When you create an Amazon listing from within Selro, if you have included an EAN/UPC in the listing, that doesn't exist in Amazon, then Amazon will create a new ASIN for that EAN/UPC when you list from Selro.

If the EAN/UPC already exists in Amazon, then Amazon will send us the existing ASIN when you create the listing.

You are also give then option to manually add an existing Amazon ASIN when creating the listing should you wish.

For any other questions regarding Amazon listing please feel free to contact our support team at [email protected]
