Walmart Chargeback Code 21: Store-level shortage
What this deduction means
Some shortages only surface once the shipment reaches the store, not at the distribution center's first receipt. Walmart books those missing units as a Code 21 and deducts their cost.
Typical penalty: Equal to the cost of the units short at the store
Common causes
- Units lost between the DC and the store during handling
- A miscount that only surfaced at store receiving
- A direct-store-delivery (DSD) discrepancy
How to prevent Walmart code 21
- Ensure carton and unit counts are accurate and labeled before shipment
- Keep signed delivery proof to dispute store-level shortages in the APDP
- Reconcile DSD deliveries against store receipts

Walmart shortage codes (21-25): which one is it?
Codes 21 through 25 all fire when Walmart records fewer units than your invoice billed. They share one root, a gap between what shipped, what was billed, and what was received, but each one pins that gap to a different point in the flow. Match the symptom to the code before you dispute or change a process.
| Code | How to tell it apart |
|---|---|
| 21 (this page) | Shortage surfaces at the store, after the DC already received the freight (includes DSD). |
| 22 | Invoice bills more units than the DC or store logged as received. |
| 23 | Shipper Load and Count: you loaded and counted the trailer, so the count is your responsibility. |
| 24 | Signed short on the carrier's freight bill at the DC dock. |
| 25 | No receipt matched the invoice at all, often because the 810 arrived before delivery. |
