When there's a risk of an area code running out of phone numbers, an 'Overlay Area Code' is created that has the same geographic boundaries as the existing area code. In this case, the 204 code has been Overlayed with one of the following codes: 431 or 584. New phone numbers in the Riverdale area will be assigned with one of these codes: 204, 431 or 584. As a result, placing a call in the Riverdale area will require 10-digit dialing (where you enter both the area code and then the phone number).
