Frequently Asked Questions
Does validation confirm the account exists?+
No. This tool validates format and checksum only. It does not confirm account ownership or existence.
Which formats are supported?+
IBAN, ACH routing + account, BSB, IFSC, CLABE, and UK sort code + account are supported.
Is my input stored?+
No. Validation runs entirely in your browser and is not sent to a server.
Can I use this for compliance checks?+
As a first pass only. You still need beneficiary verification and KYC checks before sending funds.
What if my format is not recognized?+
Try removing spaces or dashes, or verify the format with your bank. The tool focuses on the most common global formats.
