What is a seller SKU on Amazon?

SKUs are used in warehouses to keep track of items.

SKUs are specific alpha-numeric codes assigned to each of your products and variants, and they’re commonly found in warehousing systems.

An SKU can be made up of any combination of letters and numbers you like if the system is consistent across all your inventory items.

An SKU for Amazon sellers has the same restrictions. However, each SKU may only be up to 40 characters long.

All goods available on Amazon must have SKUs that you can generate or have Amazon generate for you. Sellers should use Amazon SKUs to keep track of their products.

Note: The code for a product is not the same as its SKU. The term “stock keeping unit” refers to the identifying number that identifies each one of something. Products are assigned an eight-digit UPC or a thirteen-digit EAN, their unique identification number worldwide.

What should you include in an Amazon SKU?

In most cases, all SKUs should include information that aids in the purchasing process:

  • Categorize items by colour, size, and type.
  • Products may be picked, packed, and sent from the warehouse quickly.
  • Inventory that is being sold across multiple channels must be tracked.

When creating your Amazon SKUs, include product identifiers that may help consumers locate you on the site.

Consider including the following items:

  • Product identifier.
  • Model/style identifier.
  • Colour identifier.

Tip: Amazon seller SKUs will be the most prevalent SKUs your company will handle for items; adding an identifier for where the product is being sold may also be helpful. Including an indication in this scenario, such as “AM”, is a good idea. And all future new items should use the same SKU format.

Examples of Amazon SKUs

Merchant-generated SKUs differ from Amazon SKUs depending on the business’s internal standards. What these rules look like is dependent on what you’re selling.

Here are some examples of Amazon SKUs and how they function.

SKUs Based on Product’s Title

Take the first letter of each component in the title and turn it into your Amazon SKU number, for example, if your product is Cisco 3560-CX Switch. The SKU in this situation will be C3S.

SKU Based on a Product’s Attributes

For example, if your product is called Catalyst PON 4-Port PoE Voice-Activated, the Amazon SKU number will be changed to P-4P-P-VA.

SKU Arranged Based On The Importance Of Variables

For example, a product named “Premium Boar Bristle Beard Brush – Real Wooden Handle” might have an SKU like PR-BB-BB-RWH.

This SKU organizes the product’s most important features in order of significance. The fundamental components appear first in the SKU section. The rest are towards the end of the description.

What is an Amazon ASIN?

Amazon creates and attaches an ASIN number to every physical item in its catalogue. That isn’t the seller’s SKU, though.

An Amazon Stock Identifier Number (ASIN) is a 10-digit number assigned to every Amazon product. It’s a unique identifying number that allows them to track all the items they sell on Amazon. Think about how many things there are.

ASIN Amazon

You won’t have to worry about that number because Amazon assigns the Amazon ASIN to all physical items. Howewon’tyou must you create and manage your seller SKU or MSKU for each item you send to the Amazon warehouse?

What is an Amazon MSKU?

The Merchant Stock Keeping Unit, or MSKU, is a term used to describe the Amazon seller SKU.

It’s the fancy and expensive number you use toIt’s a product for sale on Amazon.

For example, consider the following MSKU:


It’s just a collection of numbers and letters from the customer, but it holds a wealth of knowledge for you as a seller.

It’s also important to note that the SKU andIt’sKU are different. The SKU is an identifier used in a warehouse or retail setting, while the MSKU is what you use on Amazon.

What is an Amazon FNSKU?

The MSKU and FNSKU sometimes get confused. If you operate an Amazon FBA business, both identifiers will be associated with your goods.

That’s because an MSKU distinguishes your pThat from everything else selling the same thing inside Amazon’s fulfilment centres. In contrast, an FNSAmazon’snguishes yours from all other sellers.

Here’s an example of an FNSKU label that wouHere’splaced on a product and sent to Amazon’s facility:

FNSKU Amazon

Why should you manage yoAmazon’sn seller SKU carefully?

If you submit a popular book to Amazon for resale, other vendors will also offer it. As a result, to properly distinguish your work from the many other seller’s titles in the warehouse, you’ll neseller’seller SKU or FNSKU.

You’ll not only maintain an accurate inventory but also for how Amazon knows they’ve sold youit’sok and not your competition.

How to make your seller SKU competitions are five different methods to acquire your own Amazon seller SKU:

  1. Source Identifier: Keeping track of where your iIt originated is critical. If you notice things flying out the door from Craigslist (CL) and all of your purchases from Walmart (WM) accumulating, where will you most likely seek more supplies?
  2. Product Identifier: For example, the cover photo of a book may resemble the front of a CD and vice versa. If you have a lot of CD descriptors in your item sales, you’ll know immediately, without seeing you’ll, that you’re selling a lot of CDs, and it’s time you’re more.
  3. Date Identifiers believe that one of the most crucial ways to personalize your Amazon seller SKU is through product timing. If you see a lot of goods selling on April 1st that was sent in November, then there are certain patterns to be seen either with the item itself or with the sale’s date.
  4. Condition Identifier: This is a sale critical since the sales velocity compared to the product’s condition is crucial for future sproduct’srips. Are new items selling better than used ones? Perhaps it’s time to source differently and stock its NEW stuff instead of other conditions.
  5. Cost Identifier: This is not essential to your business since you already know how much you paid for the item when you sourced it, but it may put a grin on our face every time you sell a CD for $10 or more, and your SKU claims that you purchased it for $50.
