A SEDOL (Stock Exchange Daily Official List) is a 7-character alphanumeric code that serves as the National Securities Identifying Number for all securities issued in Ireland and the United Kingdom.

The SEDOL code is structured as follows:
• A six-character alphanumeric code
• One check digit

Example: 2379504 (NVIDIA)

Use this tool to match a SEDOL with its corresponding ISIN (International Securities Identification Number). Select the relevant country and enter the SEDOL. If the ISIN exists in our database, it will be displayed. If not, the system will generate a valid ISIN format for you, if possible.
Please note: The calculated ISIN may not correspond to an actual issued security, as it is algorithmically generated when not found in the database.
