Useful things to include
If a result looks wrong, send the business registration number you checked and what you expected to see. Results come directly from the National Tax Service, so a mismatch is usually either a data synchronisation delay or a bug in how this site interprets the response — both are worth knowing about.
This site cannot change registration records, correct tax office data, or intervene in a dispute with a supplier. For anything concerning your own registration, contact the National Tax Service directly.
