Beginning November 14th, the new dialing procedure requires that when making a local call in Connecticut you dial the area code plus the 7 digit local number (for example: 860-455-5555). If you do not use the new dialing procedure your call will not be completed and you will receive a recording instructing you to hang up and dial again.
Cellphone calls are no exception. Calls outside the local calling area will still need a 1 before the area code, while local calls will require 10-digit dialing, without the 1.
