Area code 574 is a telephone
area code in the North American Numbering Plan (NANP) for the northern part of the U.S. state of Indiana. It was created in a three-way area code split from area code 219
in 2002.
History
In 1947,
Fort Wayne, received area code 219.[1]
The northern third of Indiana was served by area code 219 for 54 years. By the end of the 20th century, 219 was on the verge of exhaustion of central office prefixes. It was decided to implement a three-way split of the 219 territory. As the result of a random drawing, the middle portion, surrounding South Bend, received area code 574. The eastern portion (
Fort Wayne) became area code 260, while Northwest Indiana retained 219. The area codes split on January 15, 2002, with permissive dialing continuing until June 14, 2002.[2]
Prior to October 2021, area code 574 had telephone numbers assigned for the
National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021.[3]
