The 858 area code was created in 1999 as a split from the original 619 area code that once covered all of San Diego County. Today, 858 is exclusively tied to San Diego County, including iconic cities like:
San Diego – the bustling heart of the county
Chula Vista – a vibrant city near the coast
La Mesa – known for its charming downtown area
El Cajon – rich with cultural diversity
Santee – a growing community with scenic views
For generations, 858 has represented San Diego pride, offering the best of coastal living with fast access to urban amenities.
The 858 area code operates in the Pacific Time Zone (PT)–the same time zone as San Diego. This is important for businesses and professionals who need to stay in sync with local clients, suppliers, and partners. Whether you’re scheduling calls, running local ads, or managing customer support, having a 858 number means you’re aligned with Pacific Standard Time (PST) in winter and Pacific Daylight Time (PDT) in summer.
The 858 area code covers all of San Diego County, including:
San Diego
Chula Vista
La Mesa
El Cajon
Santee
and many more.
