Telecom Talk: Navigating NAICS Codes for Telecommunications (2026)

NAICS code telecommunications classification starts with a single parent code, 517, which covers every company whose primary business is transmitting voice, data, text, sound, or video using wired, wireless, satellite, or other network technologies. For IT managers, procurement leads, and telecom analysts, that top-level code is just the entry point. The real value lies in the six-digit subcodes that separate a fiber-optic backbone carrier from a mobile virtual network operator, a satellite broadband provider from a VoIP reseller, or a managed network services firm from a systems integrator. Getting the classification right has direct, measurable consequences: it determines federal contract eligibility, shapes competitive benchmarking, affects SBA small business size standards, and influences how government statistical agencies measure industry health. This guide covers every NAICS code relevant to telecommunications, explains how the hierarchy works, walks through real-world use cases for IT procurement, and tells you exactly which code applies to the vendors and service categories you are evaluating today.

What Is the North American Industry Classification System and Why Does It Matter to Telecom?

The North American Industry Classification System, universally known as NAICS (pronounced “nakes”), is the standard framework the federal governments of the United States, Canada, and Mexico use to classify business establishments by their primary economic activity. The U.S. Census Bureau, the U.S. Bureau of Labor Statistics, and Statistics Canada all rely on NAICS codes to produce the economic data that flows into GDP calculations, employment reports, market sizing studies, and regulatory filings.

NAICS replaced the older Standard Industrial Classification (SIC) system in 1997 specifically because SIC was built for a manufacturing economy and could not adequately represent a service economy driven by information technology. Telecommunications was one of the sectors most poorly served by SIC. The old SIC code 4813 lumped telephone communications companies together in ways that made no meaningful distinction between a long-distance reseller and a Bell Operating Company. NAICS fixed that by creating a dedicated sector for information industries, placing telecommunications inside it, and building a granular six-level hierarchy.

The hierarchy works like this: every NAICS code begins with a two-digit sector, expands to a three-digit subsector, then a four-digit industry group, a five-digit industry, and finally a six-digit national industry. For telecommunications, the path looks like this: Sector 51 (Information), Subsector 517 (Telecommunications), and then increasingly specific codes below that. The system is updated every five years. The 2017 edition, the 2022 edition, and any changes introduced for the 2027 cycle all matter to companies that maintain active registrations in SAM.gov or respond to federal solicitations.

For IT managers and procurement leads, NAICS codes are not abstract taxonomy. They show up on every federal contract vehicle, every SBA certification, and every vendor capability statement. When you issue an RFP through a GSA schedule or a SEWP contract, the NAICS code you list in the solicitation determines which vendors are eligible to bid. When you are benchmarking a vendor’s pricing against market data from IBISWorld, Gartner, or the FCC’s Communications Marketplace Report, those datasets are organized by NAICS code. Understanding the classification system helps you ask better questions, find better comparisons, and make better purchasing decisions. You can read more about how regulatory and standards frameworks shape procurement decisions in our coverage of ANSI/TIA-606 telecommunications infrastructure labeling guidelines.

The Complete NAICS 517 Telecommunications Hierarchy

NAICS 517 is the subsector that contains every pure-play telecommunications classification. Below is the full hierarchy as it stands under the 2022 NAICS revision, which is the version currently in use for federal procurement and Census Bureau reporting.

NAICS Code	Title	SBA Small Business Size Standard (Annual Receipts)	Typical Company Examples
517	Telecommunications (Subsector)	Varies by 6-digit code	All telecom companies
5171	Wired and Wireless Telecommunications (except Satellite)	Varies	Carriers, ISPs, MVNOs
517111	Wired Telecommunications Carriers	$40 million	AT&T, Lumen, Consolidated Communications, CLECs
517112	Wireless Telecommunications Carriers (except Satellite)	1,500 employees	Verizon Wireless, T-Mobile, US Cellular, MVNOs
5174	Satellite Telecommunications	Varies	Satellite carriers and resellers
517410	Satellite Telecommunications	$40 million	Starlink (SpaceX), Viasat, HughesNet, Intelsat
5178	All Other Telecommunications	Varies	Resellers, VoIP, specialty providers
517919	All Other Telecommunications	$40 million	VoIP resellers, paging, two-way radio, internet resellers

One important note for procurement teams: the SBA size standards listed above are used to determine whether a vendor qualifies as a small business for federal contracting purposes. A company with $39 million in annual receipts filing under NAICS 517111 qualifies as a small business. The same company filing under 517112 must meet an employee count threshold instead. This distinction affects set-aside eligibility and should factor into your vendor qualification process.

What Changed in the 2022 NAICS Revision

The 2022 revision was the most significant update to NAICS telecommunications codes in over a decade. The most impactful change was the consolidation of the old 517311 (Wired Telecommunications Carriers) and 517312 (Wireless Telecommunications Carriers except Satellite) into the new 517111 and 517112 respectively. The four-digit grouping changed from 5173 to 5171. If you are working with legacy government databases, market research reports published before 2022, or older contract vehicle registrations, you will encounter the old 5173x codes. They map directly to their 5171x successors, but the change creates confusion when comparing historical data across revision years. Always confirm which NAICS edition a data source is using before drawing cross-year comparisons.

Deep Dive: NAICS 517111 Wired Telecommunications Carriers

NAICS 517111 covers companies that operate and maintain the physical wireline infrastructure that carries voice, data, and video signals. This includes incumbent local exchange carriers (ILECs) like AT&T and Verizon’s wireline divisions, competitive local exchange carriers (CLECs) like Windstream and TeleCove, cable companies operating as telephone providers, and fiber-to-the-premise operators like Google Fiber and Ziply Fiber.

The defining characteristic of a 517111 company is network ownership. These are the businesses that own or lease the conduit, the fiber strands, the copper pairs, the DSLAMs, the CMTS equipment, and the central office switching infrastructure. They are facilities-based carriers. That distinction matters enormously to enterprise IT managers because a facilities-based carrier has direct control over service level agreements, network performance parameters, and trouble resolution timelines in ways that resellers do not.

What Wired Carriers Sell to Enterprise Customers

Under 517111, the product portfolio relevant to corporate IT includes dedicated internet access (DIA) circuits at speeds ranging from 10 Mbps to 100 Gbps, MPLS wide area networks, Ethernet private line services, dark fiber leases, hosted PBX delivered over owned infrastructure, and traditional TDM voice trunks (though TDM is in long-term decline as carriers sunset copper networks). Enterprise pricing for DIA from a Tier 1 wired carrier typically starts around $300 to $500 per month for a 100 Mbps fiber circuit in a metro market and scales to $3,000 to $8,000 per month for a 1 Gbps dedicated circuit in a secondary market where fiber density is lower.

IT managers evaluating wired carriers should scrutinize the carrier’s last-mile infrastructure map before signing a multi-year contract. A carrier may be 517111-classified but rely on a third-party CLEC for the final mile to your building, which introduces a second support tier and complicates escalation paths when an outage occurs.

Deep Dive: NAICS 517112 Wireless Telecommunications Carriers

NAICS 517112 covers companies that provide wireless telecommunications services without using satellite technology. The major national operators in this category are T-Mobile, Verizon Wireless, and AT&T Mobility. Regional carriers include US Cellular and C Spire. Mobile virtual network operators (MVNOs) that lease capacity from the nationals and resell it under their own brand also fall here, though some MVNOs are classified under 517919 depending on their primary activity and the degree to which they own infrastructure.

The 517112 category is where 5G network buildout is happening. As of 2026, T-Mobile has the widest 5G standalone core deployment, covering approximately 300 million people with its mid-band spectrum (primarily 2.5 GHz inherited from the Sprint merger). Verizon’s C-band deployment is accelerating after a slow start, and AT&T’s FirstNet priority network for public safety is a meaningful differentiator for state and local government IT procurement.

Enterprise Wireless Procurement Considerations

For IT managers managing mobile device fleets, the 517112 classification is the bucket you are shopping in when you negotiate enterprise mobility agreements. Key factors to evaluate include:

• Network coverage maps verified against your specific office locations and employee travel corridors, not national average coverage statistics
• Enterprise mobility management (EMM) integration support for platforms like Microsoft Intune, VMware Workspace ONE, and Jamf
• Dedicated account management and escalation paths, which are typically only available on enterprise agreements with $50,000 or more in annual recurring spend
• International roaming agreements and per-country rates, which vary significantly between carriers for the same destination
• 5G SA (standalone) versus 5G NSA (non-standalone) network availability in your priority markets, because only SA delivers the latency improvements relevant to real-time applications
• Device procurement programs, including device-as-a-service financing structures that shift hardware capex to opex

Deep Dive: NAICS 517410 Satellite Telecommunications

NAICS 517410 covers companies that provide telecommunications services via satellite. This code has gained renewed relevance for enterprise IT procurement because of the emergence of low-earth orbit (LEO) satellite broadband as a practical option for branch offices, construction sites, maritime operations, and government field deployments.

The traditional players in 517410 include Viasat and HughesNet, both of which operate geostationary (GEO) satellites at approximately 35,786 kilometers above Earth. GEO satellite broadband delivers latency in the range of 500 to 700 milliseconds round-trip, which makes it unsuitable for real-time voice, video conferencing, or latency-sensitive cloud applications without significant workarounds.

SpaceX Starlink, which began commercial operations in 2021 and launched its Business tier in 2022, operates a LEO constellation at altitudes between 340 and 1,200 kilometers. This dramatically reduces latency to 20 to 40 milliseconds under typical conditions, bringing satellite broadband into a performance range that is genuinely usable for UCaaS, VoIP, and cloud-based ERP access. Starlink Business pricing as of 2026 starts at $250 per month for service plus a $2,500 hardware kit for the flat high-performance antenna. Amazon Kuiper, expected to reach commercial availability in 2026 and 2026, will introduce additional competition in the LEO segment.

For IT managers in industries like energy, agriculture, transportation, or government, 517410-classified vendors deserve serious consideration in site connectivity planning. The latency and throughput improvements in LEO satellite have closed the gap with terrestrial alternatives enough that satellite is now a viable primary circuit option in locations where fiber or fixed wireless cannot reach. When evaluating CCaaS platforms for distributed workforces that may rely on satellite connectivity, our guide to navigating the CCaaS landscape covers how cloud contact center platforms handle variable-latency connections.

Deep Dive: NAICS 517919 All Other Telecommunications

NAICS 517919 is the residual classification for telecommunications activities that do not fit within the more specific 517111, 517112, or 517410 codes. In practice, this is a critically important code for IT procurement because it captures several vendor categories that are highly relevant to enterprise technology buyers.

VoIP Providers and Internet Telephony

Voice over Internet Protocol providers that resell or aggregate capacity from underlying carriers rather than owning physical network infrastructure typically fall under 517919. This includes many of the UCaaS providers that IT managers evaluate for business phone system replacements: companies like RingCentral, Vonage (now part of Ericsson), 8×8, and smaller regional hosted VoIP providers. The SBA small business size standard of $40 million in annual receipts under this code means that many mid-market UCaaS providers qualify as small businesses for federal set-aside purposes.

Paging and Two-Way Radio

Commercial paging carriers, land mobile radio operators, and specialized two-way radio service providers are also classified here. This matters for industries like healthcare (where paging remains in active use for clinical workflows), public safety, and manufacturing environments where push-to-talk radio is a primary communication tool.

Internet Access Resellers

Companies that purchase wholesale internet access from facilities-based carriers and resell it under their own brand, without owning the underlying network infrastructure, are typically classified under 517919. This is a common business model among regional managed service providers and IT service companies that bundle connectivity with network management services.

NAICS Codes Adjacent to Telecommunications That IT Managers Need to Know

Several NAICS codes outside the 517 subsector are frequently relevant to enterprise telecom procurement decisions. Knowing these helps you correctly categorize vendors who blend telecommunications with technology services, and it helps you interpret market research data that may slice the industry differently than you expect.

NAICS Code	Title	Why It Matters to Telecom Procurement
518210	Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services	Cloud PBX and UCaaS platforms hosted in third-party data centers often classify here rather than under 517919
541519	Other Computer Related Services	Managed network services firms, SD-WAN integrators, and network security providers often use this code
334220	Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing	Covers manufacturers of wireless access points, small cells, and radio equipment
334210	Telephone Apparatus Manufacturing	IP phone manufacturers, conference room endpoint makers
561422	Telemarketing Bureaus and Other Contact Centers	Relevant when procuring BPO contact center services alongside CCaaS technology
541512	Computer Systems Design Services	Systems integrators who design and implement enterprise network and voice infrastructure

The blurring of lines between 517919 and 518210 is particularly relevant right now because of how major UCaaS vendors classify their primary business activity. A company like RingCentral derives its revenue from software subscriptions delivered over cloud infrastructure it does not own. Depending on how its accountants weigh primary business activity, it may register under 518210 rather than 517919. When you are searching a procurement database by NAICS code to find eligible UCaaS vendors, searching only 517919 will miss vendors correctly classified under 518210. Smart procurement teams search both codes.

Understanding how these adjacent classifications interact with broader industry strategy matters for long-range planning as well. For context on where UCaaS fits in the broader technology transformation of enterprise communication, our analysis of the telecommunications board’s role in digital innovation covers governance frameworks relevant to IT leaders managing these transitions.

How NAICS Codes Are Used in Federal Telecom Procurement

Federal telecom procurement is one of the most structured purchasing environments in the world, and NAICS codes are the load-bearing architecture that holds it together. Every solicitation published on SAM.gov requires a primary NAICS code. Every vendor registered in SAM.gov must declare its NAICS codes. Contract vehicles like the GSA Multiple Award Schedule (MAS), SEWP V, ITES-3S, and EIS (Enterprise Infrastructure Solutions) are all organized around NAICS codes. If a vendor’s registered NAICS codes do not match the code on your solicitation, that vendor is ineligible to receive an award under that action without an exception or modification.

EIS and the Telecom-Specific Contract Vehicle

The GSA Enterprise Infrastructure Solutions (EIS) contract, which replaced Networx in 2017 and has been the primary vehicle for federal agency telecommunications procurement since then, covers services spanning NAICS 517111, 517112, 517410, and 517919. EIS has a ceiling of approximately $50 billion over its 15-year ordering period. Agencies use EIS task orders to procure DIA, MPLS, voice services, mobility, and managed network services. When a federal agency issues an EIS task order, the NAICS codes attached to that order determine which EIS awardees can compete for the work.

SBA Small Business Set-Asides and NAICS Code Selection

For small business vendors in the telecom space, the choice of primary NAICS code has direct revenue implications. Under NAICS 517111, the size standard is $40 million in average annual receipts, meaning a company with $38 million in revenue qualifies as small and can compete for 8(a), WOSB, SDVOSB, and other set-aside contract actions. Under NAICS 517112, the size standard is 1,500 employees, which is dramatically more permissive and allows much larger companies to claim small business status. A company with 1,400 employees and $500 million in revenue qualifies as a small business under 517112. This is not an academic point: it directly affects the competitive set you will encounter when evaluating bids on a small business set-aside telecom solicitation.

Practical Steps for Procurement Teams

1. Identify the primary service being procured and match it to the most specific NAICS code that accurately describes that service, not the broader parent code.
2. Verify that your target vendors have the relevant NAICS codes active in their SAM.gov registrations before issuing the solicitation.
3. For acquisitions that blend telecommunications with IT services (such as an SD-WAN managed service), consult with your contracting officer about whether 517111, 541519, or a dual-code approach is most appropriate.
4. When using market research tools like USASpending.gov or FPDS-NG to benchmark pricing, filter by the six-digit NAICS code rather than the subsector to ensure you are comparing similar scopes of work.
5. For awards under the MAS schedule, confirm that the Special Item Number (SIN) aligns with the NAICS code, as some telecom services are sold under SIN 517910 (telecom) while others appear under technology category SINs.

NAICS Codes and Industry Research: Using Classification Data for Strategic Decisions

Beyond procurement, NAICS codes are the organizing principle for virtually every structured dataset about the telecommunications industry. The U.S. Census Bureau’s Annual Business Survey, the FCC’s Communications Marketplace Report, the BLS Quarterly Census of Employment and Wages, and commercial market research from IBISWorld, Vertical IQ, and First Research all segment their data using NAICS codes. Understanding which code aligns with the market segment you are analyzing is essential for drawing meaningful conclusions from these sources.

For instance, if you are evaluating whether to add a second wireless carrier to your corporate mobile program, pulling BLS wage data for NAICS 517112 tells you something about labor costs and employment trends in that carrier segment, which feeds into an assessment of service quality sustainability. If you are trying to understand competitive dynamics in the fiber ISP market before negotiating a large DIA renewal, IBISWorld’s NAICS 517111 report gives you revenue concentration data, margin trends, and the top 20 competitors by market share in a format that is directly comparable to financial data your vendor may disclose in RFP responses.

The FCC’s Communications Marketplace Report, published annually under Section 13 of the Communications Act, uses NAICS codes to organize its analysis of competition and market performance across fixed broadband, mobile broadband, voice, and video distribution. This is a free, authoritative source that procurement leads often overlook. The 2023 report, for example, contains granular data on average broadband speeds by technology type (which maps to 517111 for fiber and cable, 517112 for fixed wireless, 517410 for satellite), which gives enterprise buyers a defensible benchmark when evaluating whether a carrier’s promised throughput is consistent with its peers.

Telecom marketing and go-to-market strategy also intersects with NAICS classification. Vendors building targeted campaigns for enterprise buyers organize their prospect databases by NAICS code, which means understanding your own organization’s classification helps predict what vendors will approach you with and on what terms. Our breakdown of essential marketing strategy for the telecom industry covers how carriers and service providers use industry classification data to prioritize enterprise accounts.

How to Determine the Correct NAICS Code for Your Telecom Business or Vendor

Use the following decision framework to select the right six-digit code within 517:

• Does the company own or operate physical wireline network infrastructure (fiber, copper, coax, DSL)? If yes, the primary code is likely 517111.
• Does the company provide cellular or mobile broadband services using licensed spectrum and radio access network equipment? If yes, the primary code is likely 517112.
• Does the company provide communication services via satellite, including broadband, voice, or data relay? If yes, the primary code is 517410.
• Does the company resell telecommunications services purchased from underlying carriers without owning the network infrastructure? The likely code is 517919, unless the primary activity is software or data processing, in which case 518210 may be more accurate.
• Does the company provide specialized telecommunications services like paging, private radio dispatch, or VoIP resale? The code is 517919.
• Does the company design, install, or manage telecom networks as a service rather than operating them as a carrier?
