Rhode Island area codes
The table below lists every active Rhode Island area code with its coverage, service date and prefix count.
Geographically the map reads: 401 (Providence). Each code page lists its full coverage down to individual rate centers.
Time zone is uniform across the state's codes: Eastern.
A statewide single code is getting rare in the NANP — most states have long since added overlays. 401 still covers everything from Providence to Newport on one code.
401 has served Providence since 1947, carries 578 active prefixes across 25 rate centers, split among 38 carriers. 420 of its prefixes are pooled — shared between carriers in thousands-number blocks. It is the only area code serving Rhode Island. NANPA projects its capacity to last until 2Q 2051 — no relief needed for decades. Local calls can still be dialed with seven digits — increasingly rare in the NANP.
Note that toll-free codes (800, 833, 844, 855, 866, 877, 888) sit outside this list — they have no geographic tie to Rhode Island 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 |
|---|---|---|---|---|
| 401 | Providence | 1947 | — | 578 |
