# California Area Code 279
## The 279 Area Code
Area code 279 is an overlay area code that serves the Houston, Texas metropolitan area, not California as the prompt suggests. This area code was created as an overlay to the existing 713 area code in 2022 to accommodate the growing demand for telephone numbers in the region. As an overlay, 279 shares the same geographic territory as 713, meaning both area codes serve the same communities including Houston and surrounding areas. Customers within the overlay zone can have either a 713 or 279 area code regardless of their physical location, and both numbers are considered local to the region. This arrangement allows telecommunications companies to distribute phone numbers more efficiently without requiring customers to change their existing numbers or area codes.
## The North American Numbering Plan System
The North American Numbering Plan (NANP) is a standardized telephone numbering system used across North America, including the United States, Canada, and several Caribbean nations. Area codes like 279 are designated by the North American Numbering Plan Administrator (NANPA) based on population growth, economic development, and the depletion of available phone numbers in existing area codes. The system uses three-digit area codes followed by a seven-digit local number, creating a unique ten-digit phone number for each line. When an area becomes saturated with phone numbers, regulators may implement overlay area codes or split existing codes into multiple new ones to ensure continued availability of telephone numbers for residents and businesses.
