You can confirm if the IBAN is valid using the following URL:
Note: SEPA Direct Debit cannot cannot be performed with IBAN from countries outside the SEPA zone.
If it is correct, why does it not be accepted?
SlimPay performs a number of controls, there can be various reasons an IBAN is not accepted:
The bank account does not accept direct debit --> provide another Bank Account/IBAN
The IBAN structure is wrong, meaning that it was entered wrongly--> check & enter IBAN
The IBAN used has reached the authorized maximum number of usage within a short timeframe for a same purchase --> if you think this is an error, please contact us
