Few area codes are as tied to a city's identity as 313 is to Detroit. It has been the local prefix since 1947, and it shows up constantly in Motown lyrics, techno records, and the 2002 film 8 Mile as shorthand for the city itself[1]. When your number starts with 313, people from the area know exactly where you are.
The Detroit business scene right now is a mix of steady grind and fresh energy. Michigan Central Station, the rebuilt train depot in Corktown, has grown into a 30-acre tech and culture hub that has already pulled more than 2,000 workers into the neighborhood[2]. At the same time, local owners are still watching costs closely, with Detroit-area consumer prices up about 2% over the past year[3].
In that kind of market, a local number matters. A 313 line tells a customer in Dearborn or Redford that you are actually here, not routing through a call center three states away. Tonet lets you pick one up, port an existing one, or add a second line without swapping out your cell phone.
Cities Served by the 313 Area Code
The 313 covers Detroit and a tight ring of inner Wayne County suburbs. If your customers live or work in any of these communities, a 313 number reads as a neighbor.

Frequently Asked Questions
Can I get a 313 number if I am not in Detroit yet?
Yes. There is no residency requirement. If you plan to serve Detroit-area customers or want a local presence in the market, a 313 number is available to you.
How long does it take to activate a new 313 line?
Usually a few minutes. Sign up, pick your 313 number from the available list, and you can start making and taking calls right away.
Can I keep my current 313 number if I switch to Tonet?
Yes. Porting is free. Bring your existing 313 number over from your current carrier and keep every contact you already have.
Is 313 the only area code in Detroit?
Yes. Unlike most major metros, Detroit never got an overlay, so 313 covers the city and its inner Wayne County suburbs on its own. That makes it fairly recognizable and worth holding onto.
How much does a 313 business number cost?
Plans start at $10 per user per month billed daily, with no contracts. Additional numbers are $2.50 per month each, so you can add a second line for a side of the business without much thought.
