CFI and FISN Codes

Financial markets have been creating a large number of instruments, most frequently shares bonds and collective investment vehicles; however, there are derivatives and currencies among these instruments also. The Classification of Financial Instruments, i.e. the CFI code was created based on the ISO 10962 standard and the Financial Instrument Short Name, i.e. the FISN code was created based on the ISO 18774 standard for the clear grouping of instruments.

The CFI and FISN codes of all instruments are generated by the members of ANNA (Association of National Numbering Agency), in Hungary by KELER. These codes are no need to be required as KELER automatically generates them. KELER creates CFI and FISN codes of instruments issued in Hungary.

The CFI code is generated in same time as the ISIN code, in case of dematerialized securities the FISN code is issued after the generation of instruments and in case of printed securities the FISN code is generated in same time as the code.

Please note that ISIN code of the instrument is constant but the CFI and FISN codes may change whit the modification of the instrument details.
