What is an ISIN or SEDOL number?
ISIN and SEDOL codes are used to uniquely identify investments.
The International Securities Identification Number (ISIN) is an international standard. It has 12 digits and is alphanumeric, beginning with two letters representing the country of registration. (For example, Vodafone’s ISIN is GB00BH4HKS39).
The stock exchange daily official list (SEDOL) is a seven-character identification code. Many investments are listed on multiple exchanges, so the SEDOL tells us not only what the security is, but which listing we are looking at. If a security is listed on five different exchanges, it will have five different SEDOL codes. (For example, Vodafone’s London SEDOL is BH4HKS3).
