The North American Industry Classification System (NAICS) provides a standardized method for federal statistical agencies to classify business establishments by industry. This comprehensive system facilitates the collection, analysis, and publication of economic data across the United States, Canada, and Mexico. Understanding your company’s NAICS code is a foundational step in formalizing business operations and interacting with various government entities. Identifying the correct code grants access to industry-specific information.
Why NAICS Codes Are Necessary
Possessing the accurate NAICS code is foundational for several mandatory reporting and strategic planning activities. Businesses are commonly required to report this code for federal and state tax purposes, ensuring their financial data is correctly categorized alongside industry peers. This classification is used by statistical agencies to generate industry-specific economic reports, providing a clear picture of performance and trends within your specific sector.
The code also plays a significant role in accessing government opportunities, such as eligibility for certain Small Business Administration (SBA) loan programs and federal contracting set-asides. Government agencies utilize the six-digit code to define the scope of their programs and verify that applicants meet the size and industry requirements for participation. Furthermore, the code is valuable for internal market research, allowing a business to effectively benchmark its financial performance, growth metrics, and compensation structures against others operating in the same industry classification.
Locating Your Code Using the Official Census Bureau Site
The U.S. Census Bureau maintains the official online portal for the North American Industry Classification System and should be the first resource for code identification. Users can reliably locate their appropriate code by utilizing one of two primary search methods available on the site’s interface.
The simplest approach involves using the keyword search function. Entering a descriptive term like “Specialty Food Store” or “Residential Remodeling” will yield a list of relevant NAICS codes and their associated descriptions. This keyword search often returns multiple potential codes, requiring the user to carefully examine the full industry description to determine the proper fit. For example, a search for “bakery” might return codes for a retail bakery, a commercial bakery, or a frozen bakery product manufacturer, each with distinct classification numbers. The search results provide the title and a detailed scope for each code, which is the most instructive part of the process.
The second, more precise method involves navigating the system’s hierarchical structure. This structure begins with 20 broad 2-digit sectors, such as Manufacturing or Information. Users select an initial sector and then progressively drill down through the 3- and 4-digit subsectors to narrow the scope of the industry. This method is particularly helpful when a business activity is difficult to describe with a single keyword.
The final step in this process is identifying the 6-digit code, which represents the most granular industry classification available and is the number generally required for official documentation and reporting. The 5-digit code is the national industry level, while the final 6th digit often reflects a further specialization within the North American system. Users should verify that the selected 6-digit classification accurately encompasses their primary business activities before finalizing their choice.
Using Alternative Government and Business Resources
While the Census Bureau provides the authoritative classification system, other government and business resources can be used to verify or quickly look up an existing code. The Small Business Administration (SBA) website is a frequent destination, particularly for businesses seeking federal contracts or loans. The SBA utilizes NAICS codes to determine eligibility for various programs, and their size standards table is a useful tool for cross-referencing a code with specific revenue or employee limits.
A business may already have its code recorded on existing administrative documents, simplifying the verification process. Many federal tax forms, such as the Schedule C (Form 1040) for sole proprietorships or the various corporate income tax returns, require the business to enter its primary NAICS code. Reviewing previously filed tax documents can confirm the code that has already been reported to the Internal Revenue Service. State business registration forms and annual reports may also require or list the NAICS classification. Using these secondary sources is a reliable way to ensure consistency across all governmental filings. These resources function best as verification tools.
Selecting the Primary Code for Complex Businesses
Many modern businesses generate revenue from activities that span multiple industry classifications, requiring them to determine a single, primary NAICS code. For instance, a company might operate a retail store while also providing professional consulting services, each falling under a different 6-digit code. The determination rule for these complex operations centers on the revenue generated by each activity.
The business must identify the industry activity that contributed the largest percentage of its total revenue during the preceding calendar year. This activity is designated as the establishment’s primary classification. The focus is exclusively on the financial weight of the operation, rather than the number of employees or physical space dedicated to the activity. If the revenue contributions fluctuate significantly year-to-year, the business should use the activity expected to generate the largest share of revenue in the current reporting period.
