This ACH return code applies specifically to RCK (Represented Check Entry) transactions when attempting to electronically re-present a bounced check. R52 occurs when the customer has proactively requested their bank to place a stop payment order on the original check that is now being electronically re-presented. This indicates the customer has intentionally blocked the check from being processed.
Error message: "The RDFI determines that a stop payment order has been placed on the item to which the RCK entry relates."
What Causes ACH Return Code R52?
The R52 ACH return code means "Stop Payment on Item Related to RCK Entry" and indicates that a customer has placed a stop payment order on the original paper check that is being electronically re-presented through a Represented Check Entry (RCK). When a customer places a stop payment order with their bank, they are requesting that the financial institution prevent a specific check from being processed, regardless of whether it's presented physically or electronically.
This return occurs when a merchant attempts to use RCK to electronically re-present a bounced check, but the customer has already instructed their bank to stop payment on that specific check. Customers may request stop payments for various reasons including fraud concerns, disputes about goods or services, insufficient funds to cover the payment, or simply changing their mind about the transaction. Unlike other RCK return codes that relate to eligibility or technical issues, R52 represents a deliberate customer action to block the payment.
Can You Retry R52 Payments?
You cannot retry R52 payments using the same RCK method because the customer has specifically instructed their bank to prevent this check from being processed. The stop payment order remains in effect and will block any future attempts to process the same check electronically. You must contact the customer to understand why they placed the stop payment and arrange alternative payment methods if they still wish to complete the transaction.
How to Respond to an R52 Code
An R52 return requires direct communication with the customer since they have intentionally blocked the check payment and may need to resolve underlying issues before proceeding.
When Your Customer's Payment Fails
- Contact Customer Immediately
Reach out to understand why they placed a stop payment on the check and whether they still intend to complete the purchase. - Investigate the Reason
Determine if the stop payment was due to a dispute, fraud concern, insufficient funds, or change of mind about the transaction. - Resolve Any Disputes
If the stop payment was due to issues with goods or services, address those concerns before requesting new payment. - Arrange Alternative Payment
