specific individual removals and corrections can still occur under statutory exceptions, and state rules also apply.
