ФНС Проверка (Federal Tax Service Check) provides API access to the Russian Federal Tax Service (ФНС) database for verifying legal entities and individual entrepreneurs by their INN (taxpayer number) or OGRN (state registration number).
With the FNS Check integration in AACFlow, you can:
- Check by INN: Retrieve company details (name, address, status, management) by INN
- Check by OGRN: Look up an organization using its OGRN registration number
This integration is essential for counterparty due diligence, KYC, and onboarding automation in Russian business workflows.
