The History of Area Code 408

Established in 1947 as one of California’s original three area codes (along with 213 and 415), 408 initially covered a vast area stretching from the Pacific Coast to the Central Valley. As the population grew, the area code was split several times. In 1959, area code 408 was retained for the southern portion of the region, while the northern part became area code 415. Later, in 1998, the southern portion was further divided, creating area code 831. Despite these changes, area code 408 remains a key identifier for Silicon Valley.

The Need for Overlays

Due to the rapid growth of Silicon Valley and the increasing demand for phone numbers, area code overlays have been introduced. An overlay adds a new area code to the same geographic region, requiring 10-digit dialing (area code + seven-digit number) for all calls. Area code 669 is an overlay for the 408 region, ensuring sufficient phone numbers are available for the area's continued expansion.

Identifying the location of a phone number with area code 408 is straightforward. You can use online tools and directories specifically designed for this purpose. These tools allow you to enter the area code and the seven-digit phone number to determine the general geographic location.

Understanding 10-Digit Dialing

In areas with overlays, like the 408 region, 10-digit dialing is mandatory. This means you must dial the area code followed by the seven-digit phone number for every call, even for local calls. This ensures that the call is routed correctly within the overlay area.
