# Setting Up Carrier Mapping
### **Overview**
Shopify only supports around 55 carriers. Tracktor supports more than 1000! Tracktor's carrier mapping feature allows you to support carriers that are not supported by Shopify. This happens by overriding Shopify-supported carriers with carriers that Tracktor supports.
Setting up carrier mapping keeps everything in sync — your Tracktor tracking page, your Shopify admin, and your customers' delivery notification emails.

**Tip:** Carrier mapping is also what syncs tracking updates back to Shopify. Once a carrier is mapped, Tracktor sends updates via webhook, which triggers Shopify's out for delivery and delivered email notifications.
{% endhint %}

#### **Setting up carrier mapping**
Head to your Tracktor dashboard and click **Tracking Page** in the left sidebar. Scroll down until you see the **Carrier Mapping** section.
From there, you'll set up two things:
**Shopify Carrier** is the carrier you picked when you fulfilled the order in Shopify. If your carrier isn't in Shopify's list, this will be **Other**.
**Actual Carrier** is the carrier you actually shipped with. This is who Tracktor will ask for tracking info.
Once you've set both, click **Save**. Any order fulfilled with that carrier going forward will start showing tracking.
***
### **Not sure what carrier name Shopify is using?**
Go to your Shopify admin, open an order, and check the fulfillment details. Whatever carrier name is listed there is what you'll enter as the **Shopify Carrier** in the mapping.
If the name looks off, like "USPS Ground Shipment" instead of just "USPS," that's okay. You can type it in manually and map it to the correct actual carrier. Tracktor will recognize it from there.
***
### **Using dropshipping?**
The fastest way to get set up is to click **Add Popular Carriers** in the Carrier Mapping section. This automatically adds the most common carriers used by dropshippers, so you don't have to build the list yourself.
If your carrier still isn't showing up after that, you can add it manually. Set **Shopify Carrier** to *Other* and select your carrier under **Actual Carrier**.
***
#### **Testing your mapping**
Once your mapping is saved, open an order in your Shopify admin, click **More Actions**, and select **Tracktor: Track Order**. You can also check from the **Reports** tab in your Tracktor dashboard.
If tracking still isn't showing up after that, [reach out to our support team](mailto:contact@theshoppad.com) and we'll help you figure out what's going on.

### **My fulfillment service is using a carrier name Tracktor doesn't recognize**
Sometimes a fulfillment service will fulfill orders using a carrier name that doesn't match exactly what Shopify or Tracktor expects. This is more common than you'd think and easy to fix with carrier mapping.
For example, your fulfillment service might label a shipment as "USPS Ground Shipment" when the correct carrier name is just "USPS." Tracktor won't find tracking for "USPS Ground Shipment" because it doesn't recognize that exact name.
To fix it, set up a mapping with "USPS Ground Shipment" as the **Shopify Carrier** and "USPS" as the **Actual Carrier**. Type the unrecognized name into the Shopify Carrier field and select the "Create option" result that appears. From that point on, any order fulfilled with that name will track correctly.
