Moving from FNSKU to Manufacturer Barcode

Hello @Seller_zo2N7rA2UCEns

Christine here from Amazon Forums.

Transitioning from FNSKU (Fulfillment Network Stock Keeping Unit) to UPC (Universal Product Code) barcodes for your Amazon listings is a common step for sellers expanding to multiple platforms.

Here's a step-by-step guide to help you make this change while minimizing the impact on your product rankings:

Obtain GS1 UPCs:

Ensure you have legitimate UPCs purchased from GS1 for each of your products.

Update your Amazon listings:

Go to your Seller Central account

Navigate to "Inventory" > "Manage Inventory"

Select the product you want to update

Click on "Edit" and go to the "Offer" tab

In the "Product ID" section, enter your UPC

Save the changes

Create a removal order:

Remove existing inventory with FNSKU barcodes from Amazon's fulfillment centers

You can do this by creating a removal order in Seller Central

Update your product packaging:

Work with your manufacturer to update your product packaging with the new UPC barcodes

Send in new inventory:

Create a new shipment with your updated products bearing UPC barcodes

Send this inventory to Amazon's fulfillment centers

Monitor your listings:

Keep a close eye on your product listings for a few weeks after making the change

Watch for any unusual fluctuations in ranking or sales

Key points to minimize impact on rankings:

• Don't create new listings. Update your existing listings with the new UPC information to preserve your product history and rankings.
• Try to make this transition during a slower sales period for your products to minimize potential disruptions.
• Ensure you have enough inventory with new UPC barcodes ready to ship to Amazon before removing old stock to avoid stock-outs, which can negatively impact rankings.
• If there's any visible change to your product (like updated packaging), consider informing your customers through product images or description updates to maintain transparency.
• If possible, consider transitioning your products one at a time or in small batches, rather than all at once. This allows you to monitor and address any issues that arise without risking your entire product line.
• Keep your prices and product content (title, bullet points, description) consistent during the transition to avoid any algorithm fluctuations.
• Be prepared to handle any customer inquiries or concerns that may arise due to the change in barcodes or packaging.
