1.  Navigate to **All** > **Field Service** > **Administration** > **Service Location Parent Configuration**.

2.  On the Parent Determination Configuration page, click **New**.

3.  Choose the determining factor for the rule to use and provide the value.

    |Criterion|Rule action|
    |---------|-----------|
    |**Zip/Postal code**|Assigns the provided zip or postal code to a parent location.|
    |**Min Zip/Postal codeMax Zip/Postal Code.

    |**CityState.

**|Assigns the city and state to a parent location.|
    |**State**|Assigns the state to a parent location.|

    The **Country** and **Parent** fields are required.

4.  Enter the **Country** name in the text field.

5.  In the **Parent** field, click the Lookup using list icon \( \[Omitted image "magnifying-glass.png"\] Alt text: Lookup icon.\) and select the parent location from the region list.
