How World Lottery Map verifies results
Our official-source, validation, deduplication and correction workflow in plain language.
Official sources come first
We use Donghaeng Lottery for Korea, Powerball for the United States and Mizuho Bank for Japan. Predictions and user reports do not establish a result.
Draw identifiers prevent duplicates
The game, draw identifier, date and expected number count are checked before storage. A repeated draw updates the existing record rather than creating a duplicate.
Corrections follow the source
When a discrepancy is found, we compare the record with the official publication and correct it. Readers can report a draw and its supporting source through our correction channel.
