Commingling practices will end effective March 31, 2026
In March, we’ll end commingling practices across our supply chain and update eligibility criteria for using manufacturer barcodes.
Commingling is when we fulfill customer orders using exact product matches from the closest available inventory in the Amazon fulfillment network, even if that inventory belonged to a different seller, to achieve faster delivery speeds. Now that most sellers maintain inventory levels that keep products close to customers, we can achieve fast delivery without commingling.
The following requirements will go into effect for inventory shipped on or after March 31, 2026:
- Brand owners with the Brand Representative selling role in Amazon Brand Registry will no longer need to apply Amazon barcode stickers to prevent commingling for products that already have manufacturer barcodes (such as UPC, ISBN). This means more flexibility in how you manage inventory because you will not need to pre-allocate units to Amazon or other channels. For more information, go to How to switch to manufacturer barcodes.
- Resellers (not enrolled in Amazon Brand Registry as a Brand Representative selling role) will now be required to use Amazon barcode stickers for products even if they have a manufacturer barcode. If you are already using these stickers, you can continue to follow your existing process.
- For products that do not have a manufacturer barcode, both brand owners and resellers will need to use Amazon Barcode stickers.
For more information, go to FBA barcode choice and labeling FAQ.

About time.
Hopefully this will help with some of the counterfeiting problems or used sold as new complaints.

will this include items that require an expiration date?

Was anyone actually using this anymore anyway? I feel like those who were probably got banned for counterfeits that were not theirs or some other violation because of other people's inventory.

Just to clarify, sellers can continue to send in manufacturer barcode/commingled up until March 31st? Also what happens after March 31st with the leftover commingled inventory that’s already there? @Dougal_Amazon

Hi,
How do the changes affect resellers - not brand owners - who are enrolled in Brand Registry with a Brand Representative selling role?

Recently I have been unable to use manufacture barcoding on products with a UPC that has been assigned to multiple ASINs. I assume this is in preparation for these changes, as it's only started in the last two months. An example would be 035965048279 which is assigned to B004ZSSLD6, B00IOXJIB2, B01M9B8ZD1, B00002N5PX, B00C3IHDXO, B00DF3K932, B01HH23BTA. Will these changes help in this situation?

What I wonder is why require FNSKU labels for all non Brand Representative sellers when Amazon can track the history and ownership of the SKU via bin location. The amount of waste virtual tracking (UPC tracking instead of FNSKU) prevents is meaningful. All of the paper labels and plastic paper backings add up. Why not afford sellers with 1,000 AHR the privilege of continuing to use UPC / virtual tracking instead of FNSKU labeling?
I also wonder why virtual tracking / commingled inventory is not available to accounts with the "Reseller" selling role in Brand Registry. Based on the benefits "Reseller" Brand Registry roles afford, it shows a high level of trust between the brand owner and the seller. "Reseller" role even allows you to edit the Brand Store, which clearly shows the brand owner has faith in the seller they gave the "Reseller" role to maintain strict standards of quality and professionalism.
I request Amazon consider, at the very least, allowing "Reseller" roles within Brand Registry to continue using virtual tracking / commingled inventory.

Brand owners inventory shouldn't have been commingled with any other resellers in the first place especially since these resellers DO NOT have the brand owners (us) authorization to sell our brand/products.

Why in the world would those with Reseller status in the Brand Registry not still be able to do comingled?
This is super wasteful. I will now have to label thousands of products by hand costing lots of $ and time for that labor.
This also coincides with Amazon removing prep, so I cant even pay Amazon to label them.
This makes the Reseller role in Brand Registry basically worthless. You can create products, but anyone can sell on the listing, so yeah... worthless.

To double confirm, if a shipment with manufacturer barcode/commingled was set up before 3/31, but had a later eta then 3/31. Would the units with manufacturer barcode in this shipment still be properly received? Or they would automatically be identified as defective and pulled away?
