REGON - Statistical number of an economy entity (PL-REGON)


A unique number assigned to national economic entities, and to the local units of these entities in the national official register of national economy entities, REGON. The identifier provides no implicit or explicit information on the features of an entity.

Every organization receives REGON number during the registration phase.

Looking at REGON/NIP relations: most often all organizations having NIP (PL-NIP) will have REGON (PL-REGON) and vice-versa.

One of a few exceptions are, for example, schools that will have REGON numbers (for statistical purposes), but they are not required to have NIP tax id number (because they are executing municipalities' budgets).
