About the Concatenated File

The Global Legal Entity Identifier Foundation (GLEIF) publishes a daily updated Concatenated File which includes:

  • All current Legal Entity Identifiers (LEIs) globally.
  • All related LEI reference data (LE-RD).

As its name indicates, it is a concatenation of all LEI records in the LEI data files published by all LEI issuers worldwide, provided in one central file, without changes.

LEI issuers – also referred to as Local Operating Units (LOUs) – supply registration, renewal and other services, and act as the primary interface for legal entities wishing to obtain an LEI.

GLEIF offers this unique service free of charge to any interested user, but please take note of the LEI Data Terms of Use.

The GLEIF Concatenated Files are available on this GLEIF Website page: LEI Download.

All files are provided as XML data in ZIP file format.

For full detailed information about the Concatenated File, including how to download, use and interpret the files, please read the 'GLEIF Concatenated File Specification and User Manual', which is available for download below.
