The 812 area code serves southern Indiana including the city of Evansville, Terre Haute, and Bloomington. It also covers the Indiana sections of the Louisville and Cincinnati metropolitan areas.
The North American Numbering Plan (NANP) uses a three-digit telephone number prefix to mathematically encode its members’ territories into numbering plan areas (NPAs).

What is an area code?
An area code is a series of digits that identify a particular geographic region in the United States. They are also used to locate the proper fax number when making an outbound fax call.
The first three digits of an area code correspond with the physical geographic region, followed by a country code and then the telephone prefix. The prefix is usually a three-digit code that indicates a smaller geographic region within the larger area.
Area codes were developed in 1947 to overcome the shortage of telephone numbers in North America through the North American Numbering Plan. These digits were assigned based on theoretical usage of rotary phones at the time, with areas with high population receiving short codes that required only five clicks to dial, while areas with low populations were given longer codes that required more manual rotation.
In order to ensure a continuing supply of phone numbers, the North American Numbering Plan requires area codes to be refreshed when they reach exhaustion. This process is called an “overlay.” A new code will overlay the existing one to serve the same geographic area as the old one. The overlay will be available for all customers in the area, and the existing code will not be active for any new calls.
What is the 812 area code?
The 812 area code is a part of the North American Numbering Plan (NANP). It serves the southern portion of Indiana, including the cities of Bloomington, Evansville and Terre Haute.
In the NANP, a telephone number prefix, usually called the area code, mathematically encodes a member’s territory into numbering plan areas (NPAs). It also determines local call routing and toll charges, as well as time zones.
A business phone number with an area code gives your company a presence in a particular city or region, giving you a better chance of attracting customers. It also saves your business money by reducing your phone bill.
You can get a business phone number in the 812 area code with a digital telephone service from JustCall. It’s affordable and easy to use.

No hidden costs and a simple, cheap price structure make it a perfect choice for any small or medium-sized business.
How is the 812 area code different from other area codes?
When dialing a number, the three-digit 812 area code indicates that the call is coming from Indiana. This is a great feature to have on your business’s phone numbers, as it can help you appear more local to prospective customers.
The 812 area code covers the city of Indianapolis and many surrounding areas, including the larger cities of Evansville, Bloomington, and Terre Haute. In addition, this area code includes a large number of smaller communities throughout the state.
Until recently, the 812 area code has been the only original area code in southern Indiana that still had its boundaries intact since it was established in 1947. However, the demand for telephone service in that area has grown to the point where numbers have become scarce.
This has led the Indiana Utility Regulatory Commission (IURC) to adopt an overlay to resolve the 812 area code numbering shortage. The overlay will allow for a new area code to be assigned over the same geographic area as the existing 812 area code, without requiring that customers change their phone numbers.
How does the 812 area code work?
The 812 area code is used for a number of cities in southern Indiana including Evansville, Bloomington and Terre Haute. It has been in place since 1947 and has remained the same for decades.
When it comes to telephone numbers, the 812 area code is one of the few original area codes that have stayed intact. It is a good option for small businesses, as it can give your company a local presence in your community and help you attract more customers.
However, as is the case with many other areas, the 812 area code will run out of phone numbers soon. Fortunately, the telecommunications industry has filed a request with the Indiana Utility Regulatory Commission to create a new area code called an overlay that would cover the entire southern and south-central Indiana region.
The overlay method, which has been implemented in recent years for other area codes in the state, will allow the telecom industry to continue to supply the existing 812 numbers for existing and future customers while creating new ones with the 930 area code.
The only downside to this new alternative is that customers will have to use 10-digit dialing (area code + number) for all local calls, whether they are long distance or not.
