Adding your goods to Amazon is a good way to extend your client-base, selling more on one of the worlds biggest marketplaces. Making listings on Amazon.com website requires from the sellers to use product identifier to add new product. If the product is well-known and widely-sold, then most likely it already exists there, so you can simply map it. However, in case you are going to list the item you yourself developed, some exclusive goods or any of those which are not yet included on the site, you might stuck at one important point – unique Amazon product code.What is Amazon Product Identifier?If you think that you will be able to input any value for this, you are mistaken. Generally, it should be some officially documented, unique code given to your product, using which it can be recognized worldwide (used internationally to find product information across databases). In most cases, the common identifiers used by sellers are UPC, EAN, or ISBN. If you don’t provide any, generally, you will receive the error message stating that you are not able to proceed with listing the item without this information. More information on the mentioned product codes you can find here – http://www.amazon.com/gp/seller/asin-upc-isbn-info.htmlIs it Possible to Sell on Amazon without UPC/ EAN/ ISBN?There are some ways to place your goods at marketplace not having at your disposal any of the above mentioned codes to identify your products: – List Items to Categories That Do not Require CodesYes, on Amazon there are categories that do not require codes.

Sellers must be approved to list products in a category in order to request UPC/EAN exemptions for that category. Generally, sellers must have a selling history on Amazon.co.uk before they will be considered for an exemption. EAN exemptions cannot be granted for single ASINs sold in product bundles or in bulk. With the exception of “Antiques” products, the condition of an item for which an EAN/UPC exemption is requested must be “New”. Requests for UPC/EAN exemptions can be made by filling the EAN Exemption form.Source: http://www.amazon.co.uk/gp/help/customer/display.html?ie=UTF8&nodeId=201741190– Indicate Part Number Instead of UPC/ EANSome Amazon categories can accept part number as unique product identifiers.
