Key:operator:ref:ogrn

А tag operator:ref:ogrn=* is used to indicate an organization's OGRN.

In the Russian Federation, the PSRN (Primary State Registration Number) is assigned to a legal entity upon its creation as the registration number in the state register.

A Primary State Registration Number (PSRN), known in Russia as OGRN (for legal entities) or OGRNIP (for individual entrepreneurs), is a unique, long numerical identifier assigned by the state to legally register businesses and individuals for business activities, serving as their fundamental identification in state registers like the Unified State Register of Legal Entities (EGRUL) in bank's and for tax purposes. It's a key part of a company's official documentation, alongside the INN (Taxpayer Identification Number).

Each Russian company has its unique tax number about all taxes and duties. OGRN is used in the Register as the number of registration files of a company. As a proof of its OGRN, a company receives the certificate with OGRN issued by the state registration body.

This number can be obtained from the organization's website, sign, documents, and other sources.
