- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 743 number on request, especially for active overlay codes. You won’t usually get to pick the specific number, but you’ll get a working line in the area code. This is the cheapest option for anyone who doesn’t need a particular number.
- Port an existing 743 number. If you already have a 743 phone number with another carrier, you can transfer it (port it) to a new service provider while keeping the number. This works for landlines, cell phones, and VoIP services, though landlines outside of North Carolina sometimes can’t accept inbound ports of 743 numbers due to 911 routing rules.

Is 743 an overlay or a split from another area code?
743 is an overlay of area code 336. It was added to the same geographic territory in 2016 because 336 was projected to exhaust its available numbers. Existing 336 subscribers kept their numbers; 743 numbers were issued for new service.
When did ten-digit dialing become required in the 743 / 336 area?
Permissive ten-digit dialing began on October 24, 2015, when 743 was formally activated. Mandatory ten-digit dialing took effect on April 23, 2016, for all local calls within the 336/743 numbering plan area.
Where did area code 336 come from before 743 was added?
Area code 336 was created on December 15, 1997, through a geographic split of area code 910, which had grown too large to sustain. When 336 itself neared exhaustion in the mid-2010s, regulators chose an overlay rather than another split, producing area code 743.
