The process can include cast, spoiled, provisional, emergency and unused ballots. Reconciliation is about accounting for quantities and records; it is not the same as recounting votes or determining voter intent.
What Is Ballot Reconciliation?
The U.S. Election Assistance Commission (EAC) describes ballot reconciliation as tracking each ballot printed or issued during an election cycle.
A closely related ESG term is vote reconciliation: comparing voter records with ballots cast. Ballot accounting is broader inventory accounting covering categories such as voted, spoiled, provisional, emergency and unused ballots.
The objective is to make the election records explain what happened to the ballots.
What Numbers Are Compared During Reconciliation?
The exact records depend on the voting method and equipment.
For Election Day voting, officials may compare:
- voters checked in;
- cast ballots;
- provisional ballots;
- spoiled or replacement ballots;
- emergency ballots;
- unused ballot inventory; and
- scanner or voting-device counts.
A simple paper-ballot reconciliation might ask whether:
ballots provided = cast + spoiled + provisional + other accounted-for ballots + unused ballots
That is an illustration, not a universal legal formula. States and voting systems use different categories and records.
Election Day Reconciliation
Before polls open, EAC guidance recommends verifying ballot quantities and styles and confirming voting-device counts begin at zero where applicable.
During and after voting, officials compare check-ins, ballots cast, provisional and spoiled ballots, unused inventory and device reports.
A difference is not automatically evidence that a ballot is missing or that an extra vote was counted. For example, a voter may check in and leave before casting a ballot. The EAC notes that such an event can be documented so the numbers can be explained during reconciliation.
Early Voting Reconciliation
Early voting can continue for days or weeks, so the EAC recommends reconciliation each day.
Officials can record starting ballot inventory, voter check-ins, ballots cast and spoiled ballots, then verify the unused inventory remaining. E-pollbooks can provide check-in records.
Daily reconciliation helps identify discrepancies while events are still recent.
Mail Ballot Reconciliation
Mail voting requires a different accounting trail.
EAC guidance recommends tracking mailed ballots from preparation through return and processing. Records can include ballots sent, returned or undeliverable; drop-box returns; challenged or reissued ballots; and ballots accepted for counting.
The purpose is not to assume every mailed ballot will return. It is to explain the status of ballots and related records throughout the process.
What Happens When the Numbers Do Not Match?
Officials investigate the difference and document the explanation.
Possible causes include recording errors, misclassified spoiled ballots, a voter who checked in but did not vote, an unrecorded provisional ballot or a mismatch between polling-place and scanner records.
The goal is to explain the discrepancy rather than force the figures to match.
Records of these events form part of the election's audit trail, allowing later reviewers to reconstruct what occurred.
Reconciliation vs Chain of Custody
No.
Reconciliation asks: Do the counts and records account for the ballots?
Chain of custody asks: Where were the ballots, who handled them and when were they transferred?
The controls support each other but answer different questions. A ballot manifest identifies how physical ballots are organised and stored; reconciliation asks whether quantities and records balance.
Reconciliation vs Audits and Recounts
No.
A recount repeats the counting of votes. A post-election audit tests aspects of the reported outcome or election process.
Ballot reconciliation does not normally determine which candidate received each vote. It checks whether ballot and participation records are internally consistent.
Reconciliation records can later support canvassing, audits or certification, but those are separate processes.
Why Ballot Reconciliation Matters
Reconciliation creates an early control for detecting mistakes and unexplained differences.
It helps officials account for valid, spoiled and unused ballots and compare participation records with ballot totals. Apparent mismatches can then be investigated and documented.

Frequently Asked Questions
1. Do voter check-ins and ballots cast always have to be identical?
They should be compared, but a difference can have a documented explanation. A voter may check in and leave without casting a ballot, for example. Reconciliation is used to identify and explain such differences.
2. Is a spoiled ballot counted as a vote?
No. A spoiled ballot is accounted for in ballot inventory but is not counted as a cast vote. Jurisdiction procedures govern how it is marked, stored and replaced.
3. Are provisional ballots included in reconciliation?
Yes. Provisional ballots are tracked as a separate category while eligibility is reviewed. Whether they later count is determined through the provisional-ballot process, not through reconciliation itself.
4. Does reconciliation happen only after Election Day?
No. EAC guidance recommends reconciliation during Election Day and daily during early voting, while mail-ballot reconciliation can occur throughout mailing, return and processing.
