{{Short description|Telephone area code for southern Minnesota}} {{Use American English|date=February 2026}} thumb|right|350px|A map of Minnesota area codes. 507 and 924 are in dark brown. '''Area codes 507 and 924''' are telephone area codes in the North American Numbering Plan (NANP) for the southern fifth of Minnesota, including cities such as Rochester, Mankato, Worthington, Fairmont, Albert Lea, Northfield, and Austin. Area code 507 was the third area code created in the state in 1954, following area codes 218 and 612 in 1947. It was created from the southwestern portion of 218 and the southern portion of 612. The numbering plan area (NPA) was overlaid with area code 924 in 2024. It is the first area code overlay complex in Minnesota.
The region was directly bordered by 612 (to the north) until that area code was divided in the 1990s. The western half of 507 bordered area code 320 starting in 1996, and then later came to border also area code 651 (1998) and area code 952 (2000). The northern border of 507 was modified slightly so that expanding 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.
In August 2022, the North American Numbering Plan Administrator forecasted the exhaust of central office code in 507 by 2025.<ref>{{Cite web |last=Tribune |first=Mike Hughlett Star |title=New area code planned for southern Minnesota |url=https://www.startribune.com/new-area-code-planned-for-southern-minnesota/600200734/ |access-date=2023-04-18 |website=Star Tribune|date=24 August 2022 }}</ref> Area code 924 was approved as an all-service overlay to area code 507 by the Minnesota Public Utilities Commission on March 30, 2023.<ref>{{Cite web |last=Tribune |first=Mike Hughlett Star |title=There's a new area code in southern Minnesota's 507 region |url=https://www.startribune.com/theres-a-new-area-code-in-southern-minnesotas-507-region/600268094/ |access-date=2023-04-18 |website=Star Tribune|date=18 April 2023 }}</ref><ref>{{Cite web |date=2023-04-18 |title=This is Minnesota's newest area code |url=https://www.fox9.com/news/this-is-minnesotas-newest-area-code |access-date=2023-04-18 |website=FOX 9 |language=en-US}}</ref> Ten-digit dialing is required as of July 2024.
