# Blocked IBANs

## Preliminary Remarks

To counteract potential **misuse of payment methods** , **IBANs** can be excluded from payment attempts via a blacklist . The IBAN blacklist can be maintained in the Frisbii Media Merchant Backend itself. The accounts for blocked IBANs are rejected in the checkout and cannot be saved in either the Self Service or the Merchant Backend.

> [!TIP]
> **Note**: It is important to note that the blocking of an IBAN only affects the specific account linked to that IBAN and **not** all of a person's accounts with the bank or other means of payment deposited by that person.
