The 720 area code was created in the early 2000s as a split from the original 303 area code that once covered all of Denver. Today, 720 is exclusively tied to Denver County, located in the heart of Colorado. It covers iconic neighborhoods like:
Denver – the bustling heart of the city
Aurora – a diverse suburban community
Lakewood – known for its parks and recreation
Boulder – a vibrant college town with a thriving cultural scene
Littleton – offering a blend of small-town charm and urban conveniences.
For generations, 720 has represented Colorado pride, offering the best of urban life with fast access to all local attractions.
The 720 area code operates in the Mountain Time Zone (MT)–the same time zone as Denver. 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 720 number means you’re aligned with Mountain Standard Time (MST) in winter and Mountain Daylight Time (MDT) in summer.
The 720 area code covers all of Denver County, including:
Denver
Aurora
Lakewood
Boulder
Littleton
and many more.
Getting a 720 number gives your calls a familiar, local presence in one of Colorado’s busiest urban regions. It’s perfect for real estate agents, freelancers, remote workers, and anyone who wants to appear local while staying flexible.
