In this comprehensive guide, we'll delve into the specifics of La Jolla's area code, providing you with the dialing information you need to stay connected.
Understanding Area Codes: A Brief Overview
Area codes are three-digit numbers that precede a telephone number, identifying a specific geographic region within the United States. These codes are used to route calls to the correct destination, ensuring seamless communication across the country. The North American Numbering Plan Administration (NANPA) is responsible for managing area codes, assigning new codes as needed to accommodate growing populations and increasing demand for telephone services.
La Jolla’s Area Code: 858 and 619
La Jolla is served by two area codes: 858 and 619. The 858 area code is the primary code for the region, while the 619 area code is an overlay code, which means it serves the same geographic area as the 858 code. This dual-code system allows for a greater number of available phone numbers, supporting the growth and development of the La Jolla community.
| Area Code | Introduced | County |
|---|---|---|
| 858 | 1989 | San Diego |
| 619 | 1947 (overlay in 2017) | San Diego |
It's essential to note that the 858 area code was introduced in 1989, while the 619 area code has been in use since 1947. The 619 code was initially assigned to the entire San Diego area but has since been overlaid with the 858 code to provide additional phone number capacity.
