How to Upload Prepaid Return Labels in Seller Central
Covers Amazon's requirements and process for uploading prepaid return labels in Seller Central, including file specs, the step-by-step workflow, best practices, and international return deadlines.
Overview
Amazon requires sellers to provide prepaid return labels to customers in certain return scenarios to remain compliant with the marketplace's return policy. Understanding how to properly upload these labels through Seller Central is essential for avoiding A-to-z Guarantee claims, maintaining strong seller feedback ratings, and ensuring a smooth return experience for buyers.
Key Points / What Sellers Need to Know
- 48-hour upload window — Sellers must upload valid prepaid return labels within 48 hours of a return being created. Missing this deadline can result in Amazon stepping in on the seller's behalf.
- Use the Manage Returns page only — Return labels must be shared exclusively through the Manage Returns page in Seller Central. Do not send labels through buyer-seller messaging, as this does not meet Amazon's compliance requirements.
- Buyer-seller messaging exception — While return labels cannot be sent via messaging, sellers may still use buyer-seller messaging to share customs-related documentation with international buyers when needed.
- Real-time label validation — When you upload a shipping label image, Amazon's system validates it in real time, typically within seconds. Invalid labels will trigger an error message immediately.
- International return deadlines — For international returns with a non-US domestic return address, prepaid labels must also be uploaded within two days of return creation. Failure to do so may result in Amazon proactively issuing a refund to the buyer.
Label Requirements
Before uploading a prepaid return label, sellers need to ensure the file meets Amazon's technical and content specifications. The label image must be no larger than 2MB and saved in one of the supported file formats: JPG, PNG, BMP, GIF, or TIF. The label itself must clearly display the return address and include the carrier tracking ID number. Uploading a label that is missing either of these elements will cause the validation to fail. Always use a clear, unused shipping label in portrait orientation to avoid rejection during the upload process.
