Thanks, that helped me find another reason why PayPal and Stripe can't send money to a TransferWise account: the sender account must include the account name and it must match [https://transferwise.com/help/article/2200390/creating-a-tra...].

The account name will be required in future UK banking regulations, at last, so this issue may get resolved by Stripe, PayPal, etc., just not soon.

Looks like TransferWise are interested in fixing the debitable account issue.
