IBAN Validation Tool

The IBAN Validation Tool checks International Bank Account Numbers for syntactic correctness and math-based integrity. It validates country codes, lengths, and the MOD 97-10 checksum per ISO 13616. The tool runs in a client-side environment to preserve privacy and speed, and is suited for finance teams, developers, and data quality engineers who process IBANs in payments and onboarding.
Conceptually, it normalizes input, derives country-specific expectations, applies checksum logic, and returns a structured result: validity, country, length, and error details. It does not confirm account activity or banking status; it only confirms that an IBAN adheres to standard formatting and mathematical rules.
Unique value lies in immediate, deterministic feedback that can be integrated into data pipelines and payment workflows. It supports batch or single-IBAN validation, accepts spaces in input, and yields machine-readable outputs suitable for downstream validation, enrichment, and auditing.
Core features include syntax validation, checksum verification, country-length checks, error codes, and deterministic outputs. Common use cases include supplier onboarding, payment initiation, ledger reconciliation, and data cleansing. The tool emphasizes privacy, offline operation, and straightforward integration.
