About this tool

Made for the task at hand.

Inspect an International Bank Account Number without transmitting banking details. The validator checks its country and expected length, rearranges it for the ISO 13616 mod-97 calculation, and identifies Swiss QR-IBANs by IID range.

How to use

  1. Paste an IBAN with or without spaces.
  2. Review country, expected length, and normalized characters.
  3. Check the mod-97 result, QR-IBAN status, and friendly grouping.

Common questions
Does checksum validation verify the bank account?

No. It detects many transcription errors but cannot confirm that the account exists or belongs to a particular person.

What is a QR-IBAN?

A QR-IBAN is a Swiss or Liechtenstein IBAN whose institution identification falls in the 30000–31999 range, used for QR-bill procedures.
