The Amazon A-to-Z Guarantee is Amazon’s buyer-protection claim mechanism for orders sold by third-party (3P) sellers. Buyers can file an A-to-Z claim when an item did not arrive within the promised window or when the item received is materially different from what was listed. If Amazon rules for the buyer, the refund is debited from the seller and the claim can count against the seller’s Order Defect Rate (ODR), one of the most closely watched Account Health metrics.
Why It Matters for Sellers
A-to-Z claims sit at the intersection of customer service, fulfillment quality, and listing accuracy. A single claim rarely matters, but a rising claim rate quickly damages ODR — and ODR breaches drive suspensions faster than most other metrics. Just as important, sellers who respond thoughtfully within Amazon’s response window often win claims that would otherwise have gone to the buyer by default. Ignoring the notification is the single most common way sellers lose otherwise winnable claims.
How A-to-Z Claims Work
- Buyer contacts the seller first through Buyer-Seller Messaging; sellers typically have 48 hours to respond.
- If the buyer is unsatisfied, they file an A-to-Z claim from their order history.
- Amazon notifies the seller. The seller has 3 days to respond to any Amazon request for information (per Amazon’s current policy).
- Amazon reviews the messaging history, tracking, and any evidence, then decides.
- If granted to the buyer, the refund is debited from the seller and the claim may count against ODR.
- Sellers can appeal decisions they believe are incorrect through the A-to-Z Claims dashboard.
When Buyers Can File
| Reason | Typical Trigger |
|---|---|
| Item not received | Order past the estimated delivery date with no tracking movement |
| Materially different | Wrong item, wrong size, missing components, or condition mismatch |
| Damaged or defective | Item arrived broken and seller did not resolve |
| Return not refunded | Buyer returned item but no refund was issued |
| Unauthorized charges | Duplicate or unexpected charge on the order |
