How the Spanish Company Register (Registro Mercantil & BORME) Works

In Spain, commercial companies (such as Sociedad Limitada — S.L. and Sociedad Anónima — S.A.) are legally required to register their incorporation, share capital, registered address, directors (administradores), powers of attorney (apoderados), annual accounts, and insolvency or dissolution acts in their provincial Registro Mercantil (Mercantile Registry).

Every official act recorded by the 52 provincial Mercantile Registries is published daily in the Boletín Oficial del Registro Mercantil (BORME) by the Spanish State Agency BOE (Agencia Estatal Boletín Oficial del Estado). OpenMercantil indexes and structures this official public gazette so you can search any Spanish company by name, tax number, province, or industry sector (CNAE / NACE Rev. 2).

How to Verify a Spanish Company Tax ID (CIF / NIF)

F + 7 digits + control: Cooperative Society (Sociedad Cooperativa).
