Stickerless commingled inventory, explained in plain terms
Amazon still allows stickerless commingled inventory by default across many categories. Here is exactly how the system works, how to check whether a listing uses it, and how to opt out.
The term shows up constantly in seller forums, usually attached to a story about an unfair suspension, but rarely explained clearly on its own. Here is what stickerless commingled inventory actually means, mechanically, before getting into how it causes problems.
Quick answer
Stickerless commingled inventory means Amazon pools your FBA units with other sellers' units of the identical product under one ASIN, fulfilling orders from whichever unit is physically closest rather than specifically yours. Amazon still allows it by default for many categories, and opting out requires actively choosing individual unit labeling when creating a shipment.
How commingling actually works inside FBA
When multiple sellers list the identical product under the same ASIN and send inventory into FBA without individual unit labeling, Amazon's default system stores those units together in the same warehouse location, treated as interchangeable. When a customer orders that ASIN, Amazon fulfills it from whichever physical unit sits closest to the shipping point, without tracking which specific seller's batch that unit originally came from.
Does Amazon still allow stickerless commingled inventory
Yes. It remains the default storage method for many product categories unless a seller actively selects individual unit labeling during shipment creation. Amazon has not removed the option, and for high volume commodity products, many sellers still choose it deliberately because of the added cost that labeling introduces.
The exposure this creates
The tradeoff is that if even one unit in the shared pool is defective, mislabeled, or counterfeit, and a buyer or brand owner reports it, Amazon frequently cannot determine which specific seller's unit actually reached that customer. If a complaint has already been filed against your account this way, the appeal itself needs specific documentation and a different approach than a standard sourcing dispute.
How to check if a listing uses commingled inventory
Check your own FBA inbound shipment settings for that ASIN in Seller Central to see whether individual labeling was selected. If you want to confirm what a customer would actually receive, ordering the product yourself and inspecting the unit for a unique FNSKU barcode versus a manufacturer barcode is a direct way to see which storage method is in effect.
How to opt out
During inbound shipment planning, select individual unit labeling, sometimes referred to as the Amazon barcode requirement, which assigns each of your units its own traceable FNSKU. This keeps your inventory separate from other sellers' units on the same ASIN going forward, at the cost of a per unit labeling fee.
Frequently asked questions
What does stickerless commingled inventory mean?
It means Amazon pools your FBA units together with other sellers who list the identical product under the same ASIN, and fulfills orders from whichever unit sits closest in the warehouse, not specifically yours.
Is commingled inventory still allowed on Amazon?
Yes. It remains the default storage method for many product categories unless a seller actively selects individual unit labeling during shipment creation.

How do I stop my inventory from being commingled?
Select individual unit labeling, sometimes called the Amazon barcode requirement, when creating your inbound shipment, which assigns each unit its own traceable barcode instead of pooling it anonymously.
