No matching countries.

You can browse cities for free. Generating with a selected city requires paid access; bank targeting starts on Pro, exact BIC targeting starts on Business.

Bank-specific test data

Generate Spain IBANs for a specific bank

Pick a bank: every IBAN carries its real bank code, so your payment form, onboarding or reconciliation test sees the bank it expects.

250 IBANs for one bank Bank name and BIC shown, CSV/JSON export, 14 days. One payment, no subscription. Bank Target Pack · $19 Every bank, every month: compare plans

IBAN Validator

Supports all IBAN formats. Premium plans reveal bank names and BIC metadata when available.

What is checked?

The validator checks country structure, expected length, allowed characters, and the MOD-97 checksum. A passing checksum confirms format only — it does not prove that a real account exists.

Spain random IBAN generator and fake IBAN validator

Use IBANgen as a Spain random IBAN generator for payment-form QA, staging data, API tests and onboarding flows. This page creates fake Spain IBAN numbers with the ES country code and valid MOD-97 check digits, so test data can pass format and checksum validation without using real bank accounts.

A generated Spain IBAN is synthetic data. It can be used as a random IBAN, fake IBAN, test IBAN number, or QA fixture, but it is not connected to a real account and cannot be used for real transactions. The standard Spain IBAN length is 24 characters.

Use the country context to reproduce a local payment-form scenario: start with the format preview, choose a supported bank when you need targeting, and keep the same seed and metadata in a dataset job.

Testing more than one country? The random IBAN generator covers every supported country on one page.

How the Spain IBAN generator works

IBANgen builds a country-aware BBAN, calculates check digits with the international MOD-97 algorithm, and returns a checksum-valid ES test IBAN. The generator is useful when a form, API, parser or validation library requires a realistic Spain IBAN format.

Spain IBAN validation

You can paste one or more generated or external IBANs into the IBAN Validator to check country structure, length and checksum. Paid plans can reveal SWIFT/BIC and bank metadata where registry data is available.

Common uses for fake Spain IBANs

Spain fake IBAN generator FAQ

Can I use this as a fake Spain IBAN generator?

Yes. It generates fake Spain IBAN numbers for development, QA and education. They are checksum-valid test numbers, not real accounts.

Are generated Spain IBANs valid?

They are mathematically valid for IBAN format and checksum checks. Valid format does not mean a real bank account exists.

Can I generate Spain IBANs through an API?

Yes. The IBANgen API supports generation, validation, bulk datasets and test-case workflows.

Do generated Spanish IBANs have valid control digits?

Yes. Both Spanish control digits (dígitos de control) are computed, in addition to the MOD-97 IBAN check digits.

What is the difference between a Spanish CCC and an IBAN?

The CCC is the 20-digit domestic account code; the Spanish IBAN is ES, two check digits and the CCC.

Can I use a generated Spanish IBAN in Stripe test mode?

On 14 October 2026 generated ES IBANs created Stripe SEPA Direct Debit payment methods in test mode and their test payments succeeded. Use them only in test and sandbox environments.

Spanish IBANs: entidad, oficina and dígitos de control

A Spanish IBAN has 24 characters: ES, two IBAN check digits, then the 20-digit CCC: the 4-digit bank code (entidad), the 4-digit branch code (oficina), two control digits (dígitos de control) and the 10-digit account number.

Every generated Spanish IBAN has correct control digits as well as correct IBAN check digits, so forms that validate the CCC accept it. Bank codes are registered Spanish bank codes, so validators and payment providers recognise the bank.
