Starting October 20, all phone calls made within the 408 area code must include 11 digits – 1+area code+telephone number – even if the call is from one 408 number to another 408 number. The change results from the addition of a second area code, 669, to the region as an overlay to accommodate the demand for new phone numbers. Current 408 numbers will not change to a 669 area code.
Starting now you can convert the pre-programmed phone numbers on your cell phones, fax machines, Internet dial-up numbers, voice mail services, alarm and security systems, etc. to dial all 11 digits. After October 20, calls made without the 1+area code+telephone number will not be completed and a recording will instruct you to hang up and dial again.
The 669 area code will serve customers in the same geographic region as the current 408 area code that covers most of Santa Clara County and small portions of Alameda and Santa Cruz Counties. It is expected that new telephone services that start in November 2012 or later will most likely receive the new 669 area code. The price of a call, coverage area, or other rates and services will not change due to the overlay. What is a local call now will remain a local call regardless of the number of digits dialed.
You can still dial just three digits to reach 9-1-1 for emergencies, as well as 2-1-1 for United Way’s Information & Referral helpline, 4-1-1 for directory assistance or 5-1-1 for public transportation information.
