How to Convert SEDOL to ISIN

Converting between SEDOL and ISIN identifiers is essential for cross-border trading and compliance. Here's what you need to know:

What is a SEDOL?

SEDOL is a 7-character code used to identify securities on the London Stock Exchange and other UK/Irish exchanges.

What is a ISIN?

The ISIN is the international standard for identifying securities worldwide. It consists of a 2-letter country code, 9 alphanumeric characters, and a check digit.

How the Conversion Works

To convert a SEDOL to an ISIN, prepend the country code "GB00" and append a check digit calculated using the ISIN modified-Luhn algorithm (e.g. BH4HKS3 → GB00BH4HKS39). Most UK-listed securities follow this pattern.
