FAQ
Frequently asked questions
What is the difference between IBAN and BIC?
IBAN identifies a bank account, while BIC identifies the bank or financial institution.
Can a valid IBAN receive money?
A format-valid IBAN is not proof that the account exists or can receive payments.
How is an IBAN checksum checked?
IBAN validation commonly uses a modulo 97 checksum after rearranging and converting characters.
Does this tool generate fake IBAN values?
No. This page validates IBAN and BIC values. To create fake IBAN and BIC data, use the IBAN & BIC generator.
Can I use this with Stripe or a PSP?
Use official sandbox values from your payment provider for real integration tests.
Are my inputs sent to a server?
