Introduction
The 458 area code serves a vast swath of Oregon as an overlay of the established 541 area code — covering virtually all of the state outside the Portland-Salem corridor, from Eugene and Corvallis through the Cascades to Bend, south to Medford and Ashland near the California border, and east across the high desert communities of Klamath Falls, Pendleton, and La Grande. Introduced in 2010 to address number exhaustion in the sprawling 541 pool, the combined 458/541 footprint spans more than 85,000 square miles — leaving only the northwestern corner of the state, served by 503 and 971, outside its reach.
The Oregon Public Utility Commission approved 458 as an overlay rather than a geographic split specifically to spare existing 541 customers, particularly those east of the Willamette Valley, the cost and disruption of a forced number change. The overlay took effect on February 10, 2010, after ten-digit dialing was phased in starting in mid-2009, and the first 458 exchange was issued in Eugene in August 2011. Because it's an overlay rather than a split, a 458 number carries exactly the same local standing as a legacy 541 number anywhere in the shared footprint.
- Overlay on 541, effective February 10, 2010, covering all of Oregon outside the Portland-Salem area
- Mandatory 10-digit dialing throughout the shared 458/541 footprint since January 2010
- First 458 exchange issued in Eugene in August 2011
What the 458 Area Code Covers

Area code 458 shares the entire territory of 541, covering virtually all of Oregon except the Portland-Salem area served by 503/971. Eugene, home to the University of Oregon and roughly 178,000 residents, serves as the largest city in the coverage area, sitting in Lane County. Corvallis, home to Oregon State University and seat of Benton County, and Bend, in Deschutes County and currently the fastest-growing sizable city in Oregon, are also major population centers. The area also includes Medford and Ashland in Jackson County's Rogue Valley, coastal communities of Coos Bay and Newport, and eastern Oregon communities including Pendleton, La Grande, and Klamath Falls.
In total, the 458/541 footprint reaches roughly 28 Oregon counties, stretching from the Willamette Valley farmland south of Eugene, across the Cascade Range, to the high desert around Bend and Klamath Falls, and out to the agricultural and ranching communities of the state's eastern border. It's one of the largest single-overlay coverage areas in the country by geography, even though its combined population is a fraction of the Portland metro's on 503/971.
Crater Lake National Park, near Klamath Falls in the southern part of the footprint, protects the deepest lake in the United States — 1,949 feet at its deepest point, formed when Mount Mazama collapsed in a massive eruption roughly 7,700 years ago. Established in 1902, it's the fifth-oldest national park in the country and one of the region's most consistent tourism draws, pulling visitors through Medford and Klamath Falls year-round on their way to and from the caldera rim.
Nearby Ashland anchors its own year-round tourism economy around the Oregon Shakespeare Festival, founded in 1935 by Angus L. Bowmer and now the largest repertory theater in the country, staging roughly ten productions a season across three stages and drawing about 350,000 visitors annually to a town of barely 21,000 residents. Between Crater Lake's natural draw and OSF's cultural one, the Rogue Valley section of the 458 footprint supports a hospitality and tourism economy that rivals its timber and agricultural base in scale.
Businesses that instead need a local presence inside the Portland-Salem corridor are outside the 458/541 footprint entirely; see our guide to the 971 area code, the overlay covering Portland, Salem, and the Silicon Forest tech corridor on 503.
Phone Number Format and Dialing Guide

All 458 area code numbers follow the NANP 10-digit format: 458-XXX-XXXX. Because 458 is an overlay of 541, mandatory 10-digit dialing applies to all calls within the coverage region, including calls between two 541 numbers or two 458 numbers on the same exchange. For international callers, the correct format is +1 458 XXX XXXX. The 458/541 coverage area operates on Pacific Time.
Industries and Economy in the 458 Region

Higher education and research are foundational economic drivers across the 458 region. The University of Oregon in Eugene and Oregon State University in Corvallis together employ tens of thousands and generate significant economic activity across the Willamette Valley. Outdoor recreation and tourism represent a second major economic driver, particularly for Bend's craft-brewing and ski-resort economy, Ashland's Oregon Shakespeare Festival tourism, and the coastal communities. Timber, agriculture, and fishing remain important industries in the rural 458/541 counties, and Bend in particular has drawn a growing wave of remote-work technology professionals over the past several years.
Bend backs up its "Beer City USA" reputation with more than 20 breweries inside city limits — a city of roughly 100,000 people supporting one of the highest breweries-per-capita rates in the country, anchored by Deschutes Brewery, the region's most recognized name. That brewing scene, paired with Mount Bachelor's ski resort and the Deschutes River running straight through downtown, has turned outdoor recreation and hospitality into one of Central Oregon's largest employment sectors, alongside the remote-work tech professionals increasingly relocating there for the same lifestyle draw.
Eugene's identity as "TrackTown USA" runs directly through the University of Oregon's Hayward Field, home to the Ducks' track and field program since 1921 and rebuilt in 2018–2020 with lead funding from UO alumnus and Nike co-founder Phil Knight. Knight sold running shoes out of the back of his car at Hayward Field meets in Nike's earliest days, and the venue went on to host the 2021 US Olympic Trials and the 2022 World Athletics Championships — the first time that event had ever been held in the United States. That running culture, and the Nike connection it produced, makes Eugene a genuine economic and cultural anchor for the entire 458 footprint, not just a university town.

Getting a 458 Area Code Phone Number
Obtaining a 458 area code number is straightforward through a traditional carrier or a cloud VoIP provider. For businesses outside the 458/541 region that need a local Oregon presence — whether for university partnerships, outdoor recreation industry outreach, or reaching the growing Bend technology community — letsdial allows you to activate a 458 number in minutes without a physical Oregon office, with number porting and no long-term lock-in. Because 458 and 541 draw from the same shared pool, there's no meaningful difference in local credibility between the two — a new business is just as likely to be issued one as the other, and customers across Eugene, Bend, or Medford won't treat either prefix as more or less authentically Oregonian.
- Cloud VoIP platform — search available 458 numbers and activate an Oregon line the same day, with no hardware to install or physical office required.
- Port an existing 541 or 458 number — move your current number to a new provider at no charge, with no downtime for incoming calls during the switch.
- Traditional carrier or landline — still an option for a physical office in the region, though slower to provision and harder to scale across multiple locations.
Spam, Robocalls, and How to Stay Safe

Like all US area codes, 458 numbers are used in caller ID spoofing campaigns. Common fraud tactics include robocalls impersonating Pacific Power or other regional utility providers, phishing calls targeting University of Oregon and Oregon State students with fake financial aid or IT helpdesk calls, and scams targeting vacation rental bookings in the outdoor recreation communities. Register at donotcall.gov and report suspicious calls to the FTC at reportfraud.ftc.gov.
Legitimate businesses calling into this region face the flip side of that same problem: an unsigned outbound call can land as "Spam Likely" even when it's a genuine Bend contractor or a Eugene-area service business calling a real customer. STIR/SHAKEN attestation, which cryptographically verifies that a caller ID hasn't been spoofed, keeps a real 458 business number from getting caught in the same filters built to catch the scammers described above — worth checking for before choosing a provider.
458 is officially documented under the North American Numbering Plan, which governs area code assignments across the US, Canada, and the Caribbean.
Conclusion
The 458 area code overlays 541 across nearly the entire state of Oregon outside the Portland-Salem corridor, from the university towns of Eugene and Corvallis to the fast-growing Bend technology and recreation economy, the Rogue Valley, and the coast. Because it's an overlay rather than a split, a 458 number carries the same local standing as a legacy 541 number anywhere in that footprint — and letsdial lets a business activate one in minutes, with free porting and no physical Oregon office required.
