US seller-fulfilled returns require prepaid labels within 7 days

41 days left — Dec 18, 2026

What stops working
From December 18, 2026, an address-only return label no longer satisfies Amazon for most US seller-fulfilled returns. Sellers must upload a prepaid label through Manage Seller-Fulfilled Returns within 7 calendar days or Amazon refunds automatically and debits the seller.
Who is affected
US merchants fulfilling their own Amazon orders (FBM).
Official migration path
Upload prepaid labels via the Manage Returns workflow, or enable automatic returnless refunds where appropriate.
What the official path does not cover
Labels sent through Buyer-Seller Messaging do not count. Carrier-label automation must be wired into the Manage Returns workflow.
