Update SKUs in bulk in Seller Center
Last updated on Feb 27, 2025
Reading time: 2 min
Overview

When you set up your items on Walmart Marketplace, each item’s product identifier is associated with a single SKU. If you need to update the SKUs for one or several items at once, follow the steps below.

Update SKUs

Step 1 — Get started

Navigate to your Catalog in Seller Center and select the Add items button. Select the Upload in bulk link located under Add thousands of items using a spreadsheet. On the next page, select the Create new items button.

Notes

You must select the Add items button to download and complete all the attribute requirements in the template to update your SKUs. 

Step 2 — Download and complete the template 

Select the product categories for the items you want to update the SKUs for, then choose Next. Then choose up to 10 product types. Once you’ve chosen your product types, choose Next. Finally, choose Seller fulfilled as your preferred fulfillment option. When you’re ready, select the Download button in the bottom right corner of the page. 

Notes

If you need to change the SKU for a Walmart-fulfilled item, you’ll need to retire the item and set it up again before republishing the item on Walmart.com. Once the SKU is updated, select the Help button in the Seller Center menu bar to contact Support so we can have our fulfillment centers relabel your items.

In the template, fill in your updated SKU and all the other required fields and item attributes including the column labeled SKU Update. The SKU Update column is located in the Optional section of the template, but you must choose Yes from the dropdown menu for the SKUs to successfully update.

Step 3 — Upload the completed template

To upload your completed template, navigate to your Catalog in Seller Center and select Add items. Select the Upload in bulk link located under Add thousands of items using a spreadsheet. You can drag and drop your file onto the browser window under Upload, or select the browse link to locate the file on your computer.

Updates can appear in as quickly as 15 minutes or can take up to four hours.
