What Is an Overlay Area Code?
An overlay area code is a telecommunications system that adds a new area code to the same geographic region as an existing one. Instead of dividing a city or region and requiring some residents to change their phone numbers, authorities add the new code over the existing one. With this system, existing customers keep their current area codes and phone numbers, while service providers assign the new area code to some new phone lines and services.
Why Was 283 Created?
The 283 area code serves southwestern Ohio because the region faced a shortage of available phone numbers. The original 513 area code, which began serving the region in 1947, was quickly running out of available seven-digit phone number combinations. The North American Numbering Plan Administrator (NANPA) projected that the 513 area code would use up all its unassigned prefixes by the fourth quarter of 2023. To ensure that telecommunications providers could continue issuing new phone numbers to residents and businesses, the Public Utilities Commission of Ohio (PUCO) approved the 283 area code as an overlay. The new area code officially went into service on April 28, 2023.
