The Minnesota Public Utilities Commission has approved the addition of a new area code of 924 to the geographic region of the 507 area code. This process is known as an area code overlay.
An overlay does not require customers to change their existing area code, but it will require using a new dialing procedure to complete calls. Anyone with a 507 area code will need to start dialing 507 prior to the seven-digit phone number. The new area code dialing procedure will go into effect as of Jan. 30, 2024.
Callers will be granted a grace period in case they forget to dial the area code until July 30. As of July 30, one MUST dial the area code plus seven-digit telephone number on all calls, including calls with your same area code. If you don’t dial the area code first, your call will not be completed, and a recording will instruct you to hang up and dial again including the area code.
Beginning Aug. 30, new telephone lines or services may be assigned numbers with the new 924 area code. For more information, call the number on your phone bill or access the Minnesota Public Utilities Commission website.
