Do Amazon barcods and manufacturer barcodes work together? How should we choose?

According to Amazon, sellers only need to choose between the manufacturer’s barcode and Amazon’s barcode. Here are a few things to consider when choosing a barcode:

  1. Whether the original product has the manufacturer’s barcode and whether it can be scanned.
  2.  Whether the category of the product matches Amazon’s barcode classification.
  3. Is shared inventory acceptable? If you want to use your own inventory to deliver orders exclusively, you can switch to Amazon barcodes at any time.
