New sellers will be able to create only a limited number of listings until he has established a proven record of the sale of their product on Amazon. In simple terms, if your sales on Amazon increase, so is your capacity to make new ASINs for your products. Henceforth, if you want to increase your sales volume, you should prioritize the product you are listing. The more sales you have, the more ASINs you’ll be able to create.

How to create a new ASIN in Amazon

If you are a seller of a new product who is yet to create an ASIN and have no ASIN to boost, you must create a new ASIN to get listed in the Amazon catalogs. All the manufacturers and brand owners create new ASINs; however, the possibility is that one must always find a new product with very little competition. The advantage is that it can trigger up your chances of winning the Buy box and improve your chances of maximizing profits.

A new Amazon ASIN should be created in the following manner for your product:

  • First, go to the “add product” option on your seller central account. The steps for creating new ASINs may vary depending on the type of product category.
  • Next, you must choose the option that you are planning to add a product that is not being sold on Amazon.
  • Then you must search and select the category.
  • Usually, there are three main categories. After clicking on any one of the categories, the other will keep opening. This procedure keeps occurring until the one you wish to create appears. For example, if you open the category of personal care, it will further open skincare, cleansers, and so on.
  • Once you choose the desired category, a page appears, and the seller must fill in some required fields.
  • The seller must fill in all the blanks and later click on the “save and finish” option.
  • Once the seller submits the form, Amazon will assign the product a certain ASIN code and will publish the same on the product details page.

Since you are now using the existing ASINs, other sellers are also in a position to see the ASIN that you have created for your product.

What is Amazon ASIN Duplication

Amazon made certain norms regarding product ASINs of which, if a seller intends to sell a product in the catalog, then he must match the corresponding product ASIN number with the existing ASIN by making an offer. If a product already exists, then creating a new ASIN for the same is prohibited. Then, the seller will be curbed of certain selling privileges he enjoys. On the other hand, if the product is not listed in the Amazon catalog, then he must create a new ASIN.

The seller must always use an appropriate code, such as UPC (Universal Product Code), ISBN (International Standard Book Number), and JAN (Japanese Article Number), while listing a product to avoid duplication of ASINs. Japanese Article Number (JAN) is a barcode standard compatible with the EAN.

How to use an existing Amazon ASIN

For retailers and resellers, the best thing is that they can use the ASINs which are already in existence for their product listings. However, as discussed earlier, there is an ASIN duplication policy, but the use of existing identifiers has its advantages. Instead of making a duplicate list, if one matches an existing product, then it will get the buyer’s interest and traffic.

When a list is created through your Seller Central account, one can search for existing ASINs by typing a product’s name, model, ASIN, etc..

After getting the result, the next step is to choose a listing under which a seller wants to sell the product and later add the necessary information, which will be crucial. If multiple ASINs appear to exist, the seller must choose the one with the relevant product details. But it must be made sure that he chooses the exact match while selecting ASIN for his product. On the other hand, if the customer’s order does not match the one they receive, it may lead to a negative impact.

What is the process of adding unique Amazon ASINs with ISBNs, EANs, and GTINs

When creating a new ASIN for your product, you should be aware of your product’s GTIN (Global Trade Item Number). To create and match the ASINs, Amazon makes use of 14-digit unique product identifiers. These identifiers are located near the barcode of the product. If you are unaware of this code, you must contact your manufacturer. You must complete your product registration with the GTIN code if you are the manufacturer.
