Code 23: Carton Shortage SLC
Learn what Walmart Code 23 deductions mean, why Shipper Load and Count (SLC) shortages occur, how to prevent them, and the documentation needed to dispute invalid claims.

Overview
Code 23 deductions occur when a shipment arrives short and the freight bill is marked Shipper Load and Count (SLC). Under an SLC shipment, the supplier is responsible for loading the trailer and verifying carton quantities, while the carrier does not confirm the case count.
Code 23 deductions are uncommon and are often replaced by the more general Code 22 or Code 24 shortage deductions.
How to Prevent Valid Code 23 Deductions
- Ensure every case listed on the freight bill is shipped according to the purchase order.
- Verify that all ordered cases are loaded before the shipment leaves your facility.
- If the shipment is not Shipper Load and Count, ensure the Bill of Lading is not marked SLC.
- Have the driver record the correct case count on the Bill of Lading and avoid using the SLC designation unless appropriate.
Can It Be Disputed?
In most situations, Code 23 deductions should be disputed with the carrier rather than Walmart. If you need proof that Walmart received the shipment short, you can submit a dispute through the Accounts Payable Disputes Portal (APDP) in Retail Link to request the supporting Proof of Delivery.
Supporting Documentation
- If the Proof of Delivery is signed short, pursue a carrier claim using the signed Proof of Delivery.
- If the Proof of Delivery is signed in full but Walmart incorrectly recorded the shipment, provide the signed Proof of Delivery showing the shipment was received in full. The purchase order number should be clearly listed.
- Bill of Lading showing the driver recorded the correct case count and that the Bill of Lading is not marked Shipper Load and Count (SLC).
Conclusion
Code 23 deductions involve shortages on Shipper Load and Count shipments and are relatively uncommon. Proper shipping verification, accurate Bills of Lading, and clear case counts can help prevent these deductions. When shortages occur, determine whether responsibility lies with Walmart or the carrier and use the appropriate supporting documentation when filing a dispute or carrier claim.
