FAQ
What does Signzy's IBAN Verification API check?
Signzy verifies whether an IBAN is valid and active, and retrieves associated bank details such as bank code, bank name, bank ID, address, and SEPA credit, debit, B2B, and card support — all from verified data sources.
How fast does the IBAN verification process work?
IBAN validation happens in real time. As soon as you submit an IBAN, the API returns a validity result and bank metadata within seconds.
Can Signzy verify IBANs across all countries that use IBAN?
Signzy supports IBAN validation across most IBAN-enabled countries, providing accurate bank-level insights regardless of region.
How does IBAN verification help prevent fraud or payment errors?
By detecting invalid or structurally incorrect IBANs before a transaction is initiated, Signzy helps prevent failed transfers, misrouted payouts, and fraudulent account submissions.
Can Signzy's IBAN API be integrated into existing payment or onboarding workflows?
Yes. The API is developer-friendly and designed to integrate seamlessly into existing onboarding, payment, payout, or compliance systems with minimal engineering setup.
What happens if an IBAN is invalid?
The API clearly flags the IBAN as invalid and does not return associated bank metadata, enabling you to block or flag the payment before processing.
Is the IBAN data retrieved from official or verified sources?
Yes. Signzy uses verified, trusted data sources to ensure the bank metadata associated with the IBAN is accurate and up to date.
