About Area Code 740
Area code 740 is a North American Numbering Plan (NANP) area code that has been in service since 2000. It is administered by NANPA on behalf of the FCC and serves the Ohio region anchored on Newark.
740 now shares its territory with an overlay code (220). 10-digit dialling is required for local calls within this region because the same 7-digit number can be assigned under either code.
Mobile numbers in 740 are portable: a person who moved away from Newark may still carry a 740 mobile number on their device. If you receive an unexpected call from a 740 number, run it through the reverse lookup tool above for the most accurate, free identification.
If you live or do business in Ohio, you may also interact with neighbouring or overlay codes (220). See the related codes section below to explore the rest of Ohio.
