Understanding NAICS Codes for Ecommerce in 2025
The North American Industry Classification System undergoes updates every five years to reflect economic changes. The most recent update in 2022 brought substantial changes to how ecommerce businesses are classified.
One of the most notable changes affects the Retail Trade sector, which now focuses on product types rather than selling methods. Furthermore, the traditional separation between brick-and-mortar stores and online retail has been eliminated. This means that hardware sales previously classified under Electronic Shopping and Mail-Order Houses (454110) are now grouped with Hardware Retailers (444140).
NAICS employs a structured six-digit format that provides detailed industry classification. The first two digits indicate the sector, while subsequent digits refine the classification into subsectors, industry groups, and specific industries. Additionally, federal agencies use these codes to collect and analyze statistical data related to the U.S. business economy.
The system’s importance extends beyond classification. Essentially, businesses rely on NAICS codes for:
Market research and competitive analysis
Government contract applications
Tax incentive qualification
Strategic decision-making based on reliable data
The Census Bureau has begun implementing these updated classifications in the 2022 Economic Census, with all remaining economic programs planned to transition by 2027. Consequently, businesses must stay informed about these changes to maintain accurate industry classification and access to relevant benefits.
How to Determine Your Ecommerce NAICS Code

Finding the right NAICS code for your ecommerce business follows a straightforward process. Since NAICS is a self-assigned system, you select the code that best matches your primary business activities.
Here’s how to determine your NAICS code:
Identify Your Primary Activity: Analyze your main revenue-generating activities. For online retailers selling products directly to customers through websites or platforms like Amazon, the primary NAICS code is 454110.
Use the NAICS Search Tools: Enter keywords related to your business activity on naics.com. For instance, if you run a dropshipping business or operate through Shopify, your classification still falls under 454110.
Review Code Descriptions: Read the complete industry description to ensure it aligns with your business model. Notably, code 454110 covers all types of merchandise sold online, regardless of the products.
Consider Multiple Codes: If your business generates revenue through various channels, you might need additional codes. Nevertheless, for purely online retail operations, 454110 remains your primary classification.
Moreover, the Internal Revenue Service uses your selected NAICS code to evaluate if your business tax returns align with industry standards. Specifically, they compare your tax deductions with similar businesses in your sector, making accurate classification crucial for avoiding potential audits.
Primarily, remember that the NAICS code 454110 applies to all online stores, regardless of the products sold. This classification encompasses electronic shopping, mail-order houses, and internet retail sites.
Special Considerations for Different Business Models

Different ecommerce business models require unique approaches to NAICS classification. Primarily, businesses selling products through online marketplaces like Amazon, eBay, and Wayfair fall under the classification code 454110.
For Amazon FBA sellers, accurate NAICS classification holds particular importance. These sellers benefit from using code 454110 as it aligns with their business model of outsourcing logistics, storage, and shipping operations. Accordingly, this classification helps FBA sellers optimize their visibility and comply with platform regulations.
When operating multiple business models simultaneously, companies might need to consider additional classifications. Here are key factors that influence NAICS code selection:
Business Structure: Pure online retailers versus hybrid models with physical locations
Revenue Sources: Primary income streams from different business activities
Distribution Methods: Direct selling, dropshipping, or marketplace platforms
Product Categories: Specialized retail segments within ecommerce
Alternatively, businesses involved in electronic auctions should note that NAICS 454210 applies to their operations. Meanwhile, companies engaging in direct selling through methods like party plan merchandising or portable stalls fall under NAICS 454390.
Presently, the classification system accommodates various retail activities, enabling businesses to track sector-specific trends and analyze competition effectively. This flexibility allows companies to adapt their strategies based on market insights while maintaining proper industry classification.
