About the 618 region
618 covers Southern Illinois in Illinois, including Albion, Altamont, Alton, Anna and Ashley. The code has been in service since 1947 and is one of the original North American area codes.
As the Southern Illinois region grew, 618 ran low on available numbers, so 730 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.
