Overview

The Boletín Oficial del Registro Mercantil (BORME) is Spain’s official business registry bulletin, published daily by the Registro Mercantil Central (RMC). It contains crucial information about business activities across Spain, including newly created companies, dissolved entities, and mandatory corporate filings.
BORME is the authoritative source for tracking business registry changes in Spain, making it essential for corporate intelligence, due diligence, and compliance.
BORME serves as the official public record of all mercantile registry activities in Spain. Companies are legally required to publish certain corporate events and changes in BORME.

Electronic Publication Law

Since 2009, BORME has been published in electronic format following the approval of Royal Decree 1828/2008. This law established that:
  • Electronic BORMEs have the same legal validity as paper versions
  • Publications must be made daily in digital format
  • All registry changes must be publicly accessible
The electronic format requirement has made it possible to programmatically access business registry data, though some limitations remain in the available formats.

Accessing BORME

Official BORMEs are available at: Official Source: https://boe.es/diario_borme/
While BORME is published electronically, not all data is available in structured formats like XML or JSON. The most detailed information is only available in PDF files, which is why bormeparser was created to extract structured data from these PDFs.

Data Format Limitations

Due to agreements between the Spanish government and the Mercantile Register, the most valuable business data is only published in PDF format. This means:
  • XML files contain metadata and document structure but not detailed company information
  • PDF files contain the complete detailed data but require parsing
  • HTML files are available only for Section C
This limitation is why bormeparser exists - to extract structured, machine-readable data from BORME PDF files.
