So I started using USPS Ground Advantage shipping through XPS Ship and then pasting the tracking numbers into Shopify (since Shopify does not even support printing Ground Advantage labels).
But the problem I am having is Shopify incorrectly identifies them as DHL eCommerce tracking numbers, forcing me to manually switch the carrier to USPS every time.
I contacted Shopify support but was basically told I must be doing something wrong, when clearly the issue is Shopify’s automatic tracking number recognition algorithm. How do I get through to someone there who can actually fix it, when they won’t even admit that it’s a problem with their website?
I encountered the same challenge where Shopify was misidentifying USPS Parcel Select as DHL.
To resolve this, I adjusted the custom mapping within our API. If you can access your API, inspect how the fulfillment field is mapped.
Specifically, ensure the “fulfillment.tracking_company” field in Shopify correctly aligns with your shipping method. I established a direct mapping from our ERP’s “Ship Via” to Shopify’s “fulfillment.tracking_company”, creating a static mapping for our systems.
For example, ERP: Export Value: USPS Parcel Select // Shopify Import: USPS. This way, Shopify doesn’t misinterpret the shipping company.
