An Amazon A-to-z Guarantee claim is filed when a buyer says an order didn’t arrive or isn’t what they expected, and the seller didn’t resolve it. For sellers, these claims matter a lot: they count toward your Order Defect Rate and can hurt your account health. I handle buyer messages and claims for Amazon sellers, and this guide explains how A-to-z claims work, how to respond quickly and correctly, how to appeal, and how to prevent them in the first place.
Key Takeaways
- Buyers can file an A-to-z claim when an item didn’t arrive, is materially different, or a promised refund wasn’t issued.
- Respond quickly. Amazon gives sellers a limited time to respond, and no response can decide the claim against you.
- Claims granted against you count toward your Order Defect Rate (target under 1%).
- For FBA orders, Amazon handles fulfillment issues; most A-to-z exposure is on FBM orders.
- Valid tracking, clear listings and fast replies prevent most claims.

What Is an Amazon A-to-z Claim?
The A-to-z Guarantee protects buyers who purchase from third-party sellers. If a buyer has a problem with timely delivery or the condition of an item and the seller doesn’t fix it, the buyer can ask Amazon to step in. Amazon reviews the case and can refund the buyer, often at the seller’s expense.
Common Reasons for A-to-z Claims
| Reason | Typical cause |
|---|---|
| Item not received | Late or lost shipment, no valid tracking |
| Item materially different | Wrong item, damaged, missing parts, not as described |
| Refund not issued | Buyer returned the item but wasn’t refunded |
| Return not accepted | Seller didn’t follow Amazon’s return policy |
How to Respond to an A-to-z Claim
- Go to Performance → A-to-z Guarantee Claims and open the claim.
- Respond as fast as possible, well within the time Amazon shows.
- Either refund the buyer if the claim is fair, or provide evidence: valid tracking with delivery confirmation, photos, messages and your listing details.
- Keep your reply short, factual and polite.
- Message the buyer through Buyer-Seller Messaging to try to resolve it directly.
Tip: If the buyer’s complaint is fair, refunding quickly is often better than fighting a claim you will lose. Claims granted against you hurt your metrics more than a refund does.
How to Appeal an A-to-z Decision
If Amazon decides against you and you have strong evidence (for example signed delivery confirmation), you can submit an appeal from the claim page. Include only clear facts and documents, and check the appeal window shown in Seller Central.
How A-to-z Claims Affect Your Account
Claims count toward your Order Defect Rate (ODR), along with negative feedback and chargebacks. Amazon expects ODR under 1%. A rising ODR can lead to warnings and restrictions. Track it on your Account Health dashboard.
How to Prevent A-to-z Claims
- Ship on time and always upload valid tracking.
- Describe items accurately and keep listings up to date.
- Answer buyer messages within 24 hours and offer solutions early.
- Process returns and refunds promptly.
- Consider FBA for fast, Amazon-handled fulfillment. See FBA vs FBM.
