Why businesses choose 312
Chicago's central business code. A 312 number tells customers in Downtown Chicago that you are part of their market, and it matches a company address or registration in Illinois.
You do not need an office or a SIM card there. Your 312 line lives in the cloud: answer calls in the browser, forward them to any phone in the world, and read and reply to texts from your dashboard.
What you get with a 312 number
- Inbound and outbound calls, in the browser or forwarded to your mobile
- Two-way SMS in a shared inbox, with browser and email alerts
- Optional voicemail, online fax, caller ID name and E911
- Monthly billing, no contract: cancel from the dashboard at any time
