The 924 area code is the latest addition to Minnesota’s telecommunications landscape, serving as an overlay to the existing 507 area code. This new area code was implemented to meet the increasing demand for phone numbers in the southern part of the state.
The 507 area code, which had been serving the region since 1954, was projected to exhaust its available prefixes by the end of 2025. To ensure a continued supply of phone numbers for residents and businesses, the Minnesota Public Utilities Commission (PUC) approved the implementation of the 924 area code as an overlay.

What is an Overlay Area Code?
An overlay area code, like the 924 area code, shares the same geographic region as an existing area code. This means that both the 507 and 924 area codes will be assigned to phone numbers within the same region. This approach allows for more efficient use of available phone numbers and avoids the need for disruptive area code splits, which can cause confusion and inconvenience for residents and businesses.
Geographic Coverage
The 924 area code covers the same geographic area as the 507 area code, which includes cities such as Rochester, Mankato, Austin, Winona, and Worthington, as well as many smaller communities in southern Minnesota.
10-Digit Dialing
With the introduction of the 924 area code, 10-digit dialing became mandatory for all calls within the region, including local calls. This means that callers must dial the area code followed by the seven-digit phone number, even for calls within the same area code.
Timeline and Transition
The implementation of the 924 area code has been a phased approach. As of July 21, 2023, residents and businesses are encouraged to begin dialing 10 digits for all calls. However, during a grace period, calls dialed with only seven digits will still go through. As of January 30, 2024, 10-digit dialing is mandatory for all calls. Starting August 30, 2024, new telephone lines or services may be assigned numbers with the 924 area code.
Impact on the Region
The 924 area code is more than just a new set of numbers; it is a testament to the ongoing growth and development of southern Minnesota. It signifies a thriving economy, a diverse community, and a commitment to staying connected in an increasingly digital world.
While the transition to 10-digit dialing may require some adjustment, the 924 area code is essential for ensuring that everyone in southern Minnesota has access to reliable and efficient phone services. This is crucial for economic development, as businesses can easily establish a local presence and connect with customers in the region.
The Future of 924
The 924 area code is expected to meet the region’s communication needs for the foreseeable future. As southern Minnesota continues to grow and develop, the 924 area code will play an increasingly important role in connecting people and businesses, fostering economic activity and community engagement. The 924 area code is not just a number; it’s a symbol of progress and connectivity in southern Minnesota.
