BORME stands for Boletín Oficial del Registro Mercantil, the Official Gazette of the Commercial Register. It is the official journal in which Spain publishes the legally prescribed particulars of acts registered by the commercial registries, concerning companies and other registered persons and entities, and the notices that the law requires to be made public: incorporations, appointments of directors, changes of address, capital increases, mergers, dissolutions, insolvency.

It is edited by the state gazette agency, the Agencia Estatal Boletín Oficial del Estado, and published on boe.es. Reading it is free, and its electronic edition has been the official one since 2009. It is published in Spanish.

When it is published

BORME is published Monday to Friday, except on public holidays observed in Madrid. There was no issue on Saturday 10 or Monday 12 October 2026, Spain's national day, for example. What is registered on those days appears in the following issues.

Days, sometimes weeks, usually pass between the entry in the registry and the publication. In registered-act notices, the date of the registry entry normally appears in brackets after the registry particulars, so you can tell when an act was registered and not only when it was published.

The two sections

Section I, "Empresarios". It has two parts:

Section II, "Anuncios y avisos legales" (part C): announcements and notices that the law requires, distinct from the publication of registered acts, such as calls to general meetings, merger and demerger plans, capital reductions and increases, dissolutions, transformations and final liquidation balance sheets. Each announcement is published separately, grouped by announcement type and alphabetically by company name within each group.

Which acts appear among the registered acts

Notices use recurring headings, although their presentation varies. These are the most common, with their meaning:

How to read a notice

A registered-act notice looks like this. The example is invented, but it follows the real format:

412345 - EJEMPLO DE SERVICIOS SL.
Constitución. Objeto social: Consultoría informática. Domicilio: C/ MAYOR 1
(MADRID). Capital: 3.000,00 Euros.
Nombramientos. Adm. Unico: GARCIA LOPEZ MARIA.
Datos registrales. T 45000 , F 101, S 8, H M 800000, I/A 1 (06.10.26).

Line by line:

The sheet is what identifies a company within its registry: the name can change, the sheet does not. The tax number (NIF), on the other hand, is not supplied systematically, although some notices include it.

How to find what was published about one company

It depends on the section:

If you only need to know whether a company is registered and who is recorded as representing it through its governing body, the quickest route is not BORME but the registrars' free directory, explained in our guide to the Spanish company register.

What BORME does not contain

Where BORMEAPI fits

BORMEAPI reads the registered-act notices published since 2009, turns each heading and abbreviation into a typed event, and groups the events by company. Event types are expressed in English. What in the gazette is a search through thousands of PDFs published over the years becomes one request:

You can also browse, without a key, the weekly summary of what was published in each province on our province pages, which are in Spanish. The free key allows 50 requests a day for the events published in the last seven days; the full archive since 2009 and change alerts are in the paid plans. Every event keeps the reference to the official notice it came from.
