Nebraska area codes
The table below lists every active Nebraska area code with its coverage, service date and prefix count. 2 of the 3 codes are overlays — added on top of existing territories as numbers ran short.
Geographically the map reads: 402 (Omaha), 308 (Grand Island), 531 (Omaha). Each code page lists its full coverage down to individual rate centers.
Overlay territory: 402/531 — same geography, several codes, ten-digit local dialing.
Recent numbering history: 531 arrived in 2011 — an overlay added as existing codes approached exhaust.
Clocks differ across the state's codes (Central, Mountain) — worth checking before a callback.
308, in service since 1955, anchors Grand Island, carries 461 active prefixes across 167 rate centers, split among 62 carriers. 286 of its prefixes are pooled — shared between carriers in thousands-number blocks. It is one of the few NANP area codes whose territory spans two time zones. NANPA projects its capacity to last until 1Q 2057 — no relief needed for decades. Local calls can still be dialed with seven digits — increasingly rare in the NANP.
402, in service since 1947, anchors Omaha, carries 782 active prefixes across 281 rate centers, split among 57 carriers. 563 of its prefixes are pooled — shared between carriers in thousands-number blocks. It is the oldest area code in Nebraska, in service since 1947. NANPA projects its capacity to last until 1Q 2040 — no relief needed for decades. Local dialing is ten digits.
531 has served Omaha since 2011, carries 260 active prefixes across 104 rate centers, split among 37 carriers. 260 of its prefixes are pooled — shared between carriers in thousands-number blocks. NANPA projects its capacity to last until 1Q 2040 — no relief needed for decades. It was created from 402. Local dialing is ten digits.
Note that toll-free codes (800, 833, 844, 855, 866, 877, 888) sit outside this list — they have no geographic tie to Nebraska or anywhere else, and are assigned individually from the national SMS/800 registry.
As everywhere in the NANP: these codes say where numbers were issued, not where callers are. Per-code pages break coverage down to rate centers and prefixes.
| Code | Major area | In service | Overlay complex | Prefixes |
|---|---|---|---|---|
| 308 | Grand Island | 1955 | — | 461 |
| 402 | Omaha | 1947 | 402/531 | 782 |
| 531 | Omaha | 2011 | 402/531 | 260 |
