Automated return of unpaid direct debits (ARUDD)
A UK Bacs reporting service that automatically informs organisations when a Direct Debit collection has failed and the funds have not been paid by the customer’s bank. ARUDD messages provide standardised reason codes explaining why the payment was returned unpaid, for example insufficient funds, account closed, instruction cancelled, or payment stopped. These automated notifications enable organisations to quickly update their records, trigger retry or customer contact processes, manage cash flow expectations, and maintain accurate reconciliation, while reducing manual investigation and supporting compliance with Direct Debit scheme requirements.
