(586) Area Code Business Phone Numbers
The 586 area code covers Macomb County and the northeastern Detroit suburbs, with Warren at the center. It was split off from 810 back in 2001, and it has been the voice of this corner of metro Detroit ever since.

586 showed up in 2001 when 810 ran out of numbers and the state carved off Macomb County and a slice of the eastern suburbs. For anyone who grew up in Warren, Sterling Heights or Saint Clair Shores, 586 on the caller ID still means home.
Warren is the third-largest city in Michigan with roughly 139,000 residents, and it carries a work mix most people do not expect from a suburb [1]. The GM Tech Center and the U.S. Army Detroit Arsenal sit here, and around them more than 4,000 businesses do the day-to-day work of auto suppliers, machine shops, trades, clinics and family restaurants [2].
A 586 number on your business line tells people you are one of them. Customers in Roseville or Eastpointe are far more likely to pick up a local ring than a strange toll-free one, and Tonet lets you put that same number on a desk phone, a laptop and your cell at once.

What You Get With a 586 Number From Tonet
Every feature is included on both plans. You pick the number, we build the phone system in a few seconds, and you can start taking calls the same morning.
Auto Attendant
Greet callers with your own recording, press 1 for sales, 2 for service, and route each key to a person, a group, voicemail or another menu. Perfect for an auto shop or clinic that juggles bays and front desk.
Call Recording
Flip recording on per number for incoming, outgoing or both. Keep the audio for 90 days by default, longer if you need it, and share a single call with a secure link.
AI Transcription
Recorded calls get a searchable transcript with speaker labels, and every voicemail is transcribed and emailed. Short factual summaries sit on each call so you catch next steps without replaying anything.
Business SMS
Send and receive texts from your 586 number, with photos, PDFs and up to ten attachments. One-time A2P 10DLC registration is filed from the dashboard before outbound texting starts.
Mobile App
Same login on iOS and Android as the dashboard, so a tech on a Sterling Heights job or a driver crossing 696 can take the shop line from a phone and nobody misses a call.
Daily Billing
Plans start at $10 per user per month, billed daily against a prepaid balance. Numbers are $2.50 a month, no contract, no seat minimum, cancel any time.
Frequently Asked Questions
Can I get a 586 number if my business is not in Warren?
Yes. You pick the area code in the dashboard, and the number works the same no matter where you are. A shop in Rochester or a remote team outside Michigan can run on a 586 line without any address check.
How much does a 586 number cost?
The number itself is $2.50 per month. Pay As You Go users pay $10 per user per month plus 1 cent a minute and 3 cents a text, and Unlimited is $15 per user per month for US calls and texts under a fair-use policy. A $15 deposit gets you started.
Can I port my existing 586 number to Tonet?
Yes, and it is free. Most ports complete in 7 to 10 business days, sometimes longer depending on your current carrier. Your number keeps working with your old provider until the switch, so there is no downtime.
Will the 586 line ring my cell too?
Yes. The same number can ring your browser, the iOS and Android app and a Yealink desk phone at once, or any subset you choose. A ring group can even ping two or three team members together, with queue hold music if everyone is busy.
Can I set different hours for the Warren office and after-hours routing?
Yes. Each number gets a schedule by day and time, plus a Calendar override for holidays. During open hours the call hits your front desk, after hours it goes to voicemail or a different group, no manual flipping of switches.
