To ensure a continuing supply of telephone numbers, the boundary between the current geographic region served by the 323 and 213 area codes will be eliminated so that both area codes will serve the same geographic region. This is known as a boundary elimination area code overlay. Get ready to change the way you dial your calls!
In this case, the boundary line between the 323 and 213 area codes is being eliminated so that the existing 213 area code will serve the same geographic region as the existing 323 area code, and conversely, the existing 323 area code will serve the same geographic region as the existing 213 area code. In other words, the two areas served by the 213 and 323 area codes are being combined and telephone numbers for either area code will be assigned in the new combined area.
A boundary elimination area code overlay does not require customers to change their existing area code but does require customers to dial at minimum the area code + telephone number on every call, including calls within the same area code.
