  Area codes 541 and 458

Area codes 541 and 458 are telephone area codes in the North American Numbering Plan (NANP) for most of the U.S. state of Oregon, excluding only the northwestern corner of the state. The service area includes the cities of Eugene, Springfield, Corvallis, Albany, Grants Pass, Medford, Bend, Ashland, Klamath Falls, The Dalles, Burns, Lakeview, and Pendleton, as well as the coastal region from Lincoln County to the California border. Area code 541 was created in an area code split from area code 503 on November 5, 1995. Area code 458 was added to the same service area on February 10, 2010 to form an overlay.

History

[edit]

Area code 503 was used for the entire state of Oregon until November 5, 1995, when the numbering plan area was reduced to just the populous northwestern corner of the state, including Portland and Salem, and area code 541 began service for the rest of the state.[1] The dividing line ran east and south of Portland.

This was intended as a long-term solution, as northwest Oregon contains most of Oregon's population, and with it the great majority of Oregon's landlines and cell phones. However, by 2007, 541 was quickly exhausting central office codes, due to the proliferation of cell phones and pagers, particularly in Eugene, Corvallis and Medford.

To mitigate central office code exhaustion, the Oregon Public Utility Commission approved an overlay numbering plan with area code 458 for the entire area,[2] resulting in mandatory 10-digit dialing for that area.[3] Am overlay was chosen rather than a split to spare residents, particularly those east of the Willamette Valley, the expense of changing their numbers. Oregon's other NPA (503/971) already had this requirement. Ten-digit dialing was phased in beginning in July 2009, becoming mandatory in January 2010.[4] The first exchange to be issued in the 458 area code was 205 in Eugene in August 2011.

The numbering plan area is divided among four local access and transport areas (LATAs). Most of the numbering plan area is part of the Portland LATA, while the southwest portion is the Eugene LATA. Malheur County is part of the Boise/southern Idaho LATA and the Quinn, Oregon, exchange, in the Reno/northern Nevada LATA, while part of northeast Oregon is in the Spokane, Washington LATA

Area codes 541 and 458

View on Grokipedia
from Grokipedia
Area codes 541 and 458 are telephone area codes in the North American Numbering Plan (NANP) serving the majority of the U.S. state of Oregon, excluding the northwestern region encompassing Portland and Salem. These codes cover a vast expanse of central, eastern, southern, and western Oregon, including 28 counties and over 180 cities. Area code 541 was introduced on November 5, 1995, as a split from the original Oregon area code 503 to accommodate growing demand for telephone numbers outside the Portland metropolitan area. It serves major population centers such as Eugene (the second-largest city in Oregon), Bend, Medford, Springfield, Corvallis, and Albany. The region operates in the Pacific Time Zone (UTC-8/UTC-7 during daylight saving time). Due to projected exhaustion of available numbers in 541 by the early 2010s, area code 458 was implemented as an all-services overlay on February 10, 2010, covering the identical geographic territory without requiring changes to existing phone numbers. This overlay addressed the increasing need for central office codes (NXX) in the area, which includes diverse landscapes from the Cascade Mountains to the Pacific Coast and the high desert east of the Cascades. Both codes continue to support wireline, wireless, and VoIP services across the region.

Overview

Geographic Coverage

Area codes 541 and 458 serve most of the U.S. state of Oregon, covering approximately 28 of its 36 counties while excluding the densely populated northwestern urban corridor, which is instead served by area codes 503 and 971. This region encompasses central, eastern, southern, and portions of western and northern Oregon, providing telephone service to a diverse mix of urban, rural, and coastal communities. The counties fully or partially served by these area codes include Baker, Benton, Coos, Crook, Curry, Deschutes, Douglas, Gilliam, Grant, Harney, Hood River, Jackson, Jefferson, Josephine, Klamath, Lake, Lane, Lincoln (partial), Linn, Malheur, Marion (partial), Morrow, Sherman, Umatilla, Union, Wallowa, Wasco, and Wheeler. The boundaries align with Oregon's eastern and southern state lines in their entirety; the northern boundary generally follows the Columbia River, with exceptions in the excluded northwest; and the western boundary incorporates coastal territories from southern Lincoln County southward. Major population centers within this territory include Eugene (the largest city served), Bend, Medford, Springfield, Corvallis, Albany, Grants Pass, Ashland, Klamath Falls, The Dalles, Roseburg, and Redmond. In addition to Oregon, the area codes extend slightly into the northeastern corner of Del Norte County, California, a small rural pocket near the Oregon border that supports isolated communities. The entire service area operates within the Pacific Time Zone (UTC−8 standard time, UTC−7 daylight saving time).

Overlay System

Area code 458 was introduced as a full overlay on the existing 541 numbering plan area on February 10, 2010, to provide relief from central office code exhaustion without requiring a geographic split of the service territory. This overlay plan was approved by the Oregon Public Utility Commission in Order No. 08-528 on November 4, 2008, following a petition by Neustar Inc. in Docket UM 1380, ensuring continued service across the same expansive region in central, southern, and eastern Oregon. The implementation avoided the disruptions associated with area splits, such as the need for residents and businesses to change phone numbers based on location. The decision to implement the overlay stemmed from the projected exhaustion of available telephone numbers in the 541 area code by the first quarter of 2011, driven by rapid population growth in key metro areas like Bend and Eugene, as well as the widespread adoption of cell phones, fax machines, and other devices requiring dedicated numbers. These factors accelerated demand beyond initial projections following the 1995 creation of 541, necessitating additional capacity to support ongoing expansion in the region. To facilitate the transition, a permissive 10-digit dialing period ran from July 12, 2009, to January 10, 2010, during which callers could optionally use 10 digits for local calls within the 541 area to prepare for the overlay. On January 10, 2010, mandatory 10-digit dialing (including the area code) became required for all local and extended area service calls, with toll calls using 1 + 10 digits; this rule remains in effect today with no changes for the addition of 458. There is no geographic distinction between the two codes—both serve the identical territory, and assignments of new numbers default to 458 once 541 prefixes are depleted, preserving the unified service area. Existing telephone numbers with the 541 area code were unaffected by the overlay, allowing customers to retain their numbers indefinitely without any mandatory changes. However, businesses, residents, and service providers were encouraged to update directories, websites, and automated systems to include both area codes for compatibility, minimizing potential disruptions in call routing and customer outreach as 458 numbers proliferated. This approach has sustained telephone service reliability amid continued regional development.

History

Creation of Area Code 541

Area code 541 was established on November 5, 1995, as a geographic split from the existing area code 503 to address the growing demand for telephone numbers in Oregon under the North American Numbering Plan (NANP). Originally, area code 503 encompassed the entire state of Oregon since its assignment in 1947, but rapid population growth and increased telephone usage, particularly in urban centers, led to projections of its exhaustion by the end of 1995. The split was designed to relieve this pressure by reallocating numbering resources, with 541 assigned to serve central, eastern, and southern Oregon, while 503 was retained for the northwestern portion. The regulatory process began with an investigation by the Oregon Public Utility Commission (PUC), which held public hearings in Eugene on April 5, 1995, and Lincoln City on April 12, 1995, to gather input on relief options, including splits versus overlays. Following staff recommendations presented on May 2, 1995, the PUC approved the plan on May 4, 1995, in coordination with the NANP administration to ensure compliance with national numbering standards. This decision was driven by forecasts indicating that the new 541 area code would provide sufficient capacity until approximately 2010, while the retained 503 area code was projected to last until about 2005. The initial boundaries of area code 541 included all of Oregon east of the Willamette Valley and south of Salem, encompassing the Eugene local access and transport area (LATA), the Ontario region, areas east and southeast of the Cascade Range, and southern coastal communities, while excluding the Portland metropolitan area and northern coast, which remained under 503. To facilitate the transition, a permissive dialing period allowed both 7-digit and 10-digit local calls from November 5, 1995, to June 30, 1996, at 12:01 a.m., after which 10-digit dialing became mandatory within the affected regions. The split immediately impacted customers in central, eastern, southern, and coastal areas, requiring them to update their telephone numbers, reprogram equipment such as fax machines and security systems, revise printed directories, and replace signage in businesses and public facilities, particularly in rural and mid-sized communities like Eugene, Bend, and Medford. This change affected a significant portion of Oregon's telephone subscribers outside the northwest, minimizing disruption for Portland-area users who retained their existing 503 numbers.

Introduction of Area Code 458

The Oregon Public Utility Commission (OPUC) approved the introduction of area code 458 on October 21, 2008, as an all-services overlay to the existing 541 area code, following a recommendation from Neustar, Inc., the North American Numbering Plan Administrator (NANPA). This decision came after a public comment period from June 19 to August 6, 2008, during which the OPUC hosted open house meetings at 18 locations across the region to gather input from residents and stakeholders. The planning was driven by projections that the 541 area code would exhaust its available numbers by early 2011, necessitating relief to accommodate growing demand in southern and eastern Oregon. Industry participants, including telecommunications carriers, unanimously selected the overlay format over alternatives like a geographic split or concentrated overlay, as it preserved the existing numbering boundaries and minimized disruptions to interconnected communities without requiring number changes for current subscribers. Implementation proceeded on a 14-month timeline outlined in the OPUC's Order No. 08-528, with NANPA issuing a planning letter on November 19, 2008, to coordinate carrier activation. Public awareness efforts, led by the OPUC and supported by telecom providers, began in mid-2009 and included media notifications, a toll-free information line, website updates, and direct outreach to inform residents about the transition to 10-digit local dialing. Technical preparations focused on upgrading central office switches for 10-digit capability across the shared geographic area, with permissive 10-digit dialing starting July 12, 2009, and mandatory enforcement from January 10, 2010; no new boundaries were established, ensuring seamless coverage matching that of 541. New 458 numbers became available for assignment on February 10, 2010, the official activation date. Following rollout, area code 458 has primarily received new telephone number assignments, contributing to overall numbering efficiency in the overlay region. As of December 31, 2023, 458 had a utilization rate of 39.8% with 349,000 assigned numbers, while 541 stood at 49.1% utilization with nearly 2 million assigned numbers, indicating sufficient capacity without immediate need for additional relief planning. According to the October 2024 NANPA exhaust projection, the combined 458/541 numbering plan area is forecasted to exhaust in the second quarter of 2044. The overlay system requires 10-digit dialing for all local calls to distinguish between the two codes.

Central Office Prefixes for 541

The central office prefixes for area code 541 consist of the three-digit NXX codes that designate telephone exchanges serving various rate centers across western Oregon and a small extension into northern California. As of October 2025, approximately 784 prefixes remain active under 541, with new assignments directed to the overlay area code 458 since its introduction in 2010 to conserve numbering resources. These prefixes are grouped by rate centers, often corresponding to cities or communities, and reflect the area's diverse geography from urban centers to rural and coastal regions. Prefixes are categorized based on regional characteristics. Urban areas, such as those in Lane County (e.g., Eugene and Springfield), feature multiple prefixes like 344, 485, and 520, supporting high call volumes in population centers. In central Oregon's Deschutes County, Bend utilizes prefixes including 312, 388, and 548 for residential and business services. Southern Oregon's Jackson County, around Medford, employs prefixes such as 512, 535, and 779. Smaller urban or semi-urban rate centers like Corvallis in Benton County use 752 and 766. Rural and eastern areas, including Burns in Harney County (573) and Lakeview in Lake County (947), have fewer dedicated prefixes to cover sparse populations. Coastal regions, such as Coos Bay in Coos County, rely on 269 and 267, while eastern locales like The Dalles in Wasco County use 296 and 298. Some prefixes, such as those in the 200-299 range, were grandfathered from the pre-1995 area code 503 split and continue to serve legacy customers without change. A unique aspect of 541's prefix assignments is the single prefix 482, which serves a small pocket in California's Del Norte County near the Oregon border, historically tied to cross-state service continuity. No new central office codes have been assigned exclusively to 541 since the 458 overlay activation, preserving existing allocations while allowing ten-digit dialing across the shared territory.

Central Office Prefixes for 458

Area code 458 prefixes are assigned exclusively for new telephone services in the overlay region with 541, ensuring that existing 541 numbers remain unchanged and cannot be ported to 458. As of December 2025, approximately 213 active central office prefixes (NXX codes) are in use, representing about 27% utilization of available resources and reflecting gradual expansion since the code's activation in 2010. These assignments prioritize high-demand urban areas to accommodate growth, such as the Bend metropolitan statistical area, which has increased by over 30% since 2010 due to migration and economic development. The prefixes overlay the same geographic rate centers as 541, covering most of Oregon outside the Portland and Salem regions, but are strictly limited to Oregon without extension to adjacent areas like northern California. Allocations emphasize urban expansion, particularly in counties like Deschutes (Bend and Redmond), Lane (Eugene/Springfield), Jackson (Medford), and Linn (Albany), with sparser distribution in rural zones to support targeted infrastructure needs. Key rate centers include Eugene/Springfield with prefixes such as 201, 205, and 209; Bend with 202, 206, and 256; Medford with 225 and 226; Albany with 233 and 253; and emerging assignments in growth areas like Redmond with 312, activated primarily post-2010 to meet escalating demand.
