Amazon ASIN

You may wander around the website and see the word ASIN. Perhaps, this particular requirement is asked of you. No matter when you first hear about it, you will encounter an ASIN number.

What is an ASIN, and what is an ASIN number? An ASIN number is composed of 10 letters and numbers that are assigned by the website and its partners for product identification on the database.

You might also wonder, “What does ASIN stand for?” or “What does ASIN mean?” ASIN stands for Amazon Standard Identification Number. All products on Amazon have a unique ASIN. In other words, no two products have the same Amazon Standard Identification Numbers. This identifier is a big help to customers who want to find a particular product. It’s also used for indexing catalog pages. It helps narrow down the search for its customers in finding particular products to their liking or needs. It also helps in tracking the product during inventory, whether it’s about its location within the warehouse itself or to the places it’s been. Lastly, it’s used in reference to the catalog page of the product.

The easiest and fastest way to find the Amazon ASIN number of a product is in the address bar of the product you are planning to sell. It will be located after the name of the product and “dp”. You can also locate the ASINs in the product details towards the bottom of the page. You can also use an ASIN lookup tool like Synccentric to import the identifiers of your products then get the ASINs for you, making the job easier. Usually, ASIN lookup tools may cost money depending on how much workload is required.

You may also see if the product you are planning to sell needs an ASIN number on Amazon. This indicates that the product is not yet available on the Amazon website. You can use this to your advantage. You can research whether or not your product is unique. Then, you can size up your competition.

The need to create a new ASIN code indicates that you are the only seller that sells your product on the website. It is important to be able to create, maximize, and use the right ASIN code for your products, or it may lead the Amazon website being unable to find your products and not be able to display them to potential buyers.

Accompanying the creation of a new ASIN, it is necessary to familiarize yourself with GTINs or Global Trade Item Numbers of your product. These can be easily found by the barcode of your product. Remember that the Amazon website always uses these essential identifiers for easy accessibility for both the company and its shoppers.


Another identifier that you will encounter is GTIN. GTIN means Global Trade Item Numbers. It is composed of 12 digits in the United States but around 13 digits outside of the North American region. It can also be composed of 8 digits when it comes to really small products. This is needed to be submitted to Amazon as it is a standard product identifier.

As a seller, you are required to use this code to match universal industry standards. It is located on the packaging of the product or the product itself. In cases that the GTIN cannot be located, contacting the supplier or manufacturer of the product should be apt. Manufacturers should check out the GS1 standards website for guidelines regarding GTIN. Not all products are accompanied with the GTIN, made-to-order or handmade products are some exceptions.

All products to be sold on Amazon should have a unique trade item code. Certain cases of products packaged in many quantities but quantified as a single product should both possess different GTIN. This also applies to products that combine with another distinct product. For other guidelines, visit Amazon’s bundle guidelines for more information.

Amazon accepts all types of GS1 GTINs, so it would be best to adhere to the organization’s websites for smoother process transactions in starting out. You should also pay the GS1 website to see products that are exempted and considered exceptions. The barcodes, whether EAN, UPC, or GS1 GTINs, are used worldwide as they are already used as a standard. The organization will provide you a one of a kind company prefix that generates your GTINs. The prefix is annually licensed to you and comes with a fee that has to be paid as well.

Identifying your products always comes with the renewal of your license. You yourself will manage the data of your products with your company prefix. Applying for the company prefix is a fast process that takes only minutes on GS1’s website. Once you have received it, accompanying your company prefix is the 100,000 GTINS. Assigning codes will become a breeze, Moreover, you can sign up for many products. The GS1 organization’s website contains all the needed information for your preparations in starting a business venture with Amazon.

There are different types of GTIN, depending on the type of product you have, Some of the common types of GTIN are EAN or European Article Number, ISBN or International Standard Book Number, and UPC or Universal Product Code.

  • EAN or the European Article Number is a standard for barcodes, composed of 12-13 digits as a product identity code. This code identifies what the product is, its attributes, and its manufacturer. It is usually located just below the barcode of the product. It is also usually 13 digits for products transacted outside of North America and 12 digits for products within a specific region.
  • ISBN, also known as International Standard Book Number, is a universal product code for books put on the market. They compose of 10 or 13 digits, but books assigned with ISBN after January 1, 2007, have 13 digits. It is usually located above the barcode and/or on the back of the book. Book publishers should check out the U.S. ISBN Agency website for ISBN guidelines.
  • UPC or Universal Product Code is a 12-digit product code, similar to EANs, that identifies retail products in the United States and other North American countries. The difference between UPC and EAN is that UPC is widely used in North America with 12 digits. On the other hand, the EAN is composed of 13 digits, primarily used by the rest of the countries outside of the North American region. Primarily, both do the same job, so having either one is sufficient. For certain conditions that the EAN or the 13 digits are needed, adding a zero before the UPC or the 12 digits will work.

Amazon SKU

You can come across another identifier on the Amazon website– the SKU code. You ask yourself the questions, “What is an SKU number?” and “What is an SKU?” The SKU was initially for managing SKU inventory to track the whereabouts of individual items in a warehouse and the places it travels to. It can also track when it leaves the premises of the warehouse.

When on Amazon, the SKU is used to identify items and keep track of where they are. This is done to avoid confusion and mishaps with items when tracking products within the warehouse and outside of it.

You will also ask yourself, “What does SKU mean?” or “What does SKU stand for?” SKUs means Stock Keeping Units.

Amazon SKU codes can reach up to 40 characters. A stock keeping unit is a vital part of setting up an inventory management software. You can use an SKU generator online to generate SKUs that can help you out in creating a unique code assigned to your product. It would be of great help to create SKUs that work and are convenient for you.

One component or factor that can be used in generating SKUs for your product is the model numbers. SKUs are of big help in running your business with many factors such as using it as a marketing strategy. Moreover, you can personalize your own products to what you and your business needs. There are many features you may include in creating your SKU barcode:

  • You can add the identity of the product– what it specifically is, its own attributes, descriptions, its model numbers, etc.
  • You can add your supplier or manufacturer. This feature will help you distinguish the manufacturer or supplier of your products. This is most useful when you get your products from various sources.
  • You can add the date of the product. This would help you if your products come seasonally. It’s also used in progressing the demands of the product at a specific time.
  • You can add the location to your own warehouse or inventory for easy accessibility.
  • You can add the condition of the product. Differentiate if the item is brand new or secondhand or used.
  • You can add the cost of the product. Here you may see how the demand of your product progresses, depending on your strategy regarding how you price your products.

Additionally, most Amazon sellers include MPN that provides more accuracy in item listings and information about products, for example, technical specifics. Besides, it makes the goods comparatives more correct while eliminating any guesswork at the same time. What does MPN mean? Read our blogpost to learn more.

Buy Box

Buy Box is a unique system that identifies what exactly to offer to a particular customer. Thus, the buying process is easy. You just click “Buy Now” or “Add to Cart.” One Amazon Standard Identification Number has one Buy Box.

As for the Stock Keeping Unit, it can compete for the Buy Box with other product offerings. Do you have more than one active SKU? That means that they will all compete for the Buy Box.

If you want to sell one of the assortment items of the product, then immediately after the price has been reduced by a little, you will see the Buy box.

What if the price is the same, but one Stock Keeping Unit is FBM, and the other is FBA? In this case, the FBA SKU wins.

Okay, what if there are two Amazon FBA SKUs at the same price? The offer wins, which at the moment is closer to the buyer (in the nearest warehouses in stock). Thus, the buyer will receive the order soon.

What happens if the SKU is inactive? If Amazon does not have information about the exact date of receipt of the product at the warehouse, then it is not in the Buy box rotation.

Sometimes there is no Buy Box at all. Sometimes it happens that the field is missing in new accounts. How to activate? If you have the opportunity to contact specific managers, they will start it.

Reviews, Descriptions and Other Data

All this information is at the ASIN level. In other words, the number of SKUs does not affect the descriptions.

Removing a product from Seller Central will remove the SKU, not the ASIN. To suggest changes, you can change your listing details using Seller Central. The application of the changes depends on whether they have priority over other merchants. If the program did not make the changes automatically, contact support.

Amazon PPC (pay-per-click)

Since Amazon PPC is at the SKU level, you enter the SKU when you create your company. That is because the seller is promoting the offer itself, not the listing. If the SKU loses the Buy Box, then it is unusable for advertising. Consequently, buyers do not see offers, and you do not spend money on advertising, respectively.

To Wrap Up

Overall, the product SKU would bring a lot of big help in executing various jobs in your business. This can help oversee the demands of particular products, the organization within your inventory, already having an existing system of SKU naming when you add a product and many more.

The use of the ASIN, GTIN, and SKU are great innovations and easy accessibility in integrating to various marketplaces, from retail stores to couriers. These identifiers are essential in paving your way of business in online marketplaces. Marketplaces like Amazon develop their database in handling information with regards to an inventory of their products. This would ensure smooth handling and transactions. It also provides a structure on data about their products on the website for a better shopping experience for the customer. This can also help with product reviews and provide offers to customers.
