Check digits are computed with ISO/IEC 7064 MOD 97-10 — move the first four characters to the end, turn letters into numbers (A = 10 … Z = 35), and the result leaves a remainder of 1 when divided by 97. Bank codes used: DE 8-digit Bankleitzahl 37040044. TEST VALUES ONLY. IBAN has no reserved test range — unlike the 07700 900000–900999 block Ofcom keeps for drama — so these combine the bank and branch codes from each country’s published example IBAN with a seeded-random account number. They are format-valid and will pass a mod-97 validator; they are not accounts, they cannot receive money, and a bank will reject a transfer addressed to one.

Each country has exactly one IBAN length, set by the BBAN format it registered. Countries whose BBAN carries its own national check character are left out on purpose.

One IBAN per line. Duplicates are filtered out, so every row is distinct.

IBANs are traditionally written in groups of four for people to read and transmitted without spaces between systems. Both forms are the same IBAN.

The same seed always returns the same IBANs, so a shared link shows what you saw.

Über Test-IBANs

Before IBAN, sending money across a border was close to guesswork. Every country had grown its own way of naming an account — sort codes in Britain and Ireland, the Bankleitzahl in Germany, the RIB in France — and the formats had nothing in common, so the routing information a payment needed often went missing altogether. The codes banks exchanged under ISO 9362, the BIC or SWIFT code, carry no check digits at all, which meant a mistyped account number could not be caught before the money moved. Payments were delayed or returned, repairs were done by hand, and the cost came back to the banks and their customers.

ISO published a first answer, ISO 13616:1997. The European Committee for Banking Standards judged it too permissive to work and produced a slimmed-down version: upper-case letters only, and one fixed IBAN length per country. That version prevailed. ISO 13616:1997 was withdrawn in favour of ISO 13616:2003, the standard was split into two parts in 2007 — with part 2 naming SWIFT as the registration authority that maintains the IBAN Registry — and the current edition is ISO 13616:2020.

What makes the format work is a check-digit scheme borrowed from ISO/IEC 7064:2003, MOD 97-10. Move the first four characters to the back, replace every letter with a number from 10 to 35, read the result as a single integer, and divide by 97: a correct IBAN always leaves a remainder of 1. That one step is guaranteed to catch any character omitted, duplicated or mistyped, and any transposition of two characters.

European regulation did the rest. Regulation (EU) No 260/2012 set the technical and business requirements for euro credit transfers and direct debits, and in February 2014 the SEPA credit transfer scheme replaced the national schemes it had run alongside since 2008. Adoption spread well past the EU: by December 2024, 89 countries were using IBAN. The United States and Canada are not among them, which is why a payment there still needs an ABA routing or transit number.

Wichtige Eigenschaften

  • An IBAN is at most 34 characters: a two-letter ISO 3166-1 country code, two check digits, then a Basic Bank Account Number of up to 30 country-specific alphanumeric characters.
  • The check digits use ISO/IEC 7064 MOD 97-10. Move the first four characters to the end, replace each letter with a number (A = 10 … Z = 35), read the result as one integer, and a valid IBAN leaves a remainder of 1 when divided by 97.
  • That rearranged integer runs past thirty digits — far beyond the 2^53−1 exact-integer range of a JavaScript number — so this page computes the remainder with arbitrary-precision arithmetic.
  • Each country has exactly one IBAN length. For the countries here: Netherlands 18, Austria 20, Luxembourg 20, Switzerland 21, Germany 22, Ireland 22, United Kingdom 22.
  • The mod-97 step is guaranteed to detect any single character that has been omitted, duplicated or mistyped, and any transposition of two characters.
  • Only the digits 0–9 and the Latin letters A–Z are ever permitted, even in countries that do not write with the Latin alphabet. Whether letters appear in the BBAN is up to each country: the UK and Irish formats open with a four-letter bank identifier, the German BBAN is all digits.
  • An IBAN is traditionally printed in groups of four characters and transmitted electronically without spaces. Burundi, Egypt, Libya and El Salvador are the registered exceptions to the grouping convention.
  • Format validity says nothing about existence: a perfectly formed IBAN can correspond to no account at all, which is exactly what the values on this page are.
