📍 Geographic Location of Indiana
Overview of Area Code 930
Area code 930 is a geographic North American Numbering Plan (NANP) code serving the state of Indiana, United States. It was introduced on June 1, 2015, as an overlay for the existing area code 812, which covers a large portion of southern Indiana. The overlay was implemented to meet the growing demand for new telephone numbers in the region, driven by population growth and increased use of mobile and data services.
Geographic Coverage
Area code 930 serves the same geographic area as 812, encompassing a broad region of southern Indiana. Key cities and towns within this area include Bloomington, Evansville, Terre Haute, New Albany, Jeffersonville, Clarksville, Columbus, Seymour, and Vincennes. The region is characterized by a mix of urban centers, suburban communities, and rural areas, with a diverse economy spanning manufacturing, education, healthcare, and agriculture.
Dialing Procedures
Since 930 is an overlay, ten-digit dialing is mandatory for all local calls within the 812/930 area. This means that callers must dial the area code plus the seven-digit local number for every call, even for calls to numbers within the same area code. For calls from outside the 812/930 region, the full ten-digit number preceded by the country code is required: +1 930 XXX XXXX for international callers. For example, to call a business in Evansville from abroad, one would dial +1 930 555 0123.
For local callers within the 812/930 area, the same ten-digit format applies: 930 XXX XXXX. This change was necessary to accommodate the overlay and ensure that all numbers can be routed correctly.
Overlay and Numbering Resources
The introduction of 930 did not require existing 812 customers to change their numbers. Instead, new lines and services in the region are assigned numbers with the 930 area code. This overlay approach ensures a continuous supply of telephone numbers without disrupting existing subscribers. The Indiana Utility Regulatory Commission (IURC) oversees the allocation of numbering resources in the state, working in coordination with the North American Numbering Plan Administrator (NANPA).
Caller Instructions
- Local callers (within 812/930): Always dial 10 digits: area code + local number.
- Long-distance callers within the US/Canada: Dial 1 + 10 digits (e.g., 1 930 555 0123).
- International callers: Dial the US country code (+1) followed by the 10-digit number (e.g., +1 930 555 0123).
It is important to note that area code 930 is not a separate geographic region; it is an overlay for the entire 812 area. Therefore, there is no distinction in coverage between 812 and 930; both serve the same geographical footprint.
