A new area code was approved by the Texas Public Utility Commission on February 20, 2020 to be added to the existing 214/469/972 overlay complex, used by residents of Dallas and its Greater Metropolitan Area, and also other surrounding towns like Mesquite, Plano or Richardson.
Since more than one area code and therefore 10 digit dialing are already in use within this Numbering Plan Area there will be no changes in the way telephone calls are dialed when the new 945 area code enters service.
- April 15, 2020 – network preparation and customer education period begins
- January 15, 2021 – new area code 945 enters service
