CFI and FISN Retrieval
Due to an increasing number of queries about how to obtain CFI and FISN codes for issued ISINs (both UK and Non-UK ISINs). Please see below instructions on how you can retrieve this data independently.
For UK ISINs
For active UK ISINs (GB, JE, GG, IM ISIN prefixes) please register for a free UnaVista account at www.sedol.co.uk where you will be able to search with the UK ISIN on our website and retrieve the corresponding CFI & FISN code for the security.
For Non UK ISINs
For Non-UK ISIN codes, please visit the ANNA ISIN Lookup Service. This service is free of charge and provides descriptive elements as outlined in ISO 6166 Standard (ISIN) as well as the classification codes (CFI) and description codes (FISN) for financial instruments.
The National Numbering Agency (NNA) who issued the ISIN code would be responsible for assigning the CFI and FISN also.
You can search by ISIN Prefix (ISO Column) on the ANNA website in order to determine who is the National Numbering Agency is for the ISIN.
