About 353 Area Code
Area code 353 serves southwestern and south-central Wisconsin as an overlay to area code 608, covering major population centers including Madison, Janesville, Beloit, La Crosse and Wisconsin Dells. Introduced on September 15, 2023, the code became one of the newest additions to the North American Numbering Plan and addresses number exhaustion in Wisconsin's fastest-growing metro area. The 353/608 overlay spans 21 counties from the Mississippi River to the state capital, supporting local voice and SMS-capable numbers used by government agencies, healthcare systems, tech companies, insurance carriers and tourism businesses across urban and rural communities.
The 353 region anchors Wisconsin's capital city economy, with major employers including Epic Systems (electronic health records), American Family Insurance, University of Wisconsin-Madison, and state government offices. Madison's tech sector earned recognition from Forbes as an information jobs hub, while the broader region supports advanced manufacturing (John Deere, Sub-Zero), food processing (dairy and meat products), and tourism operations along the Wisconsin River and Dells. Local businesses use 353 numbers for patient appointment reminders, customer support, policy services, campus communications and booking confirmations. A recognizable local area code drives higher answer rates compared to toll-free or out-of-state numbers because customers associate 353 and 608 with legitimate regional businesses rather than distant call centers.
FoneSwift displays current 353 inventory with live capability data on this page. Filter numbers by Voice, SMS and MMS support to match your communication needs. Area code availability shifts frequently as new assignments are distributed. If your preferred 353 number is unavailable, the paired 608 overlay serves the identical geographic region and offers additional inventory while maintaining the same local trust and recognition throughout southwestern Wisconsin.
When targeting Madison, the Dells or Mississippi River communities, display your 353 number in both standard and E.164 formats ((353) 555-1234 and +1 353 555 1234) for maximum compatibility across devices and platforms. Register A2P messaging if you run SMS campaigns to meet carrier compliance requirements and avoid filtering. Porting is available for eligible numbers. Check the porting guide for carrier-specific timelines. Many businesses port existing 608 numbers to FoneSwift while keeping the same digits to preserve customer recognition and maintain service continuity during transitions.

How Does Local 353 Phone Numbers Work?
