Overview

Validate IBAN bank account numbers in bulk — with the official mod-97 checksum and country length rules — and get back the country, bank code and a pretty-printed format. Sanity-check bank details before initiating transfers or importing them.

What it does

Checks each IBAN's country code, length and mod-97 checksum.
Extracts country, check digits and bank code (best-effort per country).
Returns the grouped, pretty-printed IBAN.

Use cases

Payments & payroll — verify bank details before transfers.
Onboarding — validate IBANs entered by customers/suppliers.
Data quality — flag invalid account numbers in bulk.
