Area Code 507

Area Code 507 History:

01/01/1954
Area code 507 was officially put into service. Area code 507 was created from a split of area code 612.

The Minnesota Public Utilities Commission on March 30, 2023 approved area code 924 as an all services overlay of area code 507 with an implementation date of 08/30/2024. Area code 924 will only become available to subscribers when all assignable central office codes in area code 507 are assigned. Ten digit dialing (area code + seven digit number) will be necessary in the 507/924 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
