Walmart Chargeback Code 33: Wrong PO number on invoice
Extracted from source — pending expert reviewLast verified: 2026-07-09
What this deduction means
A Code 33 is assessed when the invoice references the wrong purchase order number — for example Walmart issued PO #5678 but the invoice cites PO #5679 — so Walmart cannot match the invoice to the order.
Typical penalty: The unmatched invoice amount until it is corrected and re-submitted
Common causes
- Manual PO-number entry error on the invoice
- Invoice mapped to the wrong PO
- PO number transposed or mistyped
How to prevent Walmart code 33
- Pull the PO number directly from the 850 into the 810 (no manual entry)
- Validate the PO number exists before transmitting
- Automate PO-to-invoice matching
