Where the information comes from.

Public and official records

Where the data comes from

Drawing dates and winning numbers come primarily from New York State Open Data, which publishes government-operated datasets for the multi-state games. Work The Numbers currently uses its Powerball results dataset and Mega Millions results dataset.

The Multi-State Lottery Association (MUSL), the organization that helps administer the games, provides an additional record for recent winning numbers and available jackpot information.

Official game rules and odds

Official Powerball and Mega Millions publications are used for current game rules, number pools, odds, prize information, and effective dates.

These sources do not always publish every field at the same time. A result can appear without a jackpot value or other optional detail, and an unavailable value is not estimated or filled in.

What is compared

How results are checked

For a drawing, Work The Numbers checks the game, drawing date, five main numbers, bonus ball, and multiplier when one is published. It also checks that the number of balls and their values fit the supported game record.

When comparable records are available from more than one source, those drawing details are compared. Jackpot figures are handled separately because advertised amounts and timing can differ without changing the winning numbers.

A result can also be confirmed from a single public record when that source is designated as authoritative for the drawing. The page for each drawing shows the result’s current status and the available source links.

What each label means

Understanding result statuses

Provisional

The latest available result has been published, but verification is still in progress. It may change if a newer or more authoritative record becomes available.

Confirmed

The result is supported by an authoritative public record or by matching records from multiple sources.

Corrected

The result was updated after its initial publication. The current page reflects the newer information while the label makes the change clear.

Void

The record was invalidated and should not be treated as a valid drawing result. It may remain visible only to make the historical record understandable.

A status describes the source evidence available to the site. It does not mean that a Work The Numbers editor personally reviewed every drawing. Published studies state their inclusion policy and sample on the Research Center.

Differences between records

When sources disagree

If source records disagree about the drawing date, numbers, bonus ball, or multiplier, Work The Numbers does not describe the result as confirmed merely because several providers are present. The result remains provisional while the difference is reviewed through later source updates.

A newer record or a record from the more authoritative source can supersede an earlier one. Later agreement can move a result to confirmed, and a published correction remains visibly labeled as corrected when that status applies.

Publication is not instantaneous

Timing and known limitations

Recently published results may appear as provisional before all expected source information is available. Updates can be delayed by the source organization’s publication schedule, service outages, rate limits, or a temporary problem with a particular record. Work The Numbers does not promise real-time results.

Historical coverage can contain gaps, and older drawings may have used different number pools, prize rules, or multiplier formats. Jackpot amounts can also be estimates or can change independently of the winning numbers. Analytical pages account for supported rule eras where described, but no third-party data service can guarantee that every public record is complete or error-free.

Always verify a ticket, prize amount, claim deadline, and claim procedure through the official lottery that applies to the ticket. Work The Numbers is an informational service, not a ticket-checking or prize-claim authority.

Facts, calculations, and interpretation

How a record becomes a published page

Winning numbers and drawing dates are source facts. Structural measures, historical comparisons, and rankings are derived by application code from the stored record. Plain-language summaries translate those derived values without changing them or making prediction claims.

Individual drawing pages must pass a publication-value check before entering the sitemap: supported status, valid rule-era number structure, stored source provenance, and draw-specific context. A record that fails remains available when transparency requires it, but is marked not for search indexing until the missing requirement is resolved.

Automated tests cover validation rules and representative older formats. Product changes are also sampled on current and historical pages. A reported factual problem is reviewed against its stored provenance and applicable public source; supported corrections replace the canonical fact while retaining a visible corrected status where appropriate.
