IBAN Validator Bulk Tool
Paste multiple IBANs (one per line) and get a table with MOD-97 validation result, country code, and length.
Come utilizzare Validatore IBAN Bulk
Attach the Iban list one per row
Copy and paste Iban numbers into the text area for each row. The tool accepts iban with or without spaces between character groups.
Click "Validate" to start bulk monitoring
Each line is normalized (spaces removed, uppercase) and validated for expected length by country and MOD-97 checksum (ISO 7064).
Read the table with outcome, country and error
Table shows normalized IBAN, 2-letter country code, state (valid/invalid), and specific error code when validation fails (length error, unknown country, invalid checksum).
Export results to CSV
Use the "Export CSV" button to download the entire results table (IBAN, outcome, country, error) and integrate it into your reconciliation or onboarding client processes.
Suggerimenti
- If you need to enter an IBAN from a CSV file, simply paste the column directly. Each cell on a separate line will be interpreted correctly.
- Use export CSV to track invalid IBANs for manual correction before large-scale import into a payment system.
Domande frequenti
How does MOD-97 control work?
Checksum MOD-97, defined by the ISO 7064 standard, reorganizes the IBAN by moving the first four characters to the end, converting letters to numbers (A=10, B=11, etc.) and verifying that the remainder of division by 97 is exactly 1. If the remainder is different, the IBAN contains a digit entry error.
What does the UNKNOWN COUNTRY error mean?
Means the first two characters of the IBAN do not match any of the country codes present in the standard IBAN length table supported by the tool (over 70 countries). Verify that you have correctly copied the country code at the beginning of the string.
What does the LENGTH EXPECTED_N_GOT_M error mean?
Indicate that for the reported country, the expected IBAN length is N characters, but the provided one is M. This is a typical symptom of an incomplete or pasted IBAN with missing or duplicated characters.
How many Iban can you validate at once?
There is no limit imposed by the tool: line-by-line processing occurs entirely in the browser, so practical capacity depends only on the device's resources for large lists (thousands of lines).
Does the IBAN correspond to an existing account?
No. Formal control only checks for correct length and checksum (country-specific, MOD-97), not actual account existence at the bank - that requires a dedicated banking verification service.
