At Warehut, we make it easy to set up your preferred shipping methods in Shopify. Here’s how it works.
📦 Setting default shipping methods
You can configure a default domestic shipping method and a default international shipping method for all shipments.
To set or update these defaults, please contact your customer service rep.
Once set, you can call your shipping methods anything you like in Shopify (e.g., “Free Shipping,” “Standard Shipping,” etc.).
If no match is found during order processing, the system will fall back to the default method based on whether the address is domestic or international.
Important: If the default domestic shipping method is a UPS method and the shipping address is a PO Box, we will automatically select a comparable USPS method instead because UPS does not deliver to PO Boxes.
🤔 How shipping method mapping works
If you want to map specific Shopify shipping methods to carriers, the following options are available:
Domestic (US) shipping | Maps to… |
Any title containing “UPS Ground” | UPS Ground (USPS Ground Advantage for PO Box) |
Any title containing “UPS 2nd Day Air” | UPS 2nd Day Air (USPS Express for PO Box) |
Any title containing “UPS 3 Day Select” | UPS 3 Day Select (USPS Priority for PO Box) |
Any title containing “UPS Next Day Air Saver” | UPS Next Day Air Saver (USPS Express for PO Box) |
Any title containing “UPS Next Day Air” | UPS Next Day Air (USPS Express for PO Box) |
Any title containing “Priority” | USPS Priority |
Any title containing “Express” | USPS Express |
Any title containing “Ground Advantage” | USPS Ground Advantage |
Any title containing “Media Mail” | USPS Media Mail |
International shipping | Maps to… |
Any title containing “Expedited” | UPS Expedited |
Any title containing “Express” | UPS Express |
Any title containing “UPS Standard” | UPS Standard |
Note: The shipping method title in Shopify must match exactly, including capitalization and spacing, for mapping to work correctly.
The rows in the table above reflect our current carrier offering, but the logic will remain the same for any other carriers we decide to add in the future. In other words, as long as the name of the shipping service is correct, and spelling and capitalization are accurate, the Shopify shipping method will map to the carrier correctly.
🧑⚖️ Important rules for shipping method titles in Shopify
- The title of the shipping method must exactly match the value in the table above — including capitalization and spacing.
- ✅ Example: “UPS 2nd Day Air” will map correctly.
- ❌ Example: “UPS 2nd Day air” will not map correctly.
- Additional words before or after the required phrase are OK as long as the required phrase is included.
- ✅ “Free UPS 2nd Day Air Shipping” will map correctly.
If there is no exact match, your shipment will fall back to the default shipping method you have configured. If you have not configured a default shipping method, your shipment will fall back to the lowest cost tracked method available.
