No Office Needed
Looking to grow your business in Chicago and build stronger customer connections? A 773 area code number helps you build local trust and boost answer rates — without having a physical office in Illinois.
DialLink makes it easy for SMBs and startups to get a local number with powerful features like AI voice agents, call handling automation, and an intuitive setup. The 773 area code is an overlay for the original 312 area code, and both now serve the same central Chicago area, including The Loop and many surrounding neighborhoods.
Why Choose a 773 Area Code?
The 773 area code covers central and northwestern portions of Chicago, including many neighborhoods just outside The Loop. It was introduced as an overlay to the 312 area code to expand number availability in the area. This means both area codes serve the same region and are equally recognizable to local residents and businesses.
Whether you’re a local entrepreneur, a growing startup, or a national company targeting the Chicago market, a 773 number positions you as local and trustworthy.
From finance and logistics to tech and media, Chicago is a high-value market full of opportunity. A 773 number gives your business a credible presence in the Windy City.
