Frequently asked questions

Overview

Each product identifier in your catalog can be associated with only one SKU. If, for example, you uploaded the same SKU with a different product, you would get an error and vice versa. In this guide, you’ll learn how to update a product ID.

Notes

If you need to change the product ID 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 product ID is updated, create a case for Seller Support with the information so we can have our fulfillment centers relabel your items.

Update product IDs

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.

Step 2 — Download and complete the template

Select the product categories for the items you want to update the product ID for, and 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.

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

Step 3 — Upload the 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.

Frequently asked questions

I accidentally uploaded the incorrect product ID, what should I do?

What should I do if there is an error in my item's listing because the content has been provided by another seller?

First, check your spec to ensure that you are using the correct product ID for your item. If your product ID is incorrect, follow the steps above to provide the correct product ID. If your product ID is correct, please create a case for Seller Support.

If you suspect their product ID is incorrect, provide the product ID of the item and a way for us to verify that your product ID is correct (e.g., a photo of the packaging that shows the item and its associated UPC).

If the other seller's product ID is correct but some of their information is wrong, please provide us with the product ID, the field that is incorrect (e.g., description, key features, image), why this field is incorrect, what you believe this field should read and a way for us to verify that your information is correct (e.g., scan of instructions, a link to the item on the manufacturer's website with full details).

Seller Support will then take the necessary steps to resolve the issue.

Update item content individually in Seller Center

Catalog management

If you need to quickly update your item’s content, you can do so right from the Items dashboard in Seller Center. However, because there may be multiple sellers providing content for the same item, you may not always be able to define which content will be displayed on Walmart.com.
