# Tracking by phone number or email address
Tracktor supports looking up orders by phone number as well as email address if your Shopify store is configured to allow checkout with email or phone number.
To make this experience clear to your users, you will need to make a couple of changes to the **Translation Strings** under the **Tracking Page** section. Follow the steps below to get started.
In order for users to look up their order by phone number, they must have checked out using their phone number, not their email address. If they check out with their email address, they must use their email address to look up their order.
1. **Configure your Shopify Store to allow checkouts via Phone or Email**
Go to your Shopify admin dashboard, click on **Settings**, then on **Checkout**. In the **Customer contact method** section, check the first option, "Phone number or email".
2. **Set your Tracktor Translation strings**
From the Tracktor dashboard, click on the **Settings** tab, then scroll down to the **Customize Language** section.
Edit the **email** and **incorrect\_email** strings to mention the phone number as well.
3. **Don't forget to click the blue Save Changes button in the top right.**
