Frequently asked questions
Does a valid result mean the account exists?
No. This page checks format, country length, and the mod-97 checksum only. It cannot query bank databases, so confirm details with the recipient before sending money.
Which countries are supported?
Any IBAN from 15 to 34 characters is accepted, with exact lengths enforced for DE, FR, ES, IT, NL, BE, AT, PL, PT, and IE.
Is my IBAN uploaded anywhere?
No. Validation runs entirely in your browser and nothing leaves the page.
