Identify Phone Number Location Using South Dakota Area Codes

To identify the location of an South Dakota phone number, you need to understand the North American Numbering Plan (NANP) structure that all Alabama numbers follow: +1 NPA NXX XXXX.

• +1 - Country code indicating the United States
• NPA - The area code reveals the geographic region where the number was originally assigned
• NXX - Central office code that locates the specific neighborhood and identifies the service provider
• XXXX - Subscriber number identifies the individual phone line within that local exchange

The area code (NPA) is your key to determining location. By matching the three-digit area code to South Dakota's regional assignments, you can identify which part of the state the phone number originates from. Each area code corresponds to specific cities and counties throughout South Dakota, making it possible to narrow down the caller's general location.
