'''Area codes 507 and 924''' are telephone [[area code|area codes]] in the [[North American Numbering Plan]] for the southern fifth of [[Minnesota]], including cities such as [[Rochester, Minnesota|Rochester]], [[Mankato, Minnesota|Mankato]], [[Worthington, Minnesota|Worthington]], [[Fairmont, Minnesota|Fairmont]], [[Albert Lea, Minnesota|Albert Lea]], [[Northfield, Minnesota|Northfield]], and [[Austin, Minnesota|Austin]]. The original area code, 507, was the third area code created for use in the state in 1954, following the original [[Area code 218|218]] and [[Area code 612|612]]. It was created from the southwestern portion of 218 and the southern portion of 612. It 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 [[Minneapolis-St. Paul|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 Administration|North American Numbering Plan Administrator]] forecasted the exhaust of all available telephone numbers 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.
