Bulk IBAN Validator
Batch processingValidate a list of IBANs in one go. Paste one per line (or comma/semicolon separated) and get a clear valid/invalid breakdown with error details for each. Useful for validating payee lists before building a pain.001 batch.
Paste your IBANs and click "Validate all"
Input format
One IBAN per line. Commas and semicolons are also accepted as separators. Lines starting with # are treated as comments and ignored. Spaces within IBANs are stripped automatically.
Common issues
- •Excel/CSV exports — spreadsheet tools sometimes add extra whitespace or BOM characters at the start of a file. Use the JSON export to get clean, normalized output.
- •Mixed separators — if pasting from a CSV, the validator handles commas and semicolons automatically alongside line breaks.
- •Partial IBANs — validation is country-aware. A German IBAN must be exactly 22 characters — truncated inputs will always fail.
