The Skanner News - New Area Code Coming to Seattle Area
The Utilities and Transportation Commission today approved a plan to implement a new area code to address the need for additional numbers in the Seattle area. The new area code, 564, will overlay the existing 206 area code. Current phone numbers with the 206 area code will not change. The 564 area code will be assigned to new phone numbers once no more 206 area code numbers are available.
