The short answer

Election-night totals are unofficial. After Election Day, officials finish counting eligible ballots, including provisional ones, then canvass and certify the results on deadlines each state sets. In Illinois, for example, the State Board of Elections must canvass statewide and congressional results within 31 days after the election, which this year means by Dec. 4.

Key facts

  • Results reported on election night are unofficial and preliminary; they may not include all ballots, haven't been canvassed and could change (CRS R46565, updated Oct. 19, 2026, checked Oct. 31, 2026). Source
  • The canvass aggregates and confirms every valid ballot cast and counted, including mail, military and overseas, early, Election Day and provisional ballots; certification is officials attesting that results are a true and accurate accounting of all votes cast (U.S. Election Assistance Commission, page dated July 30, 2026, checked Oct. 31, 2026). Source
  • Illinois county election authorities must validate and count provisional ballots within 14 calendar days of the election, then have 7 days for their final canvass (10 ILCS 5/18A-15, checked Oct. 31, 2026). Source
  • The Illinois State Board of Elections must canvass the votes for U.S. Senators, U.S. Representatives, state executive officers and other listed offices within 31 days after the election, and sooner if all returns are received (10 ILCS 5/22-7, checked Oct. 31, 2026). For the Nov. 3, 2026 election, 31 days is Dec. 4. Source
  • The State Board of Elections' meeting calendar lists Friday, Dec. 4, 2026, at 10 a.m. for the 'Proclamation of results of the November General Election' (checked Oct. 31, 2026). Source
  • In Illinois, a mail ballot postmarked by Election Day counts if it arrives before the provisional-ballot counting period closes (10 ILCS 5/19-8(c), checked Oct. 31, 2026). Source

Election-night totals are unofficial. After Election Day, officials finish counting eligible ballots, including provisional ones, then canvass and certify the results on deadlines each state sets. In Illinois, for example, the State Board of Elections must canvass statewide and congressional results within 31 days after the election, which this year means by Dec. 4.

Key facts - Election-night results are "unofficial and preliminary" and could change (CRS R46565, updated Oct. 19, 2026). - The canvass confirms every valid ballot, including mail, military and overseas, early, Election Day and provisional ballots (U.S. Election Assistance Commission, checked Oct. 31, 2026). - Illinois counties must finish validating and counting provisional ballots within 14 days of the election, by Nov. 17 this year (10 ILCS 5/18A-15). - The State Board of Elections must canvass within 31 days, by Dec. 4 (10 ILCS 5/22-7); its calendar lists a Dec. 4 meeting for the "Proclamation of results of the November General Election" (ISBE, checked Oct. 31, 2026).

The Nov. 3 midterms will produce a flood of numbers on election night. Those numbers are real counts, but they aren't the result. Every state runs the same basic sequence after the polls close: keep counting, check and reconcile everything in a canvass, then certify. What changes from state to state is the calendar and who signs off. This guide explains each step using federal sources, then walks through the actual 2026 dates in one state, Illinois, from its election code. For what's on the ballot in the first place, see our 2026 midterms explainer.

Why are election-night results unofficial?

Because counting isn't finished and nothing has been checked yet. The Congressional Research Service's Federal Election Results: Frequently Asked Questions (R46565, updated Oct. 19, 2026) says state- or territorial-level federal election results "are never official on election night." Totals that the media or election offices publish on election night "do not necessarily include all ballots," haven't gone through the canvass, and could change. CRS calls it "normal and expected" that final totals differ from election-night figures and that leads can change as more ballots are counted.

The U.S. Election Assistance Commission makes the same point on its results, canvass and certification page (dated July 30, 2026): even results showing "100% Precincts Reporting" are still unofficial. Race calls are a separate thing. The EAC notes that the media may project a winner, but "only election officials provide official election results."

What happens after the polls close?

Counting continues. CRS says the pace depends on choices each state makes: when voters can cast ballots early or by mail, when officials may start processing those ballots, and whether a mail ballot must arrive by Election Day or only be postmarked by then. Some states let officials process or even count mail ballots before Election Day; others bar counting until the polls close.

CRS also notes a ruling that affects mail-ballot timing this year. In Watson v. Republican National Committee (June 29, 2026), according to the report, the U.S. Supreme Court upheld a state law counting absentee ballots postmarked by Election Day and received up to five days later, holding that "nothing in the federal election-day statutes requires ballots to be received by election day." Whether a given state accepts late-arriving ballots still depends on that state's law.

Provisional ballots are also resolved in this window. They are set aside on Election Day until officials confirm the voter was eligible (see the FAQ below).

What is a canvass?

The canvass is the checking stage. In the EAC's words, it "aggregates and confirms every valid ballot cast and counted, including mail, uniformed and overseas citizen, early voting, Election Day, and provisional ballots." Officials reconcile the number of ballots cast against the number of voters who voted, so the totals add up.

CRS lists typical steps: reconciling ballots issued with ballots cast; duplicating damaged ballots a scanner can't read and documenting it; resolving signature questions and voter-intent questions; and confirming that procedures were followed. CRS says those steps may be repeated as results are consolidated at higher levels, such as precinct, county and state, and that most states give observers or the media access to certain post-election procedures. The EAC adds that most states require a post-election audit to verify that voting equipment counted votes correctly; timing and methods differ by state.

When are results certified?

After the canvass, on a date each state sets. The EAC defines certification as election officials "attesting that the election results are a true and accurate accounting of all votes cast." Who does it varies: the EAC says local results may be certified by a board or a single official such as a county auditor or municipal clerk, and state results by a secretary of state, a governor, the legislature, an appointed director or a multi-member board.

There's no single national date. CRS, citing the National Conference of State Legislatures, says state certification deadlines range from specific times, such as "5 p.m. the 17th day after the election," to open-ended ones such as "Upon completion of the state ballot counting review." The National Association of Secretaries of State keeps a state-by-state summary of canvassing timeframes and recount thresholds, last updated October 2024; it's useful for comparison, but check your own state's current law and election calendar for 2026 dates.

Recounts can push the timeline. The EAC gives two examples: New Hampshire law sets state certification after the recount deadline expires, and in West Virginia counties must certify within 30 days of the election or, if there's a recount, within 30 days of finishing it. Certification covers whatever districts are on the ballot; for the congressional maps some states redrew before this election, see our redistricting explainer.

How does Illinois certify its results?

Illinois spreads the work across its county clerks and municipal election boards and the State Board of Elections, and its election code sets each deadline. Counting from Election Day, Tuesday, Nov. 3, 2026, the statutes produce this calendar (dates computed by The Whole Read from the statute text, checked Oct. 31, 2026):

Step What the law says 2026 date
Mail ballots counted Results of processing mail ballots generally may not be counted until after 7 p.m. on Election Day (10 ILCS 5/19-8(b)) Nov. 3
Late-arriving mail ballots A mail ballot postmarked by Election Day counts if it arrives before the provisional-ballot counting period closes (19-8(c)) through Nov. 17
Provisional ballots County authorities complete validation and counting "within 14 calendar days of the day of the election" (10 ILCS 5/18A-15(a)) by Nov. 17
Rejected mail ballots A voter whose mail ballot was rejected may appear before the election authority "on or before the 14th day after the election" to show cause why it should count (19-8(g-5)) by Nov. 17
County canvass 7 days after provisional counting for the final canvass (18A-15(a)); county election authorities make abstracts of votes within 21 days (10 ILCS 5/22-1) by Nov. 24
State canvass The State Board of Elections canvasses within 31 days, "and sooner if all the returns are received" (10 ILCS 5/22-7) by Dec. 4

The state canvass under 10 ILCS 5/22-7 covers U.S. Senators and Representatives in Congress, state executive officers, Supreme Court, Appellate and Circuit Court judges, state legislators, and certain multi-county offices, plus statewide ballot questions. The candidates with the most votes are "declared duly elected," a tie is decided by lot, and the Governor issues each winner a certificate of election and proclaims the result. Section 18A-15 sets the same 31-day window for the board's "final canvass of the vote for all public offices."

The board's own meeting calendar matches the statute: it lists Friday, Dec. 4, 2026, at 10 a.m. (Chicago and Springfield) for the "Proclamation of results of the November General Election." Meeting dates can change, so check the calendar closer to the date. Note that Illinois law uses the words "canvass" and "proclamation"; the certificate of election itself comes from the Governor.

How do we handle claims about the count?

Claims about vote counts tend to spread fastest in the weeks between election night and certification. When The Whole Read's Plumb Line feature checks such a claim, it rates it against official sources like the ones linked here; our methodology page explains how. This guide doesn't rate any claim.

Frequently asked questions

What is a provisional ballot? It's a ballot set aside until officials can confirm the voter was eligible to cast it. Illinois law lists when a voter gets one, for example when the voter's name isn't on the precinct list or a challenge to the voter is sustained (10 ILCS 5/18A-5). CRS R46565, quoting the EAC, says that during the canvass officials "determine whether to count provisional ballots."

Why do some states take weeks to finish? CRS R46565 says the timeline depends on when states let voters cast ballots, when officials may start processing and counting them, and whether mail ballots must arrive by Election Day or only be postmarked by then. Certification deadlines are set by state law and vary widely, as NASS's state-by-state summary shows.

When does Illinois certify its 2026 results? The State Board of Elections must canvass statewide and congressional results within 31 days after the Nov. 3 election (10 ILCS 5/22-7), which is Dec. 4. Its calendar lists a Dec. 4 meeting for the proclamation of results.

Is certification the same as a recount? No. CRS R46565 describes a recount as retabulating ballots to make sure the certified count was accurate, though in some places a recount can happen before certification. Each state's law sets whether and when recounts happen.

Can news organizations' race calls make results official? No. The EAC says the media may call a projected winner, but "only election officials provide official election results."
