Synthetic IBAN & BIC/SWIFT test data generator

Generate syntactically valid IBAN test data with correct MOD-97 check digits and choose either stored BIC samples, fake BIC-shaped codes, or a custom sandbox BIC. No bank, payment, or financial-service connection is made.

Synthetic test data only

This tool generates synthetic IBAN-like test data for software testing and education. It does not create real bank accounts, does not verify account ownership, and must not be used for fraud, payments, or impersonation.

Generated IBANs are syntactically valid test data, not real bank accounts, and not usable for payments. Stored BIC samples identify institutions by code only and do not verify any account or payment usability.

BIC registry status can change and may be branch-specific. Verify samples with your provider before any real integration.

Validate an IBAN

Paste a supported IBAN to check format, length, and MOD-97.

Generated batch

Stored BIC samples come from the local reference list. Fake and custom modes remain available for sandbox workflows that do not require a stored bank code.

What is an IBAN?

An IBAN is an international account number format made from a country code, two check digits, and a country specific BBAN. This app creates synthetic examples for validation workflows and UI testing.

What is MOD-97?

MOD-97 is the checksum rule used by IBANs. The country code and check digits move to the end, letters become numbers, and a valid IBAN leaves a remainder of 1 when divided by 97.

Format valid vs. real bank

A valid format only means the string follows supported length, character, BBAN, checksum, or BIC shape rules. It does not prove that a bank account or registered bank identifier exists.
