What is an Amazon ASIN number?

ASIN is an Amazon Standard Identification Number.

Amazon ASIN codes are automatically assigned to each listing you create on Amazon.

Thus, listings or products are often referred to as ASINs. ASINs always start with “B0” and are ten digits long. Amazon ASIN codes identify a product or listing on its site, and you can find them on the item’s product details page. An ASIN is created for all products when they are added to Amazon.

Codes for Amazon products

Due to the fact that Amazon sells millions of products, it’s no surprise that they have created their own internal barcodes to keep track of them – ASIN, FNSKU, and SKU. Identifying and categorizing products quickly and accurately is essential for ensuring a smooth, efficient supply chain, which can only be accomplished through such codes. Furthermore, these codes contribute to high customer satisfaction levels, since customers get what they ordered.

I hope this offers your query to What is an Amazon ASIN number.

What is an FNSKU?

FNSKU is a Fulfillment Network Stock Keeping Unit.

Fulfilled by Amazon (FBA) listings are assigned an FNSKU. You should supply Amazon with an FNSKU barcode for every unit you send in since this allows Amazon to be able to track where the inventory has come from.

A mistake on one of these could lead to a lot of headaches, including sending the wrong product to customers. Make sure these are complete and accurate. This can result in negative reviews and negative feedback against your seller account as well as damage to the listing.

In addition, FNSKUs must start with “X0” and contain ten alphanumeric digits. When your FNSKU labels do not begin with “X0”, you are about to send inventory to Amazon, and you need to fix it immediately and correct the barcode before any issue arises.

What is an SKU?

SKU is a Stock Keeping Unit.

It is the only identification number that identifies a seller, you can use to identify your product, and is different for each marketplace. It is a unique number that identifies you, as the seller. Some sellers offer different packaging for different SKUs on different marketplaces for the same product (ASIN). Despite being able to create their own SKU within Amazon, and possessing their own SKU labeling and tracking system. The concept of SKUs cannot be attributed exclusively to Amazon and may be used by other inventory tracking systems as well.

SKUs are not changeable once they are created, and Amazon will randomly create an SKU for your listing if you do not enter one, so make sure you choose this carefully. If you resend the same shipment to Amazon, you may create a new SKU, but the inventory will have a new offering.

Universal standard codes

In addition to Amazon, universal barcodes are used globally in many other businesses. Even so, they remain very important to Amazon sellers for finding products quickly and accurately in an extensive database. Let’s learn what are some important universal standard codes.

What is a GTIN?

GTIN is a Global Trade Item Number.

The Global Trade Item Number (GTIN) is an identification code for-trade items created by GS1 – Global Standards 1. These codes are used to identify items within databases. The number is usually entered by scanning a barcode on the product, which is either owned by a retailer, manufacturer, collector, or researcher.

The uniqueness and universality of an identifier facilitate cross-referencing between products in one database and those in another, especially when the databases are separated by organizational groups.

What is a UPC?

UPC is a Universal Product Code.

In retail stores and online marketplaces worldwide, UPCs are used to identify products, and no two UPCs are identical. Most products must have a UPC before they can be sold on Amazon, according to Amazon Seller Central.

UPCs have 12 digits and are unique to a single product, so scanning a barcode or examining a UPC easily identifies each product. There are some countries that require that sellers provide UPC barcodes for each product they sell. To be clear though, if 1000 units of the same product are being sold, there is no need for 1000 different UPCs, you only need one, and that one label goes on all 1000 units which are similar.

What is an ISBN?

ISBN is an International Standard Book Number.

The new generation of Amazon sellers may be surprised to learn that when Amazon initially started out in 1994, the only products they could sell were books! As a result, ISBNs were among the first barcodes you would see on Amazon at that time. Each book published around the world has its own ISBN.

There are two types of ISBNs: 10 and 13. After January 1, 2007, all ISBNs have 13 digits. ISBNs are typically printed on the back cover of books. Self-publishing on Amazon, which issues ISBNs automatically for each book published on their platform, is the same as self-publishing with a publisher.

What is an EAN?

EAN is a European Article Number.

UPCs look similar to European Article Numbers, but the difference is that European Article Numbers have 13 digits instead of 12. The country of issue or type of retail is indicated on the EAN code by the addition of a digit. EAN barcodes are unique to a single product, just like UPCs.

  • Additional product codes

MPNs and IPNs are two additional codes you may encounter as an Amazon seller. Both of these codes correspond to part numbers, but we can distinguish them according to how they are assigned. 

What is an MPN?

Manufacturer Part Numbers are known as MPNs. MPNs, or manufacturer part numbers, are alphanumeric values that are assigned by the manufacturer to identify a product in the same line of products.

You may also consider this the catalog number of your supplier. Your supplier will be able to identify your product without confusion when you refer directly to the catalog numbering system of the supplier. You help your supplier understand what you are trying to order if you both speak the same language.

What is an IPN?

IPN stands for Internal Part Number.

Keeping track of your inventory is made easier using internal numbering systems. The numbering system can be assigned by establishing a specific naming convention that helps make identifying your products easier.
