Nebraska area codes
Nebraska uses 3 area codes. The oldest is 402, in service since 1947; the newest is 531, from 2011. Across them 1,514 of 2,358 possible number blocks are allocated, 64.2% of capacity. 402 is at or past 95%, which is why new numbers there come from overlays rather than the original code. Across the state no single national carrier holds the most blocks: 23.6% sits with CLEC and VoIP holders counted together, ahead of Lumen at 17.8%. In the 33 days to 30 October 2026, FTC complaints named a Nebraska caller ID 1,360 times – 0.6% of all complaints in the window, most often 402 with 923 (55th of 422 nationally). The state spans 2 time zones (Central and Mountain); 308 crosses a zone boundary alone. NANPA records 553 rate centers across the state's codes.
All 3 codes
| Code | In service | Blocks used | Largest holder | Complaints | Shares area with |
|---|---|---|---|---|---|
| 308 | 1955 | 465/786 | Other CLEC / VoIP 33.1% | 213 | no overlay |
| 402 | 1947 | 782/786 | Windstream 25.6% | 923 | 531 |
| 531 | 2011 | 267/786 | Onvoy 24% | 224 | 402 |
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 Nebraska’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 Nebraska codes
FTC Do Not Call complaints where the caller ID shown was a Nebraska 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.

402 – 923 FTC complaints in the 33 days to 30 October 2026, 55th of 422 codes nationally. Those are complaints about the caller ID shown, and spam callers routinely fake a local-looking number, so this says the code is imitated often, not that the calls come from there.
Which carrier holds the most Nebraska numbers?
No one carrier does. 23.6% of the 1,514 number blocks assigned across Nebraska are held by CLEC and VoIP providers outside the national carriers – resellers and app-based numbers look like this in the records. The largest named carrier is Lumen with 17.8%. This is allocation of blocks by the numbering administrator, not a count of subscribers – people keep their numbers when they switch carriers.
