Covers: Chicago (Downtown Loop and immediate core) · Get a Chicago number
Few numbers say downtown Chicago as clearly as 312.
The code has served the city's core since 1947, and today it covers the Loop and the blocks immediately around it. It is the prefix of trading floors on LaSalle Street, law firms and headquarters towers along the river. For clients across the city, a 312 caller ID signals an established downtown business. That impression is hard to get any other way without paying for the office.
Office space in the Loop is expensive. A 312 number is not.
A virtual 312 line lets a remote or suburban team present itself as part of Chicago's business district. You can reach clients in River North, the West Loop and beyond while your people work from anywhere. 312 and 872 cover the same area, so both read as downtown, and new numbers are often issued on 872. Calls ring on the desktop and mobile apps, so nobody is tied to a desk phone.
Downtown clients do not wait long, so neither should your phone line.
