The 840 area code was created in 1951 as a split from the original 212 that once covered all of San Diego County. Today, 840 is exclusively tied to San Diego County, located in California. It covers iconic neighborhoods like:
Chula Vista – the bustling heart of the region
Oceanside – the vibrant, coastal city
Carlsbad – home to beautiful beaches and family attractions
Escondido – known for its rich culture and history
Vista – a city with a charming vibe and great community spirit.
For generations, 840 has represented San Diego pride, offering the best of coastal life with fast access to all areas.
The 840 area code operates in the Pacific Time Zone (PT)–the same time zone as San Diego County. 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 an 840 number means you’re aligned with Pacific Standard Time (PST) in winter and Pacific Daylight Time (PDT) in summer.
The 840 area code covers all of San Diego County, including:
Chula Vista
Oceanside
Carlsbad
Escondido
Vista
and many more.
Getting an 840 number gives your calls a familiar, local presence in one of San Diego’s busiest urban regions. It’s perfect for real estate agents, freelancers, remote workers, and anyone who wants to appear local while staying flexible.
