The purpose of the restriction is to reduce the chances that the resulting identifier may be identical to an ISIN string. (Strictly speaking, a duplicate is not a problem as the strings designate different things, but care has been taken to reduce ambiguity.) The way that ISIN is constructed is that the first two characters correspond to the country of issuance. The third character, depending on the issuing organization, is typically a numeral. However, in the case of the United Kingdom, the letter "G" is assigned. As we are using the letter "G" as our third character (see below), the only combinations that may come up within ISIN that only incorporates consonants are BSG (Bahamas), BMG (Bermuda), GGG (Guernsey), GBG (United Kingdom) and VGG (British Virgin Islands). The reason for this is that the United Kingdom issues ISIN numbers for entities within its broader jurisdiction.
Character 3:
- The upper case letter G (for "global")
Characters 4 – 11:
- Any combination of upper case consonants and the numerals 0 – 9
Character 12:
- A check digit (0 – 9) which is calculated as follows:
Letters are converted to integers using a letter to integer look-up table provided in section 7.2.1 of the specification. Using the first 11 characters and beginning at the last character, map the character to its specific integer value from the look-up table, if the character is already a digit, use that value. Then, working right to left, multiply every second integer by two. Next, separate numbers greater than 10 into two separate digits (e.g., 57 becomes 5 and 7) add up all the integer values, each less than 10 now. Finally, subtract that summed value from the next higher integer ending in zero (e.g., If the summed value is 72, then 80 is the next higher integer ending in 0, and the check digit is 8). If the summed value of the digits is a number ending in zero, then the check digit is also zero. This process is similar to other financial instrument identifier check digit calculations but specifically chosen to reduce the chances of other schemes from validating versus this FIGI scheme.
=== Issuance === Unique FIGIs are published by Bloomberg L.P. and datasets are both searchable and available for download via the Bloomberg OpenFIGI website. FIGIs are never reused and once issued, represent an instrument in perpetuity. An instrument's FIGI never changes as a result of any corporate action. Any interested parties may request access to the bulk and individual lookup facilities, regardless of any existing relationship with Bloomberg L.P. or lack thereof. FIGIs are assigned to unique financial instruments on a proactive basis. Where a FIGI has not been assigned for any reason, a request can be submitted to have an identifier assigned, as long as the request is in line with the standard and stated assignment rules. FIGIs can often be mapped to other unique identifiers, such as equity and index option ticker symbols.
