Arkansas area codes
Arkansas uses 4 area codes. The oldest is 501, in service since 1947; the newest is 327, from 2024. Across them 2,028 of 3,144 possible number blocks are allocated, 64.5% of capacity. 870 is at or past 95%, which is why new numbers there come from overlays rather than the original code. AT&T holds 37.9% of the 2,028 assigned blocks across the state, ahead of Verizon at 9.9%; a further 11.8% sits with CLEC and VoIP holders outside the national carriers. In the 33 days to 30 October 2026, FTC complaints named an Arkansas caller ID 2,029 times – 0.9% of all complaints in the window, most often 870 with 907 (60th of 422 nationally). NANPA records 417 rate centers across the state's codes.
All 4 codes
| Code | In service | Blocks used | Largest holder | Complaints | Shares area with |
|---|---|---|---|---|---|
| 327 | 2024 | 43/786 | Onvoy 34.9% | 19 | 870 |
| 479 | 2002 | 569/786 | AT&T 41.5% | 420 | no overlay |
| 501 | 1947 | 631/786 | AT&T 40.4% | 683 | no overlay |
| 870 | 1997 | 785/786 | AT&T 35% | 907 | 327 |
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 Arkansas’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.

“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 Arkansas codes
FTC Do Not Call complaints where the caller ID shown was a Arkansas 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.
