The banks use this response code as they see fit. If you receive this response code for a customer, and you have never had a successful debit for that customer, first check the BSB and account number. This could indicate one of the following:
- Account does not allow Direct Debit
- Incorrect Account Number
- Insufficient Funds
- Suspected Fraud
- Any other rule imposed by the account holder's bank that causes a decline (e.g. daily limit exceeded, duplicate transaction suspected, etc)
