Not a shipping label
An RA authorises the receipt; it is not paid postage. Some sellers pair the RA with a prepaid label at their cost, others expect you to buy your own label. Which one applies is spelled out in the RA email.

What an RA number is, and why a return needs one
An RA number — short for Return Authorization; also called RMA or RGA — is the code a seller issues before a return ships. It ties the parcel arriving at a warehouse dock to the original order, the refund line and the correct returns bin. Ship a box back without one, and it sits in an anomaly queue for weeks or is refused at the door and returned at your cost. This page covers how to get one, where to put it on the box, and what the number does not cover.

Warehouses match returns to orders by that number. No number, no match, no refund on time.
Get the RA before you print the label
- Find the seller's return path. On a marketplace (Amazon, eBay, Walmart, Etsy, Shopify), start a return from the order page — the RA is generated automatically and sits on the return summary screen. On a direct-brand website, look for a Returns or Contact link and open a request; the seller emails an RA within a business day.
- Describe the reason accurately. Damaged in transit, wrong item, doesn't fit, changed my mind — the reason decides whether shipping is on the seller or the buyer, and whether the item goes to a refurbish line, resale bin or scrap.
- Receive the RA and, sometimes, a prepaid label. The email or download will include the RA number (an example: RMA-2026-08-11-4472) and often a PDF label. Read the RA email in full; it tells you which of your items are covered and any deadline.
- Write or print the RA on the outside of the box. Next to the shipping label, not on it, in at least 1-inch letters. Most warehouses ask for the format the RA email specifies — RA# or RMA- followed by the digits.
- Ship within the window. RA numbers expire, typically in 14 to 30 days. Send within the window; a late arrival can be refused or reduced by a restocking fee.
Where the number goes on the box
A warehouse receiving team reads the address side of the parcel first. The RA number belongs on the same face as the shipping label, offset so it does not overlap the barcode. A permanent marker, a printed slip taped down, or a printed sticker all work; a pencil scribble does not.
[SHIPPING LABEL — SELLER'S RETURN ADDRESS]
RA# 12345
Order 1006-7890
RA# 12345
Order 1006-7890
Some sellers also ask for the RA to appear on a printed slip inside the box, so the item can be routed once the outer carton is opened. Include both if the return email says so; the outside label is the receiving dock's shortcut, the inside slip is the finishing team's.
What the RA does not cover
Not a refund confirmation
The RA opens the case. The refund lands after the warehouse receives, inspects and dispositions the item. That can take days to weeks after the parcel scans in. Tracking + inspection is the true timeline, not the label print.
Not a shield against restocking fees
A seller can honor the RA and still deduct a restocking fee under its own return policy. Look for the percentage on the return policy page before you ship; opened electronics and heavy items are the categories most often docked.
Common trouble, and how to head it off
A missing RA on the outer box is the top reason a return sits for weeks. The second is a mismatch between the item in the box and the item on the RA — the wrong color, the wrong quantity, the wrong SKU. If you cannot ship the item on the RA, cancel the RA and open a new one for the correct item rather than shipping under an authorization that names something else.
A third failure mode is an expired RA. Warehouses will accept an expired RA in some cases at the discretion of the receiving team, but the safer move is a call or email to the seller to renew it before shipment. On marketplace returns, closing an expired RMA and opening a fresh one is usually a two-click flow.
Cost of the return parcel
If the seller provides a prepaid label, print and go. If the return is on you, quote the packed parcel on the calculator so you can pick the cheapest carrier for the box you actually have. USPS Ground Advantage is often the cheapest on small returns; UPS or FedEx Ground can beat it on longer or heavier boxes. Same box, one form, four rates in a row.
Common questions
What does RA stand for?
Return Authorization. Some sellers use RMA (Return Merchandise Authorization) instead, or RGA (Return Goods Authorization). The three terms describe the same thing: a code the seller issues before a return ships, which routes the returned item to the correct queue at the receiving warehouse.
Why do warehouses reject returns without an RA number?
Because a receiving dock accepts hundreds of parcels a day and has no way to tie an unmarked box to the original order without one. Boxes without an RA sit in a returns-anomaly queue for weeks or are returned to sender at the customer's cost.
Where do I put the RA number on the return package?
In bold marker or a printed label on the outside of the box, next to (not on) the shipping label. Most sellers ask for it in the format RA# 12345 or RMA-12345 written in at least 1-inch letters. Some also ask for it inside the box on a printed slip.
Does an RA number cover the shipping cost?
No. The RA is authorization, not a label. Many sellers pair the RA with a prepaid return label; others require the customer to buy their own return postage. Read the return-policy page or the email that issued the RA to know which.
How long is an RA number valid?
Usually 14 to 30 days from issue. After the window the RA expires and the return has to be re-authorised, sometimes with a restocking fee attached. Ship as soon as the label is in hand rather than saving the parcel for later.
