News Summary
Detroit is set to introduce a new area code, 679, as an overlay to the existing 313 area code. This change is necessary due to the anticipated depletion of available numbers in the 313 area code by 2025. The mandatory 10-digit dialing will begin on April 7, 2025, along with a permissive period for six months. Local calls will require the full area code plus the phone number, encouraging residents and businesses alike to update their dialing practices. A public hearing is scheduled for March 9, 2023, to discuss this transition.
Detroit’s Got a New Code Coming: Area Code 679 Joins the Party!
Hey there, Detroit! There’s some pretty big news buzzing around the city, and it involves our beloved 313 area code. As it turns out, this iconic number is expected to run out of available phone numbers by the third quarter of 2025. But don’t worry, we’re not losing our cherished code—oh no! Instead, we’re welcoming a new code into the family: say hello to area code 679.
What’s the 411 on the New Area Code?
For those of you who are as curious as a cat, here’s the scoop: the 679 area code will be introduced as an “overlay” for the Detroit area. This means that when you sign up for a new phone number, you could be assigned either a 313 or a 679 area code, giving you more options for your digits. But for all you existing customers rocking the 313, no need to fret! Your numbers will stay just as they are.
What Changes with Dialing?
Now, as we all know, change can bring about some hiccups. Starting on April 7, 2025, we’re shifting to a mandatory 10-digit dialing pattern (that’s area code plus phone number) for local calls. If you’re still in the habit of pressing just seven digits, there’s going to be a little practice period to help you along. For the first six months, a Permissive Dialing Period will kick in. That means you’ll still be able to dial just seven digits, but everyone is *strongly encouraged* to start dialing 10 digits. After this grace period, the 10-digit dialing will be mandatory, kicking in on October 7, 2025. Mark your calendars!
But Wait, There’s More! Important Updates Ahead!
Heads up, everyone! If you’ve got any automated dialing systems, like life safety alarms or medical devices, you’ll need to update them to fit the new dialing format. And it wouldn’t hurt to give your advertisements, personal ID tags, and websites a little refresh to keep up with the times. Failing to dial the full ten digits might lead to a friendly reminder from the phone system—talk about a gentle nudge!
The Heart and Soul of 313
Let’s not forget the cultural significance of the 313 area code. It’s been around since 1947 and has become a symbol of Detroit’s identity and pride. It’s woven into the fabric of our city, representing everything from our rich history to our strong community spirit.
What Comes Next?
There’s a public hearing scheduled for March 9, 2023, at the Wayne County Community College District to discuss this new area code. The 679 area code is specifically designated to serve Detroit, Hamtramck, Highland Park, and a handful of our beloved suburbs. This change was approved by the Michigan Public Service Commission (MPSC) and is guided by the North American Numbering Plan Administration (NANPA).
Time for Transition
Over the years, there have been previous attempts to introduce 679, but they were delayed. Interestingly enough, the need for an overlay was identified more than 20 years ago! So, it seems like the moment has finally arrived. Let’s embrace this change together! Local organizations are aware of the implications this change may have, especially for small business owners, but they’re standing strong and committed to supporting each other, no matter the area code.
Stay tuned for more updates and remember to spread the word! Soon, you’ll find yourself dialing 10 digits just like a pro!
