About the service

ISIN is the recognised global standard and a unique identifier of financial instruments. It is comprised of twelve characters including: 

  • a prefix, which is the alpha-2 country code specified in ISO 3166;
  • the basic number – nine alphanumeric characters;
  • a check digit calculated using the modulus 10 formula under ISO 6166.


Participants of the global capital market using ISIN codes may not be able to identify the type of instrument quickly, which is why a single standard is used for the classification of financial instruments: CFI and FISN.

is the classification code of financial instruments. It is composed of six alphabetic characters. The first character stands for the category of financial instruments, the second character for the group in the category, and the last four characters for the key attributes of the group.
