IBAN Validator
Validate your IBAN quickly and accurately with our advanced IBAN Validator tool.
Use uppercase letters, omit spaces, and include all country digits.
Enter an IBAN to begin validation.
How to use
Paste or type the full IBAN into the input field, then click Validate (or wait for the live check). The validator strips whitespace and uppercases the input automatically.
Valid input requires two-letter country code, two check digits, and up to 30 alphanumeric characters following the official ISO 13616 formatting rules.
Methodology
We evaluate the IBAN structure against the ISO 13616 definition (two letters, two digits, rest alphanumeric). Any deviation immediately flags the IBAN as invalid, matching the lightweight legacy behavior.
- Empty submissions trigger a reminder to enter the IBAN.
- Only the official pattern is enforced so results mirror the legacy validator.
