What INN / OGRN Validator does
local-first
INN / OGRN Validator checks Russian taxpayer and registration numbers locally. Paste an INN, OGRN, or OGRNIP to detect the number type, normalize digits, compare the expected control digit with the actual one, and review tax office, year, and region parts where the format supports them.
