What is ASIN?

Amazon Standard Identification Number or the ASIN is the standard that your products are identified on the Amazon marketplaces. These ASINs are unique for each product but on different Amazon marketplaces, these could represent different products.

What to do when I don’t have GTIN to list products on Amazon?

This is the case that most retailers face while starting to sell on Amazon. The first place that you should try it is with the manufacturer of the product. If the product manufacturer cannot provide you with the GTIN codes for the product you can go ahead and register the UPC codes for yourself.

Please note that you will need different UPC codes for every variant of the product so it is better that you don’t just purchase one code but please buy the codes strategically. Here’s a link that you’ll find useful to buy the UPC codes.

Most of our clients are also willing to go through the lengthy process of GTIN exemption while listing their products on Amazon. However, the GTIN exemption cases are mostly time and effort consuming, and even when one goes through the process, it takes time and you cannot be sure whether you’ll be awarded the exemption.

Can Amazon Brand Registry program help?

Next way that you would create a workaround for your GTIN is the Brand registry with Amazon. However, you’ll need a registered trademark for your brand. And, the products should be packaged with the branding of your registered brand. Then you can apply to register your brand on Amazon. This is by far the easy way but it can also work for GTIN exemption.

Now looking at the options,

  • Buying the UPC codes is the easiest way and it becomes cost-effective also if you buy the UPC in bulk and it guarantees certainty for product listing.
  • Applying for GTIN exemption will be cost-less but it is time-consuming. You may or may not be able to get the exemption.
  • Amazon brand registry is a beneficial program if you are only planning to sell on Amazon, but still, it is also time and effort consuming process.
