The 312 area code was created in 1951 as a split from the original 212 that once covered all of Chicago. Today, 312 is exclusively tied to Chicago, located at the heart of the city. It covers iconic neighborhoods like:
Chicago – the bustling heart of the city
Cicero – a vibrant suburb neighboring Chicago
Berwyn – known for its rich culture and history
For generations, 312 has represented Chicago pride, offering the best of city life with fast access to all regions.
The 312 area code operates in the Central Time Zone (CT)–the same time zone as Chicago. 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 312 number means you’re aligned with Central Standard Time (CST) in winter and Central Daylight Time (CDT) in summer.
The 312 area code covers all of Chicago, including:
Chicago
Cicero
Berwyn
and many more.
Getting a 312 number gives your calls a familiar, local presence in one of Chicago’s busiest urban regions. It’s perfect for real estate agents, freelancers, remote workers, and anyone who wants to appear local while staying flexible.
