IBAN formats by country[edit]
This table summarises the IBAN formats by country:[1]
The kk after the two-character ISO country code represents the check digits calculated from the rest of the IBAN characters. If it is a constant for the country concerned, this will be stated in the Comments column. This happens where the BBAN has its own check digits that use the same algorithm as the IBAN check digits
The BBAN format column shows the format of the BBAN part of an IBAN in terms of upper case alpha characters (A–Z) denoted by "a", numeric characters (0–9) denoted by "n" and mixed case alphanumeric characters (a–z, A–Z, 0–9) denoted by "c". For example, the Bulgarian BBAN (4a,6n,8c) consists of 4 alpha characters, followed by 6 numeric characters, then by 8 mixed-case alpha-numeric characters
Descriptions in the Comments field have been standardised with country specific names in brackets. The format of the various fields can be deduced from the BBAN field
