ISO 20022 reason code

AC07: Closed creditor account number

The creditor account is closed. AC07 is an ISO 20022 reason code used as a status reason and a return reason: you will see it in pain.002, pacs.004 and camt.053.

What AC07 means

The creditor’s (payee’s) account is closed.

Not to be confused with: AC07 names the creditor’s side; AC04 is a closed account on either side and AC05 the debtor’s.

A reason code always comes with a status or an action: on its own it says why, not what happened. In a status report look at the status next to it (RJCT means the payment will not be executed); on a statement the returned entry tells you the money has come back.

Where AC07 appears

AC07 belongs to two of the ISO 20022 reason code lists, so it can arrive in these places:

  • Status reason (ExternalStatusReason1Code): in a payment status report (pain.002 from a bank to its customer, pacs.002 between banks) that rejects or holds a payment.
  • Return reason (ExternalReturnReason1Code): in a payment return (pacs.004) after the money has moved, and the returned entry on the account statement (camt.053) or notification (camt.054).

In a status report, AC07 explains a status such as RJCT, at transaction level here (the same StsRsnInf block can sit under the group or a payment block):

What to do about AC07

  • If you sent the payment or the collection: Get the payee’s new bank details through a channel you trust, update your records and pay again.

A request to change a supplier’s bank account is a common fraud pattern: confirm new details before you pay to them.

Your bank’s implementation guide and the scheme’s rulebook (for SEPA, the EPC rulebooks) say exactly when it may use AC07; banks do not all apply a code the same way.
