from Grokipedia
Area code 479 is a area code within the (NANP) serving northwestern in the United States, encompassing 15 counties and over 100 cities, including major population centers such as Fort Smith, Fayetteville, Springdale, Rogers, and Bentonville. Established on January 19, 2002, as the 316th area code in the NANP and the third in Arkansas, it was created through a geographic split of the original to address the rapid and increasing demand for telephone numbers in the northwest region, leaving 501 to cover around . The split allowed for the redistribution of numbering resources without immediately requiring an overlay, and 479 remains the sole area code for its service territory, operating in the (UTC-6:00, with observance). The region covered by 479 is known for its economic vitality, driven by industries such as retail (home to Walmart's headquarters in Bentonville), education (with the in Fayetteville), and , contributing to a of approximately 1,040,000 residents (2024 est.). While no overlays currently exist, projections indicate potential numbering exhaust in the first quarter of 2038 due to ongoing development.

History

Creation from area code 501

Area code 501, which originally served the entire state of Arkansas since 1947, underwent its first split in 1997 to create area code 870 for most of the state outside the central region, leaving 501 for central Arkansas including Little Rock and Hot Springs. However, rapid population growth in northwestern Arkansas during the 1990s, driven by economic expansion in areas like Fayetteville and Fort Smith, led to increased demand for telephone numbers, projecting exhaustion of 501 by the fourth quarter of 2002. This growth, with the regional population nearly doubling from 1990 to 2010 due to industries such as retail and poultry processing, necessitated further relief planning by the North American Numbering Plan Administrator (NANPA) in the late 1990s. NANPA approved the split of 501 to create 479 in 2001, with the new code officially assigned on , 2001. Permissive dialing for 479 began on January 19, 2002, allowing callers to use either 501 or 479 for numbers in the affected region, while mandatory use of the 10-digit format with 479 for local and long-distance calls within the new area became required on , 2002. The geographic split allocated 479 to the northwestern portion of 501's territory, encompassing regions around Fort Smith, Fayetteville, Springdale, Rogers, Bentonville, and Russellville, while 501 was retained for the central part of the state. This division followed natural boundaries to minimize disruption, with the new code serving areas experiencing the highest growth rates. Initial number allocation under 479 focused on assigning new central office codes (NXX) to unassigned numbers in the northwestern region, ensuring efficient distribution without immediately reassigning existing 501 numbers. Rate centers were established or realigned for key locales such as Fayetteville, Fort Smith, and Rogers to support local calling patterns and service provisioning by telecommunications providers. Existing subscribers retained their 501 prefixes during the transition, but new lines and expansions were issued 479 numbers, providing immediate relief projected to extend availability for several years. To facilitate the changeover, telephone companies including those serving major employers like Wal-Mart, , and the in Fayetteville launched public awareness campaigns through mailings, media announcements, and community outreach starting in late 2001. These efforts emphasized the six-month permissive period for adjustment, resulting in minimal impacts for residents and businesses, though some updates to phone systems, directories, and stationery were required by mid-2002. The transition supported continued in the region without significant service interruptions.

Post-implementation adjustments

Following its activation on January 19, 2002, area code 479 underwent minor boundary realignments to incorporate additional rural telephone exchanges previously served by , as coordinated by the Administrator (NANPA). Rapid population growth in , particularly in Bentonville and Rogers, driven by the expansion of Walmart's headquarters and related , placed significant pressure on available numbers within the 479 area code. Between 2010 and 2020, Benton County (home to Bentonville) saw a 28.1% population increase, while Rogers experienced a 25.5% rise, contributing to heightened demand for central office codes. Despite this surge, which added over 50,000 residents to the region by 2020, no overlays were implemented; instead, efficient number management practices, including thousands-block number pooling introduced by the (FCC) in 2000, helped sustain the single-area-code structure. The Arkansas Public Service Commission (APSC) and NANPA have conducted ongoing administrative updates to support the area's expansion. These updates have been guided by NANPA's annual monitoring of central office code utilization, preventing exhaustion in high-growth zones. The proliferation of Voice over Internet Protocol (VoIP) services and after 2002 has notably influenced number usage in the 479 area code by enabling more flexible assignments and reducing waste from legacy landline systems. VoIP adoption allowed carriers to provision numbers remotely, supporting the region's mobile workforce boom tied to corporate relocations, while portability—mandated by the FCC in 2003—facilitated seamless transitions for users amid economic shifts, thereby extending the code's lifespan without boundary expansions. No significant service disruptions or legal challenges related to these operational changes were reported during the 2000s, reflecting smooth coordination among stakeholders.

Service area

Counties and regions covered

Area code 479 serves the northwestern portion of , encompassing 12 counties in their entirety: Benton, Crawford, Franklin, Johnson, Logan, Madison, Polk, Pope, Scott, Sebastian, Washington, and Yell. It also provides partial coverage to the northern parts of Carroll County, and portions of Conway and counties. The service area is divided into distinct regions, including the metropolitan area primarily in Benton and Washington counties, the region centered on Sebastian and Crawford counties, and the Ozark highlands encompassing Madison and Franklin counties. These regions reflect a mix of urban growth centers, riverine lowlands, and mountainous terrain characteristic of northwest . Geographically, the northern boundary of area code 479 lies near the Missouri state line, while the eastern edge generally follows the I-40 corridor, separating it from the 501 area code in central Arkansas. To the south, coverage extends to Polk and Scott counties, and the western limit borders Oklahoma, excluding eastern Arkansas served by area codes 870 and 327. This configuration was established following the 2002 split from area code 501 to accommodate regional demand.

Cities and communities served

Area code 479 serves a diverse array of urban, suburban, and rural communities across northwestern , with a total estimated of approximately 950,000 residents as of 2025 census projections, reflecting steady growth particularly in the metropolitan area. The region encompasses the bustling metro, anchored by the Fayetteville-Springdale-Rogers , as well as the communities near Fort Smith. Among the major cities, Fayetteville stands out as the largest and most populous, with an estimated 104,000 residents in 2025, serving as a vibrant home to the , which drives its cultural and educational significance through events, research, and a youthful demographic. Springdale, with around 90,000 inhabitants, is a key economic hub tied to the poultry industry, notably as the headquarters of , supporting a diverse workforce and suburban expansion. Rogers, estimated at 77,000 people, functions as a suburban commercial center with retail and logistics growth, benefiting from proximity to major corporations and transportation networks. Bentonville, projected to have 64,000 residents, is renowned as the global headquarters of , fostering innovation in retail, technology, and arts while experiencing rapid population influx. Fort Smith, the region's second-largest city at about 91,000, operates as a community along the Arkansas-Oklahoma line, historically significant for trade, manufacturing, and healthcare services. Other notable communities include Siloam Springs (population ~21,000), a manufacturing and educational near the Oklahoma border with ; Van Buren (~25,000), a historic riverside town emphasizing tourism and logistics; and Russellville (~30,000), an industrial and academic locale anchored by in the River Valley. Smaller towns such as Alma (~6,000) and Greenwood (~9,800) contribute to the suburban fabric, with Alma known for its agricultural heritage and Greenwood for residential growth tied to Fort Smith's metro influence. Beyond these urban and suburban areas, area code 479 extends to rural localities in the Ozark Mountains and , where agricultural communities focused on , ranching, and predominate, alongside forested enclaves supporting and small-scale timber operations. These rural zones, including parts of Madison and Franklin counties, highlight the region's blend of natural beauty and traditional livelihoods, with populations dispersed in towns like Huntsville and Charleston. The overall growth trend, especially in , has seen the metro area add over 13,000 residents annually, driven by corporate relocations and quality-of-life appeals.

Administration and technical details

Numbering plan area designation

Area code 479 serves as a designated Numbering Plan Area (NPA) within the (NANP), administered by the North American Numbering Plan Administrator (NANPA). It was formally established through a geographic split of the existing 501 NPA to accommodate growing demand in northwestern , with central office code (NXX) assignments commencing upon its implementation on January 19, 2002. In the 479 NPA, 10-digit dialing (NPA + NXX + XXXX) is supported for local calls to ensure compatibility with modern systems, though 7-digit dialing remains available for calls within the same local calling area. Intra-area local calls do not use 1+ dialing, which is reserved for long-distance calls. This all-numbering plan adheres to NANP standards, utilizing purely numeric codes without legacy alphanumeric prefixes (e.g., no M-N-X system remnants), ensuring seamless integration with modern telecommunications infrastructure including mobile and internet-based telephony. The NPA encompasses over 100 rate centers, which define geographic boundaries for local calling and billing; prominent examples include FAYETTEVL for Fayetteville and FSMOK for Fort Smith, facilitating precise call routing and tariff application within the region. Oversight of the 479 NPA is provided by the (FCC) for national policy enforcement, for resource allocation and planning, and the Arkansas Public Service Commission (APSC) for state-specific regulation, with no allocation of international access codes (e.g., 011) or special service NPAs (e.g., 8XX toll-free) within this geographic designation.

Current status and projections

As of November 2025, area code 479 supports northwestern with an initial inventory of approximately 7.92 million assignable telephone numbers, based on 792 central office codes each providing 10,000 numbers. Current utilization stands at about 62% of prefixes assigned, equating to roughly 499 out of 800 possible codes, which corresponds to an overall number utilization of around 60% amid steady regional demand. The Administrator () tracks this through semi-annual Numbering Resource Utilization and Forecast (NRUF) reports, ensuring efficient without immediate shortages. NANPA projections indicate no exhaustion before the first quarter of 2038, a timeline adjusted earlier from a previous 2039 forecast due to refined demand modeling as of March 2025 (April 2025 report). This stability contrasts with Arkansas's area code 870, which implemented an overlay with 327 in January 2024 to address prior depletion risks, and 501, which underwent a split creating 479 in 2002. Key drivers of usage include robust population growth in the served region, with adding 13,720 residents in 2024 to reach 605,615, driven by corporate expansions like headquarters in Bentonville and tech developments in Fayetteville. High mobile subscription rates, surpassing 120% in urban zones, further elevate numbering needs as wireless adoption outpaces population. No relief measures, such as splits or overlays, are announced for 479 as of November 2025, though accelerated growth could prompt future planning by .
