A 312 phone number in Chicago
Hand out a Chicago area code without handing out your own number. Calls ring your phone, texts land in a web inbox, and one tap burns the number.
- $1 for a 7-day trial. When the 7 days end, your card is charged $9.99 for the first month, and the plan renews at $9.99 every month until you cancel.
- If the trial's allowance runs out first, use pauses and nothing more is charged until the 7 days end or you start the plan yourself.
- Extra minutes, numbers and burns go on the same monthly bill.
- Cancel any time with our ready-made cancel email. No reason needed. The plan runs to the end of the paid month, then your numbers are burned into a 30-day quarantine.
- Your first paid month can be refunded within 7 days of paying it. Write to hello@numberburn.com to ask.
Receive-only: calls ring your mobile, texts land in a web inbox.

Who asks for 312
Renting a loft near the Loop
A property owner advertising a downtown loft wants prospective tenants to ring a number that is easy to shut off later. A line for the listing alone avoids unknown callers showing up on the owner’s main phone.
Staffing a trade show at McCormick Place
A sales rep flying in for a convention hands out a contact line to buyers walking the floor. Calls after the event are routed into one place rather than scattered across text threads.
Selling bikes before winter
A cyclist in Oak Park posts a road bike and a commuter frame for sale. A throwaway number lets buyers arrange a meetup near the lake without learning the seller’s real one.
Chicago and the area around it
Chicago hugs the southwestern shore of Lake Michigan, with the river threading through the Loop and the lakefront parks running north and south. Evanston and Skokie are the first towns past the city line toward the north. Oak Park and Cicero press against the western boundary of the city.
Evanston, Skokie and Oak Park residents hearing a ring from 312 tend to place it in downtown Chicago.

Questions
What does it take to start with a 312 number?
Start a trial, choose 312 as the area code and name the number. NumberBurn looks for a number in that code when you check out, so which ones are free is confirmed there, not on this page.
Does a 312 number suit a business?
It can. A 312 number gives a Chicago look to a work line, a listing or a client contact, and calls ring the phone you already carry. It cannot place calls or send texts, so it is for being reached, not for outreach.
Does 312 read as local to callers outside Chicago?
Near Chicago it will. Farther away, callers see an Illinois code and still know it is a local-format number; pick the code of the place your callers are in if that matters to you.
Can I call or text from a 312 number?
No. NumberBurn numbers are receive-only: calls ring your own phone, texts appear in a web inbox, and the number cannot dial out, send texts or reach 911.
What does the trial include for a 312 number?
The 7-day trial costs $1 at signup and holds 1 number and 100 forwarded minutes. A card is collected at checkout. When the trial ends, your card is charged for the first month and the plan renews every month until you cancel, from $9.99 a month.
