DECISION GRANTING RELIEF OF THE 408 NUMBERING
PLAN AREA IN THE FORM OF AN ALL-SERVICES OVERLAY

1. Summary

By this decision, we adopt an all-services overlay (overlay) to resolve the forecasted exhaust in the 408 numbering plan area,¹ including a 13-month implementation schedule. The overlay will provide additional numbering resources to meet the demand for telephone numbers. Implementation shall commence immediately. To facilitate implementation of the overlay, we also adopted a public education program.

No customers will be required to change their area code or specific telephone number. New telephone numbers with the 669 area code may be issued to customers beginning one month after the start of the mandatory dialing period. This proceeding is closed.

¹ Also known as an "area code", this number normally represents a geographic area within a state. In the current case, the numbering plan area is 408. Throughout this decision, numbering plan area and area code will be used interchangeably.
