Finding SEDOL and ISIN Identifiers for UK Funds
Summary
The question concerns matching SEDOL and ISIN identifiers for UK unit trusts and open-ended investment companies. The response offers two practical lookup routes: use a Bloomberg terminal if available, or search the fund issuer’s materials when the issuer name is known, since issuers often publish their reference identifiers.
This is a short operational pointer rather than a description of an identifier database, a mapping algorithm, or a verified source of complete coverage. It does not explain how to automate lookups, resolve multiple share classes, or confirm that two identifiers refer to the same product. The suggestions can help with an individual instrument search, but users handling larger datasets would need a structured reference-data provider and a separate validation process.
Key ideas
- A Bloomberg terminal is suggested as a source for looking up SEDOL and ISIN associations.
- An issuer’s website may list reference identifiers when the issuer is known.
- The response gives manual lookup suggestions rather than an automated mapping method.
- Identifier matches should be checked carefully when products or share classes may differ.

# How do I find the mappings between sedol and isin codes? # How do I find the mappings between sedol and isin codes? I am looking at data for Unit Trusts and OEICs in the UK. They are identified by SEDOL or ISIN codes. Given an SEDOL, how can I find the ISIN associated with the same product? And given an ISIN, how can I find the associated SEDOL? ## Answer by Philipp (score 2) https://quant.stackexchange.com/a/14273 Options: - bloomberg terminal (if you have one or someone else at work does) - Do you have the issuer names - could look around their websites where they typically list all reference names!
