What is an IBAN name check?
A structural IBAN check tells you whether an account number can exist. The name check goes further: it confirms whether the name you were given matches the account. That is the difference between catching a typo and catching fraud with somebody else's account number.
If you pay out to consumers, think refunds, winnings, marketplace sellers or insurance claims, the name check belongs before the payment leaves, not in the complaint queue after it.
How the name check works in a flow
The IBAN name check is a building block you place at the exact moment a consumer enters their account number.
1. Consumer enters IBAN and name
In your own form or in the hosted onboarding wizard, styled to your brand.
2. The check runs instantly
The account holder name is compared with the name given. Match, close match or no match comes back live.
3. You decide what happens
Pass, ask for a correction, or reject. Results also reach your systems over the REST API and webhooks.
IBAN verification coverage across Europe
The free structural check works for every IBAN country. The name check covers Dutch account numbers in full and European IBANs where banks return account holder data. Adults holding an IBAN per market:

GDPR and compliance
Built for lawful consumer checks
Consumer checks touch personal data, so privacy is part of the design. The consumer walks through the check themselves and sees what is being asked. Each step retrieves only what that check needs, from official sources, and every result is recorded.
Official sources and registers, no scraped profiles
Data minimisation: each check reads only the fields it needs
Every result recorded, ready for regulators and audits

Frequently asked questions
Question not listed? Request a demo
Is the IBAN verifier on this page free?
Yes. The structure and check-digit validation runs entirely in your browser, unlimited and free. Nothing is sent or stored.
What is the difference between verifying an IBAN and an IBAN name check?
Verifying the IBAN confirms the number itself is well-formed. The name check also confirms the given name belongs to that account. For payouts you want both.
Can I embed the name check in my own product?
Yes. It is a building block in an onboarding flow you start through a wizard URL or the REST API, with per-step results over the API and webhooks.
How do I get access to the name check?
On quote: request a demo, tell us your volume and you receive a tailored quote. After approval you get your production key. Self-service signup comes later.
