924 Kode Area: Koridor Mayo Clinic Minnesota

Rochester, Mankato, and Worthington share the 924 area code, an overlay covering the same southern Minnesota footprint as 507. Numbers began carrying 924 on August 30, 2024, following approval from the Minnesota Public Utilities Commission in March 2023 — making it the state's very first overlay and its first new area code since 2000.

This guide covers 924's counties and cities, what's driving demand in a region anchored by world-class healthcare, how calls work across such a spread-out rural footprint, which features are worth adding to a 924 line, and how to get a number of your own.

Counties and cities at a glance

What's driving demand across southern Minnesota

Southern Minnesota's economy is anchored by one of the world's best-known medical centers, plus agriculture and manufacturing:

Mayo Clinic Rochester's Mayo Clinic draws patients, staff, and researchers from around the world, driving heavy phone-line demand well beyond what the local population alone would need.

Agriculture Worthington, Fairmont, and the surrounding farmland anchor a large agricultural processing and cooperative sector.

Manufacturing Mankato and the region's smaller cities host a steady manufacturing base that keeps adding commercial lines.

Many of these southern Minnesota businesses are moving their phone systems onto UCaaS (Unified Communications as a Service) — one cloud platform for calling, video, and messaging that scales as a company adds locations across a spread-out region, the same pattern behind newer overlays like 920 in Wisconsin's Fox Valley.

Calls and texts across a rural, spread-out footprint

A call from Rochester to Worthington covers well over 150 miles, yet it's still a standard local 924/507 call — the same rates and ten-digit dialing rules apply across the entire southern Minnesota region, whether it's a Mayo Clinic patient calling home or a farm cooperative coordinating with a supplier across the state.

Features worth adding on a 924 number

A hosted 924 or 507 line pairs well with call routing across multiple clinic, farm-office, or shop-floor extensions, an auto-attendant for after-hours patient or customer calls, and call analytics for tracking response times. Most providers bundle these into a flat monthly plan rather than pricing each feature separately.

How to get a 924 area code number

Sign up with a VoIP provider such as My Country Mobile, search available numbers in either 924 or 507, and pick a prefix tied to the part of southern Minnesota your business serves. Most providers can port an existing number over from another carrier, activate a new line same-day, and route calls to any device without new hardware.

Time zone & how to dial a 924 number

Southern Minnesota runs on Central Time (CT) — CST (UTC −6) in winter, CDT (UTC −5) during Daylight Saving Time. Ten-digit dialing has been mandatory since January 30, 2024: dial 1, then the area code, then the seven-digit number, for every local call.
