IBAN Validator

Terms of Use

1. Acceptance

By using this website ("IBAN & Card Validator") you agree to these Terms of Use. If you do not agree, please stop using the site.

2. Service description

This site provides free, client-side tools to validate IBAN bank account numbers and payment card numbers. All validation runs entirely in your browser — no data is transmitted to any server.

3. No data collection

We do not collect, store, or process any IBAN or card numbers you enter. The only information saved is your language preference (cookie) and light/dark theme (localStorage), stored locally in your own browser.

4. Advertising

This site displays advertisements served by Google Ads (Google LLC). Google may use cookies to serve ads based on your prior visits to this or other websites. You can opt out at google.com/settings/ads.

5. Accuracy

Validation results confirm structural correctness only (format, length, checksum). They do not confirm that an account exists, is active, or belongs to any specific person. Always verify with your bank before sending funds.

6. Limitation of liability

This service is provided "as is" without any warranty. We are not liable for any financial loss resulting from reliance on validation results.

7. Changes

We may update these terms at any time. Continued use of the site constitutes acceptance of the updated terms.

8. Contact

For questions, see our Contact page.
