Some facts#

  • IBAN (International Bank Account Number) is a standardized method of numbering bank accounts.
  • The IBAN standard defines only general scheme allowing validation and recognition of the region where the account is located.
  • Each IBAN number consists of three constant parts:
    • country code - two-letter code defining the region in which the account is located (e.g. PL for accounts in Poland),
    • checksum - two-digit number calculated on the basis of other digits, this part allows checking whether the given IBAN number is correct or not,
    • regional part - this is part specific for a given region, both its length and the meaning of particular digits depend on local standards agreed in a given country (e.g. in Poland this part consists of 24 digits containing the national bank code, branch code, additional checksum digit and internal bank account number).
  • To check if the given IBAN number is correct, the following validation algorithm is used:
    • ignore whitespaces (spaces, tabs),
    • check if the length of the number matches the standard in the given region (basing on the country code),
    • move the first 4 characters to the end of the number,
    • replace letters by two-digit numbers according to the below rule:
      • A → 10,
      • B → 11,
      • C → 12,
      • etc.
    • treat the obtained digits as one number and calculate its remainder of division by 97,
    • IBAN is correct if the remainder of the division is 1, otherwise the number is invalid.
