What the BORME is

The BORME (Boletín Oficial del Registro Mercantil) is the official gazette of Spain's company registers. The BOE, the state agency that publishes Spain's official journals, issues it every working day. Its Section A lists the acts the provincial Registros Mercantiles have just registered: a company is incorporated, appoints or removes officers, moves its registered office, changes its capital, is dissolved or closes.

The BORME names each company by its name and its sheet (hoja) in the Registro Mercantil, for example B-643957 for a company registered in Barcelona.

Which acts Fuentio reads

Fuentio reads the Section A acts published since 6 October 2025: incorporations, appointments and removals, address changes, capital changes, dissolutions, extinctions and more. Officers' names and roles are kept as published, and each act links to its page on the BOE.

Two limits to know:

  • Spain starts on 6 October 2025. A company with no act since then isn't in Fuentio. For Spain, "not found" means "no act since that date", never "this company doesn't exist".
  • NIF and CIF numbers aren't supported. Search by name, then use the sheet.

Status comes from the acts

A Spanish status is never guessed. A dissolution or an extinction act sets it; when there is none, the status is unknown.

A real example from our snapshot: QILOVATIO ENERGIA IBERIA S.L., incorporated on 28 October 2025. Its acts:

So its status reads:

QILOVATIO ENERGIA IBERIA S.L. (ES, Registro Mercantil sheet (hoja) B-643957) is dissolved as of 2026-05-15, source: BORME — Boletín Oficial del Registro Mercantil (Sección A).

Find a company and read its acts

Search by name from an agent (2 units):

search_companies({"country": "ES", "query": "QILOVATIO"})

or with curl:

curl "https://api.fuentio.com/v1/companies/search?country=ES&q=qilovatio"

Then look the company up by its sheet (1 unit). Its acts come with the record:

lookup_company({"country": "ES", "identifier": "B-643957"})
curl https://api.fuentio.com/v1/companies/ES/B-643957
