If you're dialing around southern Minnesota, you might have noticed a subtle shift in how you make calls. It's all thanks to a new area code, 924, being layered onto the familiar 507 region. Think of it like adding a new lane to a busy highway – the goal is to keep things moving smoothly by ensuring there are enough phone numbers for everyone.
This process, known as an area code overlay, means that both the 507 and the new 924 codes will cover the same geographic area. This includes cities like Rochester, Mankato, Austin, and Winona, along with countless smaller communities scattered across southern Minnesota. The good news? You won't have to change your existing phone number or your current area code. Your number remains yours, and what's a local call now will still be a local call.
What will change is how you dial. Starting January 30, 2024, the Minnesota Public Utilities Commission made it a requirement to dial the full 10 digits – that's the area code plus the seven-digit number – for all calls. Initially, if you forgot and dialed just seven digits, your call would still go through. However, as of July 30, 2024, this grace period is over. If you don't include the area code, your call simply won't connect, and a recording will gently remind you to try again with the full number.
This change isn't just about making phone calls; it affects any device programmed to dial automatically. We're talking about things like your home security system, your fax machine, speed dial settings, or even your pet's ID tag if it has a programmed number. All of these will need to be updated to include the area code. It's a good idea to take a moment and check your websites, stationery, and any other materials where your phone number is listed to ensure the area code is present.
It's also worth remembering that this overlay doesn't change the price of calls or your service coverage. And, thankfully, the familiar three-digit numbers for emergencies and quick information – 911, 988, 211, 311, 411, 511, 611, 711, and 811 – remain just as easy to reach.
If you're feeling a bit uncertain or have specific questions, AT&T is available at 800.288.2020, or you can visit their website. The Minnesota Public Utilities Commission also has information available at https://mn.puc.state.mn.us.
It's a small adjustment, really, but one that ensures the continued availability of phone numbers for everyone in the 507 region as we move forward.
