Why choose a 720 virtual phone number?
Look local to Denver buyers
If you're selling something online to people in Denver, a 720 number signals you're nearby. Buyers are more likely to respond when the number matches their area.
Dating in the metro
A 720 number fits right in on dating apps for anyone browsing matches in Denver, Aurora, or Lakewood. It reads as someone who's actually local, not out of state.
Job hunting across the region
Employers in Denver, Colorado Springs, or Fort Collins tend to notice a local area code on a resume or application. It's a small signal that you're already in the area or planning to be.
Moving to Colorado
If you're relocating to Thornton, Arvada, or Westminster, a 720 number lets you start using a local-sounding line before you've even packed the truck.
Keep the number after you leave
People who move away from Denver but still have friends, family, or business ties there can keep a 720 number active on a second line instead of losing it.
Separate work from personal life
Give out a 720 number for work or side projects while keeping your personal cell number private, even if you live right in the Denver metro.

The 720 area code covers Denver and the wider Front Range corridor, including Colorado Springs, Aurora, Fort Collins, Lakewood, Thornton, Arvada, and Westminster. It's one of the main area codes tied to Colorado's largest metro region.
720 is an overlay code that shares the same geographic area as 303. Both codes are dialed in Denver and the surrounding suburbs, so a 720 number fits in naturally alongside older 303 numbers already common in the region.
The region sits in the America/Denver timezone, which follows Mountain Time. If you're calling or texting contacts across Colorado Springs, Fort Collins, or Denver itself, everyone's on the same clock, so there's no timezone math to worry about.

Why do business in Denver?
Denver anchors a large, diverse Colorado economy that stretches through Aurora, Colorado Springs, and the northern suburbs. A 720 number fits naturally into a metro built on healthcare, technology, and logistics work.
Healthcare
Denver and its suburbs host major hospital systems and clinics that draw patients and staff from across the Front Range, making healthcare one of the metro's steadiest employers.
Technology
Denver has a growing base of tech companies and startups, with workers commuting in from Aurora, Lakewood, and Arvada to fill software and IT roles.
Logistics
Denver's position along major highway and rail routes makes it a natural hub for shipping and distribution serving Colorado and neighboring states.
