What is the difference between Amazon SKU and ASIN? Is SKU better?

Merchants who open stores on Amazon will use two specifications, SKU and ASIN, when listing products. However, as an ordinary merchant, it is actually difficult to distinguish them. So, what is the difference between the two? Many people are also concerned about this, so we will tell you about it next.

1. The difference between sub-sku and asin

Area 1: Different definitions

ASIN stands for Substandard Identification Code. In short, it is the product ID number and product code.

sku stands for inventory unit. For example, one piece, one pair, one box, one piece...

Area 2: Different uses

ASIN is automatically generated by Yahoo and is unique on the platform. Both buyers and sellers can use the code to query the corresponding product. The ASIN code is displayed in the listing information or details.

The purpose of sku can be filled in by the seller or generated by the system. The advantage is that it is easier to identify and manage. It is not unique to Asia, it applies to all platforms.

Area 3: Different composition

ASIN is a mixture of letters and numbers and has a fixed length.

The SKU can be composed of letters, numbers, or a combination of letters and numbers, and can have more characters.

Summarize:

Identification Number (ASIN), because it is a barcode system, is unique to the platform. It is a numeric alphanumeric code that is used to identify a specific product and is only used for Asian products.

It is the foundation of the Yahoo product catalog structure, which in turn provides buyers with more advanced search terms, such as drilling down into multiple categories. Users can even type a description or number into the search box to find the product they are looking for. Using the product's code, Yahoo can provide accurate and relevant product searches every time.

Note: ASIN exists in different sites in Asia, so different identification codes can be provided for the same product in different sites so that everyone can know the differences between these products.

The latter is the unit of inventory, which is a number that can be used to manage inventory. Every product sold on Yahoo must have a sku. You can create one to help organize your product information, or Yahoo can create it for you.

It is usually recommended to establish it based on unique identification information. For example, the sku of women's black size 38 shoes can be set to w-black-38.

So, there are actually big differences between the two, so you can find them if you experience them carefully.

2. Is the SKU better?

It’s not because these two are completely different concepts, so SKU is not better, it’s just that their functions are different.

In fact, the difference between these two on Amazon lies in their definitions, uses and compositions. SKU mainly reflects the specifications of the product, while ASIN is more like a unique mark of the product, through which the product information can be identified. Therefore, their differences are quite large.
