What Is a Walmart SKU? (A Comprehensive Guide)

What Is a Walmart SKU

As one of the world’s largest retailers, Walmart offers a vast array of products across its many stores. To help manage this extensive inventory, Walmart utilizes an SKU system. 

In this comprehensive guide, we’ll explore what Walmart’s SKU is and how to use it to quickly and efficiently look up items. So, keep reading to learn more!

What Is a Walmart SKU?

A Walmart SKU is a unique identifier assigned to each product that Walmart sells. This identifier is used to track inventory, sales, and restocking. SKU stands for “stock keeping unit,” which is a system used in retail to identify and track products. Think of it as a product’s ID number.

When you walk into a Walmart store, you will notice that products are arranged on shelves in a certain way. This arrangement is based on the SKU system. Each product is assigned a unique SKU number, and the products are arranged on the shelves based on these numbers. This helps Walmart employees locate and restock products quickly and efficiently.

How Does Walmart Use SKU Numbers?

Walmart uses SKU numbers to keep track of its inventory. Each product has a unique SKU number, which allows Walmart to track how many of each product it has in stock, how many have been sold, and when more need to be ordered. 

In addition to tracking inventory, SKU numbers are also used to help Walmart employees locate products quickly and efficiently. By knowing the SKU number of a product, an employee can quickly locate it on the shelf and bring it to the customer.

Finally, Walmart uses SKU numbers to track sales and analyze data. By tracking which products are selling well and which ones are not, Walmart can make informed decisions about pricing, marketing, and inventory management.

How Does Walmart Generate SKU Numbers?

To generate SKUs, Walmart uses one of the Point of Sale Systems, also known as POS. These systems are designed to help Walmart manage its inventory, track sales, and generate SKU numbers automatically. 

That way, when a new product is added to the inventory, the system will assign a unique SKU number based on the product’s category and other identifying characteristics. 

This helps ensure that each product has a unique identifier and that the SKU system remains organized and easy to use.

How Many SKU Numbers Does Walmart Have?

It’s difficult to say exactly how many SKU numbers Walmart has, as this number is constantly changing. That said, it’s estimated that Walmart has over 75 million SKU numbers both in its stores and online. 

With such a large number of products, it’s no wonder that Walmart’s SKU system is so important.

Can I Look Up Walmart Items by their SKU Numbers?

The short answer is yes, but not on Walmart’s website.

Although Walmart’s website provides a lot of product information, it doesn’t offer a direct way to search for items using SKU numbers. Instead, you can use a third-party tool called the Walmart Inventory Checker on BrickSeek to look up Walmart inventory using SKU numbers. 

This tool allows you to check the availability and price of products in Walmart stores by entering their SKU numbers. It’s a quick and efficient way to check the descriptions of products in Walmart stores without having to physically go to the store.

What Does the Walmart SKU Look Like?

The Walmart SKU is a unique code assigned to each item in Walmart’s inventory. The SKU is made up of a combination of letters and numbers, and it is usually eight digits long. 

For example, an SKU for a particular brand of shampoo might be “ABC12345.” You can usually find it on the price tag of the product or on the product packaging itself.

It’s important to note that SKU numbers are specific to Walmart and are not the same as UPC codes or barcodes.

What Does the Walmart SKU Lookup Process Look Like?

The Walmart SKU lookup process is relatively simple. 

All you have to do is open the Walmart Inventory Checker, enter the SKU number of the product you’re looking for, and hit “Search.” 

You’ll then be taken to a page that provides detailed information about the availability and price of the product in Walmart stores.

Is There a Difference Between a Walmart SKU and a UPC Number?

Yes. A UPC is a barcode that is used to identify products across different retailers and is often found on the product packaging.

For example, if you purchase a box of cereal from Walmart and then buy the same box of cereal from a different retailer, both products will have the same UPC. 

In contrast, a Walmart SKU is a unique identifier that is specific to Walmart and is used to manage inventory within the Walmart supply chain. 

As for visual representation, a Walmart SKU number is usually eight digits long and composed of both letters and numbers. A UPC code, on the other hand, is typically 12 digits long and is composed of only numbers. 

Is There a Difference Between a Walmart SKU and a UPC Barcode?

Yes. A UPC barcode is the physical representation of a product’s UPC code. It consists of a series of vertical black lines and numbers that can be scanned to identify the item and find its associated price. Meanwhile, a Walmart SKU is an internal inventory code that cannon be scanned.


Walmart SKU numbers are unique numbers assigned to products in Walmart’s inventory. You can use them to look up product descriptions, availability, and prices on third-party websites. They usually look like “ABC12345” and are eight digits long. 

However, they are not the same as UPC codes, which are 12 digits long and usually accompanied by a barcode. So, if you need to look up a product in Walmart’s inventory, make sure you use the correct SKU number.  

Happy shopping!
