ogrn.su

OGRN.su is a Russian-language online service for checking legal entities and individual entrepreneurs using open data from the Federal Tax Service of Russia. It helps users find business information by entering a taxpayer identification number (INN) or a state registration number (OGRN or OGRNIP). Search results bring key details together in one profile, including an organization’s or entrepreneur’s status, registration date, business activity, and region.

The service describes its checks as free and says its database covers 6.7 million organizations and individual entrepreneurs from the tax authority’s register. The register is updated monthly, with the Federal Tax Service identified as the source of the data. OGRN.su is intended to support due diligence before business transactions and make basic counterparty checks more accessible.

Beyond its search tool, the website offers publications with analytical material about counterparty checks and tax registers, alongside news about legislative and registry changes relevant to business verification. It also includes sections for entrepreneurs and information about the small and medium-sized enterprise register.
