# How to change the Main Line number in Dialpad

## Problem

You've added a new number in Dialpad, but it became the primary number. You want to make the primary number the old number.

## Solution

The last number you add as an office number in ServiceTitan becomes the *Primary Number* under the *Main Line* numbers in DialPad. You can't make the change in Dialpad, but you can in ServiceTitan.

1. Go to ServiceTitan and click on **Settings > Phones Pro > Phone Numbers**.
2. Locate the number you want to be the *Primary Number*.
3. Hover over the number and click on the **Edit** icon.
4. Locate the **Assign Number to Target** drop down menu.
5. Open the drop down menu and select the **Office** name. Then click **Save**. This makes the number the *Primary* one under the *Main line*.
6. To verify, go to DialPad and click on **Settings > Main line**. You will see the updated primary number.

**To add a non-primary number in Dialpad:**

1. Add a new number in ServiceTitan software by navigating to **Settings > Phones Pro > Phone Numbers** add the number to the **Reserve Pool**.
2. Go to your **Admin Settings** in [DialPad](https://www.dialpad.com/).
3. Go to **Main Line** and manually add the number by clicking **Add Number**.
