Please don’t generate IBANs and use them to send us SWIFT/SEPA payments 
We don’t support international payments and although the originating bank should detect this they sometimes don’t.
I’ve already had a couple of these this week and it takes a lot of engineering time to locate these failed transactions our end and send them back/credit them. It is obviously also stressful for the customer as they have often paid fees to make the payment and they money just seems to have vanished.
Tl;dr: please use Transferwise
