ISIN to LEI Match


International Securities Identification Number (ISIN)
An International Securities Identification Number (ISIN) uniquely identifies a security. Its structure is defined in ISO 6166. Securities for which ISINs are issued include bonds, notes, certificates of deposit, commercial paper, stocks and warrants. The ISIN code is a 12-character alpha-numerical code that does not contain information characterizing financial instruments but serves for uniform identification of a security at trading and settlement.

Are you looking to:
- map your ISINs to LEIs?
- map your ISINs to MFIs?
- enrich your database with official LEI data?
- verify the mappings that you have created in-house?
In this case, it is really simple! Just send your relevant ISIN data set to and we will check your data for ISINLEI maps.

We not only have built sophisticated tools to match the name of the Issuer that has issued the ISIN with the registered legal name of the LEI or MFI to provide a high level of confidence that that ISIN to LEI or MFI match is correct. More importantly, we have networked the ISIN to LEI and ISIN to MFI match and thereby are able to verify the match with funding officials working for the relevant issuer. This provides an added level of certainty that the ISIN to LEI or ISIN to MFI match is correct.
