North Carolina area codes
North Carolina uses 10 area codes, with 1 more assigned but not yet in service. The oldest is 704, in service since 1947; the newest is 472, from 2022. Across them 5,581 of 8,646 possible number blocks are allocated, 64.6% of capacity. 910, 336, 704 and 919 are at or past 95%, which is why new numbers there come from overlays rather than the original code. AT&T holds 22.9% of the 5,581 assigned blocks across the state, ahead of Verizon at 13.7%; a further 10.2% sits with CLEC and VoIP holders outside the national carriers. In the 33 days to 30 October 2026, FTC complaints named a North Carolina caller ID 6,217 times – 2.7% of all complaints in the window, most often 252 with 933 (51st of 422 nationally). NANPA has relief planning under way for 451 and 828, so more codes are coming. NANPA records 640 rate centers across the state's codes.

Block share is share of allocated number blocks, not of subscribers. Complaint counts cover 28 Sep – 30 Oct 2026 and reflect spoofed caller IDs as much as real calls.
How full North Carolina’s codes are
A code holds at most 786 blocks of 10,000 numbers each. When a code fills up, the administrator does not reclaim numbers – it adds an overlay, and from then on new numbers in the same area come from the new code.
Full or nearly full
451 is in service with no blocks assigned at all, so nobody can hold a number there yet – a caller ID showing one is necessarily spoofed.
Who holds the number blocks
Counted from every assigned block in the state: 5,581 blocks, each with the holder NANPA recorded for it. Percentages are measured, not estimated.
| Holder | Blocks | Share of North Carolina | Largest in |

| AT&T | 1,279 | 22.9% | 6 codes |
| Verizon | 767 | 13.7% | – |

“Other CLEC / VoIP” is not one company: it is every holder outside the national carriers counted together, which is what resellers and app-based numbers look like in the records. This is allocation, not subscribers.
Spam complaints naming North Carolina codes
FTC Do Not Call complaints where the caller ID shown was a North Carolina number, 28 Sep – 30 Oct 2026 (33 days). Caller IDs on spam calls are routinely faked, so these are complaints about the code, not calls proven to come from it.
What is coming next
One code is assigned to North Carolina but not yet in service. Numbers in them cannot exist yet, so a call displaying one today is spoofed.
NANPA has relief planning open for 451, 828 – the step that comes before a new overlay is announced. Watch these codes if you need to know whether dialing or new-number availability is about to change.
