What does 'Do Not honour' mean?
‘Do not honour’ is an error response sent by a customer’s bank when they decline a transaction for reasons best known to them, or when a restriction has been placed on a customer’s account.
This error is very common with international transactions where a customer's bank blocks their transactions attempts from being successfully processed until they can verify that their customer is the one initiating the transaction.
What can I do about it?
As a merchant, please advise your customer to reach out to their bank to confirm why their transaction attempt was blocked and also to help resolve this.
As a customer, we also suggest reaching out to your bank for further assistance.
