About Area Code 436
Area code 436 is a North American Numbering Plan (NANP) area code that has been in service since 2024. It is administered by NANPA on behalf of the FCC and serves the Ohio region anchored on Columbus.
436 is an overlay code, which means it shares its geographic boundaries with one or more existing area codes (614). Overlays are created when a region exhausts the supply of phone numbers in its original area code. Within an overlay region, residents must dial all 10 digits even for local calls, because the same 7-digit number can exist under multiple area codes.
Mobile numbers in 436 are portable: a person who moved away from Columbus may still carry a 436 mobile number on their device. If you receive an unexpected call from a 436 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 (614). See the related codes section below to explore the rest of Ohio.
