History of 408 Area Code

The 408 area code was created in 1959 as a split from the 415 area code, which originally covered most of northern California. The split was necessary to accommodate the growing population and demand for phone numbers in the region.

In 1998, the 408 area code was split again to create the 831 area code, which covers the coastal areas of Monterey County, San Benito County, and Santa Cruz County. The split was motivated by the rapid growth of the telecommunications industry and the need for more prefixes and numbers.

In 2012, the 408 area code was overlaid with the new 669 area code, which means that both area codes serve the same geographic area and customers have to dial 10 digits for local calls. The overlay was implemented to avoid exhausting the available numbers in the 408 area code and to provide more options for customers.

The 408 area code is home to many high-tech companies and institutions, such as Apple, Google, eBay, Cisco, Adobe, Stanford University, and San Jose State University. It is also known for its cultural diversity and attractions, such as the Winchester Mystery House, Santana Row, Happy Hollow Park and Zoo, and Levi’s Stadium.
