415 Area Code Overlay Public Education Materials


Telephone companies that provide local service in the 415 Area code region sent the following notifications to their customers to inform them of the overlay.

First set of notifications were sent early July 2014 to inform customers about the upcoming changes. 

Second set of notifications will be sent at the start of 2015 to remind customers of the impending overlay and mandatory new dialing procedure.

Customers are also notified through media announcements.
