Fix SEDOL | Calculate SEDOL Check Digit

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. If you would like to apply for a SEDOL code and need assistance with creating or generating and obtaining a SEDOL number please reach out to us for application assistance needs by email: isin@isin.org

A SEDOL consists of two parts:

• A six-character alphanumeric code
• A single check digit.

For example: B29VX20 (Invesco)

On this page, you can either:

• enter a SEDOL without the check digit, or:
• enter a full SEDOL you would like to fix.

In both cases, a correct SEDOL will be calculated for you, if possible. Note that the result can be a non-existing SEDOL, since it is being calculated!

Disclaimers:

• Note that the result can be a non-existing number. Since it is being calculated by an algorithm, even if a number like an ISIN or SEDOL shows up it may not exist – it’s just the algorithm showing what could exists.
• This tool is an algorithm. Just because you enter a code does not mean it is an active number or a created number. Even if a code is generated it does not indicate that the code is active or was created.
• The term “SEDOL: refers to the national number for securities issued for UK and Ireland securities which is seven digits in length.
