Oregon has 4 active area codes as of 2026, covering the state through a mix of original 1947 assignments, geographic splits, and modern overlays. This guide walks through the full list, which regions each code serves, the order they came online, and where new codes are most likely to land next.
The Short Answer
Oregon currently has 4 active area codes in service. The count reflects a combination of population growth, the rise of mobile lines, and the way modern numbering allocates blocks — every line activated, whether a cellphone, a business desk line, a VoIP number, or a connected device, consumes a slot in the pool.
By population, Oregon ranks #27 nationally with roughly 4,272,371 residents as of the most recent estimates. That puts the state’s area code count in line with its population peers — denser, faster-growing states need more codes; smaller states need fewer.
The Full List of Oregon Area Codes
The active area codes serving Oregon are listed below, in numerical order. Where a code is an overlay or a split-off from an earlier code, that relationship is noted.
- 503 — Northwestern Oregon (Portland, Salem, Astoria)
- 541 — Oregon outside the northwestern corner (Eugene, Medford, Bend, Pendleton)
- 971 — Northwestern Oregon (Portland, Salem, Astoria) (overlay of 503)
- 458 — Oregon outside the northwestern corner (Eugene, Medford, Bend, Pendleton) (overlay of 541)
How Oregon’s Area Codes Grew Over Time
Oregon received its first area code, 503, when the North American Numbering Plan launched in 1947. That single code initially covered the entire state, and subsequent splits and overlays narrowed it over the decades that followed.

- 1995 — 541 split off from 503 on November 5, 1995, taking everything outside the northwestern corner, including Eugene, Medford, Bend, and Pendleton.
- 1999 — 971 created on July 1, 1999 as a concentrated overlay of 503 across most of northwestern Oregon, introducing ten-digit dialing to the Portland area.
- 2008 — Clatsop and Tillamook counties, initially exempted, were added to the 503/971 overlay on April 27, 2008, completing its coverage.
- 2010 — 458 activated on February 10, 2010 as an overlay of 541 covering the same service area across southern, central, and eastern Oregon.
Oregon Area Codes by Region
Northwestern Oregon (503, 971): Portland, Salem, Astoria, and the surrounding Willamette Valley counties. 503 is the original 1947 code; 971 was added as an overlay in 1999 and extended to full coverage in 2008.
Rest of Oregon (541, 458): Everything outside the northwestern corner, including Eugene, Corvallis, Medford, Bend, Klamath Falls, Pendleton, and the southern coast. 541 split off from 503 in 1995; 458 overlay added in 2010.
What’s Next for Oregon Area Codes
Oregon’s two numbering plan areas were each relieved by an overlay rather than a further split, which keeps both pools intact statewide. NANPA’s most recent NPA exhaust analysis shows neither the 503/971 complex nor the 541/458 complex on the near-term relief schedule, so no new Oregon area code is projected for the next several years. Growth pressure, when it returns, is most likely in the Portland metro served by 503/971.
Frequently Asked Questions
How many area codes does Oregon have right now?
Oregon has 4 active area codes in service across the territory it covers, including any overlays that share geography with an older code.
What is the oldest area code in Oregon?
503 is the oldest active area code in Oregon, assigned in 1947 when the North American Numbering Plan launched. It remains in service today, though its geographic footprint has typically been reduced by subsequent splits and overlays.
What is the newest area code in Oregon?
The most recent area code addition to Oregon was 458, activated in 2010. New phone lines provisioned in its service area are increasingly drawn from this code as older overlays approach exhaustion.
Why does Oregon need so many area codes?
Population growth combined with the proliferation of mobile lines, business direct-dial numbers, VoIP services, and connected devices has exhausted older codes faster than the original 1947 plan anticipated. Each new area code adds roughly 7.9 million additional phone numbers to the regional pool.
How many area codes does Oregon have?
Oregon has 4 active area codes: 503, 541, 971, and 458. The state is divided into two regions, each served by two overlaid codes. 503 and 971 cover the northwestern corner around Portland, while 541 and 458 cover the rest of the state.
What area code is Portland, Oregon?
Portland uses 503 and its overlay 971. 503 is the original code dating to 1947, and 971 was added in 1999 to relieve number shortages in the metro. New lines in the Portland area may be assigned either code, and ten-digit dialing is required.
What area code is Eugene and Bend?
Eugene, Bend, Medford, and most of Oregon outside the Portland area use 541, with 458 as its overlay. 541 split from 503 in 1995, and 458 was added in 2010. Both serve the same large service area covering southern, central, eastern, and coastal Oregon.
Is 971 a real Oregon area code?
Yes. 971 is an overlay of 503 serving northwestern Oregon, including Portland, Salem, and Astoria. It went into service in 1999 and was extended to cover Clatsop and Tillamook counties in 2008. A 971 number is geographically the same as a 503 number.
