Why am I receiving the error "Carrier/class lookup failed" on my ChannelAdvisor shipment?

When you create a label in ShipStation, we update ChannelAdvisor with a tracking number, carrier/service, and shipped status for the order. 

If you ship using a carrier and service that hasn't been added to your ChannelAdvisor account, you will receive an error when ShipStation attempts to submit tracking data for a shipment: 

"Carrier/class lookup failed."

You'd see this error if you were to click on the red shopping cart warning icon corresponding to the failed shipment.



Doing so will show you the Shipment Task Status pop-up.



In order to resolve the error, you must add the acceptable class and carrier codes in ChannelAdvisor. Check out this video or this article by ChannelAdvisor on how to add a new shipping carrier. Please refer to the attached spreadsheet at the bottom of this article for a list of all ShipStation shipping services and their applicable ChannelAdvisor carrier and class codes.

Once you add your carrier to ChannelAdvisor, you can go back to the Shipment Task Status pop-up again. If you need to get back to it, go to the Shipments tab, and click on the yellow warning icon next to the affected shipment.

At the Shipment Task Status pop-up, you can now click Retry Failed Steps to resend tracking information, which will remove the error.

If you have many shipments that need tracking information resent, please contact our support team for assistance.
