Area Code 702 History:
Area code 702 was put into service. In 1998 area code 702 was split to form area code 775.
On June 3, 2014 area code 725 was put into service as an all services overlay of area code 702. Effective May 03, 2014 ten digit dialing in the 702 and 725 area codes became mandatory.
Ten digit dialing (area code + seven digit number) is necessary in the 702/725 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
