Why Metro Cleveland Has 2 Area Codes
When a region uses more numbers than one code can hold, new codes are overlaid on the same territory rather than forcing anyone to change numbers. Metro Cleveland now uses 216 and 440: same neighborhoods, ten-digit dialing, and every one of them covered by its own guide above.

How Ohio Got Its Codes
Every Ohio area code, in the order it entered service. Splits carved new regions; added codes overlay existing ones, which is why ten-digit dialing is standard.
