Overview

You’re required to provide valid tracking information to Walmart as soon as you’ve shipped a Marketplace order and marked the order as Shipped in Seller Center or via Walmart APIs. In this guide, you’ll learn more information about our tracking policy.

What is the policy?

Prior to shipping the item, you’ll need to give your shipping carrier authorization to provide shipment tracking data to Walmart. You must provide valid tracking information to Walmart for at least 99% of your shipments. Per our Seller Performance Standards, if you provide invalid tracking or fail to meet the 99% standard, it may result in selling restrictions, suspension or termination.

Pro tip

You can’t use stamps or pre-paid envelopes to ship orders. 

Additional guidelines

Tracking numbers must meet the following requirements:

Correct formatting.
No special characters (e.g., ~ ` ! @ # $ % ^ & * ( ) _ - + = { [ } ] | \ : ; " ' < , > . ? /).
Contains a valid link that customers can use to track their package on the carrier website.

Has at least one valid carrier scan on record.

What shipping carriers does Walmart support?

Your tracking number must be generated from a list of supported carriers. Consider using large, reputable carriers to fulfill your Walmart orders. You can see the list of freight shipping carriers here and a list of parcel shipping carriers here.

If you’re using small or regional carriers not integrated with Walmart, you may not meet the 99% valid tracking requirement. Don’t select More Carriers in place of supported carriers. Don’t use competitors’ delivery services. Non-compliance may result in selling restrictions, account suspension or termination.
