What is an ISIN or SEDOL number?
ISIN and SEDOL numbers are used to uniquely identify investments.
ISIN, which stands for ‘International Securities Identification Number’, is an international standard. Every ISIN is 12 digits long, is alphanumeric, and begins with two letters representing the country of registration. (For example, Vodafone’s ISIN is GB00BH4HKS39).
SEDOL, which stands for ‘Stock Exchange Daily Official List’, is a seven-character identification code. Many investments are listed on multiple exchanges – a SEDOL is useful because it tells you not only what the investment is, but which listing you’re 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).
