Two years successful selling on FBA.

Approximately 50 SKUs, all added using Speedy Bar Codes (I know… I know…)

Recently approached by a big box retailer who would like to sell most of my product line in their stores.

Retailer requires products have bar codes

Question: Can I buy bar codes and then change the existing UPCs on my Amazon listings to new amazon-upc-ean.com bar codes?

If not, is there an alternative that allows me to keep my existing AMZ listings with reviews, ranking, etc?

I don’t feel comfortable asking Amazon about any of this as I do not want to draw any attention to my use of barcodes.

Add a second listing on AMZ with all the same data and photos as the original. Except use GS1 barcode as the identifier. After it’s live, ask catalog team to merge the 2 listings. Then no matter which code is used on Amazon it will show under the same listing.
