About This Report
Fair Market Value compiles this NAICS 517121 industry report using data from the U.S. Census Bureau[7], the Bureau of Labor Statistics[6], and the Small Business Administration[8]. Our research team analyzes wholesale margin structures, subscriber acquisition costs, and churn rates to build valuation benchmarks for telecom reseller businesses. This report on NAICS 517121 is updated quarterly to reflect competitive pricing shifts and MVNO market dynamics.
Industry Definition & Overview
Telecommunications Resellers (NAICS 517121) encompasses establishments engaged in purchasing access and network capacity from owners and operators of telecommunications networks and reselling wired and wireless services to businesses and households. These resellers do not own or operate transmission facilities. Instead, they contract for wholesale capacity from carriers classified under NAICS 517111 and 517112, then package and market services under their own brands at retail prices.
Mobile virtual network operators (MVNOs) represent the largest and most visible segment within this code. MVNOs purchase bulk wireless airtime and data from major carriers, then sell prepaid and postpaid plans that target budget-conscious consumers, niche communities, or enterprise fleet users. Wired resellers provide long-distance calling, business VoIP, and internet access through leased network capacity. Prepaid calling card providers also fall within this classification.
The reseller model offers lower barriers to entry than facility-based telecom because it eliminates the need for capital-intensive network construction. However, margins depend on wholesale pricing negotiated with underlying carriers, and resellers compete primarily on price, customer service, and niche market positioning. The FCC[4] oversees reseller operations as part of its broader telecommunications regulatory framework. Industry Census Bureau[5] tracks industry revenue, while the Bureau of Labor Statistics[6] reports employment data for the broader telecommunications sector that includes reseller operations.
