IBAN and BIC validator for banking forms and test data

What is IBAN & BIC Validator?

An IBAN identifies a bank account internationally, while a BIC identifies a bank or financial institution.

Main use case: Validate IBAN and BIC values while testing SEPA forms, payment screens, QA fixtures or banking data entry.

Common use cases

Banking forms

Check whether a field accepts a plausible IBAN or BIC format.

QA test data

Validate generated values before adding them to fixtures.

SEPA mockups

Prepare realistic payment form examples.

How to use the tool

1. Paste an IBAN or BIC.
2. Run the local validation.
3. Review country, length and checksum feedback.
4. Use only fictitious or sandbox values for tests.

Best practices

• Use realistic test values when validating forms, exports or API payloads.
• Keep real customer, banking and production secrets out of public tools.
• Check the output format before copying it into a production workflow.
• Document whether a value is generated, validated, converted or only estimated.

Common mistakes

Confusing valid format with real-world validity

A generated or locally validated value can match a format without proving that it exists in an official system.

Using real production data

Public utilities are best for test data, demos, fixtures, QA and quick checks, not for confidential values.
