Established in 1997, the North American Industry Classification System (NAICS) is a collaborative effort by the United States, Canada, and Mexico to create a unified framework for classifying business establishments. This system facilitates the collection, analysis, and publication of statistical data related to the North American economy, ensuring consistency and comparability across various industries. Federal statistical agencies, as well as businesses and researchers, utilize NAICS to monitor economic activities, analyze industry trends, and make informed decisions.
Structure of NAICS Codes
NAICS employs a hierarchical structure, using a six-digit coding system to represent different levels of industry classification:
- Two-Digit Codes: Represent the 20 broad economic sectors.
- Three-Digit Codes: Subsectors within these sectors.
- Four-Digit Codes: Industry groups.
- Five-Digit Codes: Specific industries.
- Six-Digit Codes: National industries, allowing for country-specific details.
This structured approach ensures a detailed and organized classification of industries, accommodating the diverse nature of economic activities.
E-Commerce and NAICS Code 454110
Within the NAICS framework, e-commerce businesses are primarily classified under:
- NAICS Code 454110: “Electronic Shopping and Mail-Order Houses.”
This code encompasses establishments primarily engaged in retailing all types of merchandise using non-store means, such as catalogs, toll-free telephone numbers, or electronic media like interactive television or the Internet. In essence, it includes businesses that sell products or services online, making it the standard classification for e-commerce retailers. citeturn0search1

Recent Revisions and Updates to NAICS Codes

The Role of NAICS in Economic Analysis and Policy Making
Accurate NAICS classification extends beyond individual businesses; it plays a pivotal role in shaping economic policies and understanding market dynamics:
- Data Collection: Government agencies rely on NAICS codes to collect data on employment, revenue, and other economic indicators.
