What the invoice actually has to be, which rules genuinely conflict, and the supplier type that fails no matter how perfect the document is. Read from Amazon staff forum posts and Amazon's publicly hosted Code of Conduct, checked September 2 2026.
Read this first. This is a map, not a rulebook. Seller Central's help pages sit behind a login, so nobody, this page included, can quote the live requirement to you. Requirements are also account specific and change without announcement. The authoritative answer is your own Apply to Sell screen. Use this to know what to look for there.
Naming which one you are in is most of the game, because the numbers are different and people quote them at each other interchangeably.
| Apply to Sell, before you list | Policy violation appeal, after a complaint | |
|---|---|---|
| Recency | Invoice within about 180 days | Within about 365 days |
| Quantity | At least 10 units | Enough to cover your sales volume for the cited item |
| How many invoices | At least one | Whatever covers the volume |
| Buyer details | Name and address matching the selling account, exactly | |
Honesty note on that table. The split above is a synthesis from consistent evidence across staff posts and the application text, not a rule Amazon states in one place. A separate read of the same forum thread called the 10 unit and 180 day figures largely folklore. The sources genuinely conflict, so treat the table as the shape of the thing and confirm the numbers in your own flow.
An Amazon staff member, in a thread about being ungated on items bought at auction, put it plainly: auction houses are often not recognised as authorised distributors or verified suppliers in Amazon's system. The rejection reason sellers get back is that the supplier cannot be verified.
Sellers in that thread had the right quantities, the right descriptions and full company details and still failed. The supplier type is the problem, not the document. Amazon is checking the supplier's relationship to the brand, and an auctioneer does not have one, so no amount of formatting fixes it.
The dangerous request is not the one at ungating. It is the one that arrives during an authenticity investigation, after a single customer complaint, and it asks for documents covering the units you actually sold.
A ten unit distributor invoice does not cover two thousand units of liquidation stock, and the volume mismatch is the flag. Ungating cleanly and then shipping auction goods against that approval does not solve the problem, it moves it to the account level.
Worth quoting exactly, from Amazon's own Code of Conduct: violations "may result in actions against your account, such as cancellation of listings, suspension or forfeiture of payments, and removal of selling privileges." Forfeiture of payments means money you already earned.
Clearing a category does not clear the brands inside it. Brand gates need a letter of authorisation, a whitelist, or a Brand Registry selling role, and they are enforced automatically. There is a documented case of a seller supplying the exact hundred unit invoice that was demanded and still being auto rejected, because the real gate was brand authorisation and no invoice could satisfy it.
Gating also resolves per account, across roughly five levels: item, brand, brand within a category, category, and sub category. No research can tell you whether your account is gated on something. Adding the product in your own Seller Central is a five minute check and the only authoritative answer.
These circulate in 2026 guides. We could not confirm any of them, and one of the sources contradicts itself. They are listed so you recognise them, not so you repeat them.
Inside, the suppliers, the loads and the checks get posted as they happen, including the deals that did not clear.
