Amazon’s December 18 Return Label Change: What FBM Sellers Need to Know

Prepaid return labels are not new to seller-fulfilled orders.

Amazon’s existing documentation says US sellers are automatically enrolled in its prepaid returns program, which provides labels through Buy Shipping. It also describes exemptions and the process for manually supplying prepaid labels through Manage Seller-Fulfilled Returns.

This announcement is therefore not the introduction of prepaid returns across FBM, and sellers should not count every existing return label as a new expense.

The change removes the address-only approach for affected returns. Instead of providing a return address and leaving the customer to arrange shipping, sellers must provide a prepaid label or issue a full refund without requiring the item back within the stated timeframe.

The first place to look is the part of your operation that still relies on address-only labels, manually supplied labels, or return instructions sent through messages. Those are the procedures most likely to need attention.

Amazon’s notification gives sellers two ways to meet the requirement within seven calendar days of a return request:

1. Upload a prepaid return shipping label against the request through Manage Seller-Fulfilled Returns.
2. Issue a full refund without requiring the customer to return the item.

The upload location matters. Amazon specifically says labels shared through Buyer-Seller Messaging or other channels outside the Manage Returns workflow do not meet the requirement.

If your current procedure is to purchase a label and message it to the customer, that procedure needs to change. Providing the label is only part of the task; it must also go through the required workflow.

The seven-day window is not a replacement for other return-response requirements. Amazon’s existing documentation includes a separate 24-hour response requirement for requests needing manual authorization. Do not turn the new label deadline into a blanket seven-day response policy.

If neither a prepaid label nor a returnless refund is provided within the timeframe, Amazon says it may automatically issue a returnless refund and deduct the amount from your selling account.

An unattended request can therefore become a refund without recovery of the merchandise.

There is a difference between choosing a returnless refund because the economics make sense and having one issued because nobody completed the required action. Your returns process should preserve that choice.

Not necessarily. Prepaid describes how the shipping is arranged, not automatically who ultimately bears the cost.

Amazon’s guidance distinguishes shipping-cost responsibility by return reason, including whether the return is seller-fault. Providing a prepaid label and being responsible for the final shipping charge are separate questions.

The December notification changes the label requirement. It does not, by itself, announce that every return now qualifies for seller-paid shipping.

When reviewing the financial impact, separate labels you already provide from newly affected returns. Then apply Amazon’s current rules for the relevant return reason rather than assuming every label charge is either yours to absorb or yours to deduct.

My objection is not that prepaid labels are unfamiliar. It is that Amazon is changing an important returns workflow during Q4.

Even with advance notice, sellers need to identify affected products, revise procedures, train staff or outside help, and confirm that labels are uploaded correctly.

December 18 is a bad time to discover that an established procedure no longer meets Amazon’s requirements.

The shipping-cost timing adds to the frustration. USPS’s announced 2026 holiday pricing window runs from October 4 through January 17, 2027, covering services including Ground Advantage and Priority Mail. The December 18 change falls inside that peak-season pricing period.

That does not mean every carrier, service, or negotiated rate reaches its annual high at the same time. It does mean sellers using affected USPS services are implementing this change during a period of elevated holiday shipping prices.

Our USPS holiday price increase breakdown explains the affected services, weight bands, and zones.

In my view, major operational changes belong outside the holiday rush whenever possible. Requiring a returns-process update while sellers are managing peak-season operations and higher shipping costs is poor timing.

Review recent return requests and flag where your team uses address-only labels, supplies labels manually, or sends them through Buyer-Seller Messaging.

Separate those requests from returns that already receive prepaid labels automatically. That gives you a more useful estimate of the additional work and potential cost than applying a label charge to your entire return volume.

“Send the customer a label” is not a sufficiently precise instruction for affected returns.

Your written procedure should identify who uploads the label, where they upload it, and how they confirm the action is complete. Include who may approve a returnless refund and which requests require escalation.

I would review unresolved requests daily rather than manage them against the seven-day limit.

Give the queue an owner and a backup for days off or unexpected absences. Escalate problems early enough to resolve a missing label, technical issue, or refund decision before the deadline.

For low-value products, recovering the item may cost more than the merchandise is worth.

Compare return shipping and handling costs with the value you realistically expect to recover. Establish approval limits so your team does not need a new decision from you on every low-value return.

If recurring Seller Central work is stretching your team, our Amazon virtual assistant services guide covers hiring options and tasks you can delegate.

A trained VA can help monitor requests, flag approaching deadlines, and carry out approved procedures. Give that person clear instructions about permitted actions, refund approval limits, and when to escalate a problem.

Hiring help only works if the process they are following is correct.

Amazon’s notification temporarily excludes heavy and bulky items from the new requirement. It does not provide an end date for that exclusion.

Treat it as an exception to monitor, not a permanent foundation for your returns process.

The notification also does not define the precise eligibility criteria. Do not assume an item qualifies simply because you consider it large or expensive to ship; confirm how Amazon classifies the affected products.

Before December 18, check the notification in your seller account and its linked help documentation against your actual returns procedure. Pay particular attention to manually handled requests and any products you believe qualify for an exception.

The goal is straightforward: every affected request gets the required action, through the correct workflow, before the deadline.

For most US seller-fulfilled returns, not after December 18, 2026. Labels that require the customer to arrange and pay for return shipping will no longer meet the requirement. Heavy and bulky items are temporarily excluded, and Amazon’s notification does not give an end date for that exclusion.

No. Amazon specifically says labels shared through Buyer-Seller Messaging or other channels outside the Manage Returns workflow do not meet the requirement. Upload the prepaid label against the return request in Manage Seller-Fulfilled Returns.
