10-Digit Dialing Changes

Posted: 7/27/2017 7:33:00 AM

10-digit dialing goes into effect Saturday, July 29th. 


The new dialing procedure requires callers in the western Washington area codes (206, 253, 360, 425, and 564) to dial the area code plus the 7- digit telephone number, for example, 253-XXX-XXXX. Local calls will continue to be local, even though 10-digit dialing will be required.


Preprogrammed phones, especially safety and security equipment, such as medical alert devices, and alarm and security systems must be programmed to use 10-digit dialing.
