Are You in One of Indiana’s Original Two Area Codes?
Every time you dial someone's number here in Indiana, you are first punching in their area code. Indiana has eight different area codes in 2022, but is your area using one of the original two area codes?
2022 marks the 75th anniversary of telephone area codes in the United States. Area codes aren't something we really tend to put much thought into nowadays. We simply type in someone's ten-digit phone number into our phones and go about our day. However, back in 1947, when area codes were first introduced, they were a pretty big deal. Then, there were only three area codes in the state of Indiana. One of our sister stations in another market took a deep dive into Michigan area codes, so I thought it might be interesting to find out if you are a part of one of the two original area codes in Indiana.
Indiana's Original Area Codes
In 1947, the Bell Telephone System (now AT&T) gave out 86 different area codes across the United States. Two of those area codes were given to Indiana. The area codes essentially split the state in half, with area code 317 serving Indianapolis north to Michigan, and area code 812 serving Bloomington south to Kentucky. So, we here in the Evansville area have one of the OG area codes. That's pretty interesting! According to telecomindiana.com, the map below:

The Evolution of Indiana's Area Codes
A year later, in 1948, Bell gave Indiana its first new area code. The northern area code, 317 was split, giving 317 to Indianapolis and central Indiana and a new 219 area code to northern Indiana.
Indiana kept those same three area codes until its next addition in 1997. That's when Indianapolis was placed in a 317 bubble, and the rest of the original 317 area was given a 765 area code.
The next area code split in Indiana occurred in 2002 when the 291 area code was split into three codes. The area code 219 was given to the western part of that area, 574 was given to the central, and 260 was assigned to the eastern portion of the original 219 area code.
In 2015 the original 812 area code got an overlay. According to Twilio.com:
An Area Code Overlay is an area code that covers the same geographical space as another area code. In North America, each area code has a potential capacity of around 8 million unique phone numbers — 7,919,900, to be exact. Many area codes have exhausted all possible phone numbers, so one or more area codes are added to accommodate.
So, at that time, 812 area code users who got a new phone line prior to 2015 were given the area code 930. Likewise, in 2016, the latest change to Indiana's area codes came with the 317 area code receiving an overlay with the new 463 area code.
According to telecomindiana.com,
No further area code relief is expected in Indiana until 2032 for 765 and more than 30 years for all other Indiana area codes.
