Election night can reveal a likely winner before the official work is finished. An election canvass checks the fuller record before the results are certified.
We treat early totals as useful information with a status attached: they show votes reported so far, while required counting and review may continue. A media projection doesn't replace that work, and an unofficial label doesn't establish misconduct.
To understand how a tally becomes an official result, start with what officials must check.
Election-night totals answer a limited question
A county results page reports the votes that office has released at a particular time. A statewide page combines available local reports. Neither necessarily includes every eligible ballot.
Mail ballots may still need processing. Provisional ballots may still need eligibility review. Military and overseas ballots follow deadlines and procedures that vary by state.
These stages tell you different things.
| Stage | What it tells you | What it doesn't establish |
|---|---|---|
| Unofficial tally | Votes counted and reported so far | That every eligible ballot is included |
| Media projection | A newsroom's judgment about the likely winner | That officials have certified the outcome |
| Canvassed totals | Results assembled and checked through the required review | That every later legal challenge is resolved |
| Certified results | Results formally approved under the applicable process | That no recount or legal proceeding can follow |
We keep the source and status together. A television map may change because a newsroom called a race, even without a new release of votes.
Likewise, "100% of precincts reporting" may mean every precinct submitted an initial report. It may leave other ballots outstanding. Check the election office's definition before treating that percentage as completion.
What an election canvass checks
The election canvass is a formal accounting and verification process. Officials compare election returns, ballot records, voter participation records, and reported totals.
The U.S. Election Assistance Commission's canvass and certification guidance describes this post-election work. Its purpose is to establish accurate results through review, reconciliation, and resolution of discrepancies.
Account for ballots and election records
Reconciliation means comparing records that should agree and explaining differences. Depending on local procedures, that can involve poll books, ballot inventories, tabulator reports, mail-ballot records, and precinct returns.
Officials check whether the records account for ballots issued, returned, counted, spoiled, or left unused. They also review whether all required precinct reports and ballot categories are included.
A ballot count isn't automatically the same as a candidate vote total. Voters can leave contests blank, and a ballot may contain an invalid vote in one contest while other votes qualify.
A difference between ballots counted and votes recorded in one race may reflect skipped contests. Compare like quantities before calling it a discrepancy.
Investigate differences and document corrections
A mismatch needs an explanation. Officials may review missing paperwork, compare reports, check a transcribed figure, or examine how a ballot batch was recorded.
An error on a public results page and an error in tabulation are different problems. We look for documentation identifying what happened and which record changed.
The canvass provides a structured opportunity to find and address problems. Its completion shouldn't be treated as proof that every earlier report was complete or correct.
How outstanding ballots enter the record
The canvass also accounts for eligible ballots absent from the first public tally. Their timing depends on law, processing requirements, and the work remaining in that jurisdiction.
We don't assume one ballot category always reports first or last. The useful question is which ballots remain in the election you're following.
Mail, military, and overseas ballots
Election workers follow rules for receiving, checking, processing, and counting mail ballots. States differ on when those steps can begin and which receipt deadlines apply.
Some mail votes appear in election-night totals. Others appear later. Military and overseas ballots can have additional timing requirements under applicable law.
A later batch can change a lead without changing previously counted votes. It can also lower a candidate's percentage while increasing that candidate's vote count, because the total number of reported votes has grown.
The election office's outstanding-ballot report helps explain that movement.
Provisional ballots require an eligibility decision
A provisional ballot preserves a voting opportunity when eligibility can't immediately be confirmed for a regular ballot. Officials then review the question under the applicable rules.
They may check registration, residence, identification requirements, or whether another ballot from the voter was already counted. A pending ballot hasn't yet been accepted or rejected.
Depending on jurisdiction and circumstances, it may count fully, count for certain contests, or be rejected. Partial counting means accepting eligible contest votes, not assigning fractions of a vote.
Eligible ballots must be counted regardless of whether they can change the winner. A comfortable margin doesn't end the required review.
Who reviews the record and certifies results
There isn't one nationwide arrangement for election administration. State law assigns duties to election officials, canvassing boards, and other authorities.
Local review and statewide certification can also be separate steps. A county's completed work doesn't necessarily mean every statewide contest has been certified.
Election officials assemble the supporting record
Election staff conduct much of the operational work. They process eligible ballots, reconcile records, review discrepancies, and prepare returns and supporting materials.
A canvassing board or another designated body may review those materials and take formal action. Membership, authority, meeting requirements, and division of responsibilities depend on jurisdiction.
For a claim about a board's decision, we check the agenda, minutes, recording, and adopted documents. Our guidance on checking claims against meeting records helps separate a member's comment from the body's formal action.
The discussion and the decision are different parts of the record.
Certification gives the results official status
Certification is the formal approval or attestation required by the applicable process. The EAC's glossary of election terms describes certification of official results as a written statement attesting to the accuracy of the accounting.
Which officer or board makes that statement varies. Certification follows the required review; a candidate's concession or a newsroom's call doesn't substitute for it.
Certified results can still be subject to recounts or legal proceedings where the law provides for them. Official status and the availability of further review are separate questions.
Canvasses, audits, and recounts have different jobs
These terms are often flattened into one idea. That makes the process harder to understand.
A canvass checks and reconciles the broader election record. An audit tests specified aspects of election administration or tabulation. A recount counts votes again in a contest under applicable rules.
Audits test the count through a defined method
A post-election tabulation audit may compare paper ballots with machine-reported results for selected ballots, precincts, or contests. The selection method and scope depend on the jurisdiction and audit type.
Some audits use statistical sampling. Others use a prescribed percentage or another statutory method. Audits may be integrated into the post-election process, but the sequence isn't identical everywhere.
We check what an audit examined before interpreting its findings. A statement about sampled ballots shouldn't be described as a hand count of every ballot cast.
The EAC's results and canvassing resources provide further guidance on these post-election procedures.
Recounts count contest votes again
A recount may be triggered by a close margin, requested by an eligible party, or ordered through another lawful process. Thresholds, deadlines, costs, and counting methods vary.
Some recounts use machines. Others involve hand counting or a combination of methods.
An election canvass isn't necessarily a universal hand recount of every ballot. Calling routine reconciliation a recount can falsely suggest that the entire election was counted twice by hand.
Read the procedure's scope, not just its label.
Why certification timelines differ
The official result requires more than a final upload. Officials need time to finish eligible-ballot processing, reconcile records, resolve discrepancies, and complete required reviews.
Those tasks operate within legal deadlines. There isn't a single national canvass period or certification date for all elections.
For a concrete state example, the California Secretary of State's official vote-counting explanation describes a 30-day county canvass period and statewide certification up to 38 days after the election. Those are California timelines, not instructions for officials elsewhere.
For a particular contest, check the calendar for that election. Separate the county deadline, any statewide deadline, and deadlines that apply to voters submitting information.
Time alone doesn't establish whether a count is proceeding properly. A delayed update needs context: what work remains, what deadline applies, and what the election office has reported.
A close race may receive more public attention, but counting obligations don't depend on suspense. Officials still must account for eligible votes when the likely outcome is clear.
When reporting on timing, we prefer the office's stated schedule to an assumption that every jurisdiction should finish together.
How to check a claim about changing totals
A screenshot can preserve a real number while losing its explanation. Before drawing a conclusion about a "flip," identify the source and the kind of change being claimed.
We follow three checks:
- Find the responsible election office's original results page. Confirm the election, contest, jurisdiction, timestamp, and status label. Determine whether the number describes votes, ballots received, ballots accepted, or precincts reporting.
- Look for the office's explanation of the update. Newly counted eligible ballots differ from a correction to an earlier report. Check which ballots were added, which figure changed, and whether officials published a notice or canvass record.
- Match the evidence to the claim. A changed lead, a changed percentage, a revised media projection, and certification are separate events. One doesn't establish the others.
Repeated coverage isn't independent confirmation. Our guide to tracing aggregated news to its source helps identify where a report began and whether later outlets checked it.
For a close contest, a countywide outstanding-ballot figure may be insufficient. Some ballots may not contain that race or qualify for counting in it.
The useful figure is the number of outstanding ballots that could contain valid votes in the contest. If that information isn't available, say what remains unknown.
Read the result with its record attached
An early tally can offer a dependable picture while required work continues. The canvass checks the accounting, and certification gives the result official status under the applicable rules.
We judge a changing number by its documented explanation, not by how sudden it looks on a screen.
Check the source, the timestamp, and the stage of review. Those details keep an early snapshot from being mistaken for the completed record.
