ISIN numbers act like serial numbers. They're governed by the International Organisation for Standardisation (ISO) but individually issued by the National Numbering Agency (NNA) that operates in the country where the security is issued. For instance, in the UK ISIN numbers are issued by London Stock Exchange PLC.
The structure of ISINs is expressed through ISO 6166:
- two alphabetic characters – representing the issuing company
- nine alphanumeric characters – the National Securities Identifying Number
- one numerical check digit
ISINs were first established in 1981 but weren’t widely accepted until recommended by the G30 countries in 1989. They were later endorsed by the International Organisation for Standardisation (ISO) and the ISO 6166 standard adopted.
If countries already had national numbering schemes, these were incorporated in the ISIN. In 2004 the European Union included ISIN as an authorised instrument identifier when they made this mandatory part of some regulatory reports.
