Top 10 Industries Using SIC & NAICS Codes for Market Research

Industry Intelligence Center · Updated: November 2025 · Reviewed by: SICCODE Research Team

Market research is only as powerful as the structure behind it. For decades, standardized industry classification systems—SIC (Standard Industrial Classification) and NAICS (North American Industry Classification System)—have empowered organizations, analysts, and investors to organize data, define their markets, and identify new opportunities. Understanding which sectors depend most on these codes reveals how standardized classification transforms data into actionable business insight.

Top 10 SIC and NAICS IndustriesHow Classification Data Fuels Better Market Research

SIC and NAICS codes are more than regulatory tools—they are the backbone of data-driven strategy. By segmenting companies and markets with verified codes, businesses gain:

  • Precise market sizing for product launches and expansion
  • Accurate competitor benchmarking and peer analysis
  • Improved segmentation of prospects by industry, region, and size
  • Reliable inputs for forecasting, trend analysis, and AI modeling
  • Enhanced due diligence for investment, compliance, and credit

For a foundation in classification, see SIC vs NAICS Codes, or browse codes directly in the SIC Directory or NAICS Directory.

1. Manufacturing

Manufacturers are core users of standardized classification. From machinery and electronics to plastics and fabricated metals, SIC and NAICS codes help companies benchmark competitors, track suppliers, and analyze production trends. For instance, NAICS 333999 (Miscellaneous Industrial Machinery Manufacturing) and SIC 3569 (General Industrial Machinery) allow analysts to precisely measure output and employment by sector.

2. Healthcare & Life Sciences

Hospitals, biotech firms, and medical device manufacturers rely on codes such as NAICS 621111 (Offices of Physicians) and 325412 (Pharmaceutical Preparation Manufacturing) to power research and strategic planning. NAICS and SIC classifications segment markets by specialty and region, providing clarity for funding and patient care insight.

3. Software & Technology (SaaS)

Technology companies, SaaS providers, and IT services use industry classification to benchmark innovation, estimate market size, and attract investment. Codes like NAICS 541511 (Custom Computer Programming Services) and SIC 7372 (Prepackaged Software) define high-growth clusters, guiding both analysts and marketers.

4. Energy & Utilities

The energy sector—from renewables to petroleum—relies on classification for investment research and regulatory compliance. NAICS 221118 (Other Electric Power Generation) and SIC 1311 (Crude Petroleum & Natural Gas Extraction) are essential for measuring regional output, environmental impact, and infrastructure growth.

5. Construction

NAICS 236115 (New Single-Family Housing Construction) and SIC 1542 (General Contractors – Nonresidential Buildings) guide construction and engineering companies in benchmarking demand and forecasting project pipelines. Analyzing permit trends by industry code supports forecasting and capital allocation.

6. Retail & E-Commerce

Retailers use classification codes such as NAICS 454110 (Electronic Shopping and Mail-Order Houses) and SIC 5311 (Department Stores) for segmentation and competitor analysis. Accurate classification helps e-commerce leaders plan advertising spend, shelf allocation, and multi-channel growth strategies.

7. Transportation & Logistics

Freight carriers, logistics firms, and warehouse operators depend on codes like NAICS 484121 (General Freight Trucking) and 493110 (General Warehousing and Storage) to analyze trade flow, track supply chain changes, and optimize route networks. Accurate industry data is key to supporting capacity planning and cost control.

8. Financial Services

Banks, insurance agencies, investment funds, and fintech startups depend on classification for compliance, peer analysis, and sector reporting. Codes such as NAICS 522110 (Commercial Banking) and 524210 (Insurance Agencies and Brokerages) underpin risk modeling, product segmentation, and market forecasting.

9. Agriculture & Food Production

Market researchers in agriculture and food rely on codes such as NAICS 311812 (Commercial Bakeries) and 111219 (Other Vegetable and Melon Farming) to monitor production, track supply chains, and analyze consumer demand for both domestic and export markets.

10. Government, Education & Public Administration

Public agencies and academic institutions use industry codes for budgeting, economic impact studies, and workforce development planning. For example, NAICS 923110 (Administration of Education Programs) and 921190 (Other General Government Support) standardize data collection for research and policy grants.

Why Leading Industries Depend on Standardized Codes

Consistent classification ensures comparability—past, present, and future. Without universal codes, macroeconomic forecasting, supply chain analytics, and benchmarking would be impossible at scale. SIC and NAICS codes provide a common language for:

  • Accurate total addressable market (TAM) calculation
  • Customer segmentation and personalized analysis
  • Reliable forecasting, AI models, and predictive analytics
  • Due diligence, compliance, and credit/risk assessment

Mastering code application is now indispensable for every data-driven business and analyst.
