Reporting a wrong number
The fastest way is the “Report an error” button under any result: it opens an email that already includes your inputs. Please add:
- Which number looks wrong, and what you expected
- A link to the official source — a state lottery page, a state tax agency or the IRS
We check every report against the source and record corrections in the methodology.
What we cannot help with
We cannot give personal tax or financial advice, check tickets or answer questions about claiming a prize. For those, contact your state lottery or a tax professional.
