Area code 507
Area code 507 is the telephone numbering plan code for the southern fifth of Minnesota, including cities such as Rochester, Mankato, Worthington, Fairmont, Albert Lea, and Austin. It was the third area code created for use in the state in 1954, following the original 218 and 612. It was created from the southwestern portion of 218 and the southern portion of 612.
In the original 1947 plan, area codes with a middle digit of "0" (zero) were assigned only to states that were entirely covered by a single area code. Area code 507, along with area code 606 in Kentucky and area code 607 in New York, were the first area codes with a middle digit of "0" to be assigned in states that had more than one area code.
The region directly bordered 612 (to the south) until that area code was divided up in the 1990s. The western half of 507 bordered area code 320 starting in 1996, and then later came to border area code 651 (1998) and area code 952 (2000). The northern border of 507 was modified slightly so that growing communities in and near the Twin Cities would be more closely linked with that region by telephone. 612 has now shrunk down to include just Minneapolis and a few surrounding suburbs, and no longer borders 507.
