Campus Resident Service
Local Telephone Service

Local service (dial tone) is included as part of your campus residence service. There is no charge for placing local calls in the Denver metro area.

Local Calls Require 10 digits

The greater Denver metro area is covered by area codes 303 and 720. Because there are two codes assigned to one geographic area, you must dial 10-digits, including the area code, for all local calls. For further information on dialing local calls see the Dialing Instructions section of this site.
