Covering about 1.5 million, the 220 area code overlays 740 in southeast Ohio, a region of rolling hills and small-town roots. Newark (pop. 50,315), the largest hub, blends manufacturing (Owens Corning) with historic charm, like its ancient earthworks. Zanesville (pop. 24,765) adds pottery fame and river trade, while Marietta (pop. 13,385) offers Ohio River history and oil roots. This area excels in industry, agriculture, and a quiet tourism draw, giving businesses a foothold in Ohio’s heartland. 220 boosts 740’s capacity, with 614 nearby, but its rural-industrial mix offers a distinct, grounded appeal.
