MFI ID (Monetary Financial Institution Identifier) is a code, unique to each institution in the MFI list provided by ECB (European Central Bank). MFI ID is hence applicable to MFIs resident in the European Union.
The code is alphanumerical, with the first two digits representing the two-digit ISO code for the country of residence of the MFI and the remaining number of digits (no limit has been specified) is any combination of alphanumerical characters.
