NAICS Code Definition & Meaning

NAICS Code

A NAICS code (North American Industry Classification System code) is a standardized six-digit identifier used to classify businesses by industry in Canada, the United States, and Mexico. It helps government agencies, researchers, and marketers categorize and analyze business activities. Whether you’re searching for a business NAICS code or a specific NAICS code for business consulting, this classification plays a key role in market segmentation and lead generation.

Importance of NAICS Code in B2B Sales

Understanding a company’s NAICS code can unlock valuable insights for B2B sales teams. These codes allow sales professionals to identify industry segments, refine targeting strategies, and build tailored outreach campaigns. For example, if you’re selling to consulting firms, knowing the business consulting NAICS code helps filter the right prospects efficiently. NAICS business codes also improve the accuracy of market research and competitive analysis, which are critical for demand generation and account-based marketing strategies.

Common Challenges with NAICS Code

Inaccurate or Outdated Codes: Some businesses may have incorrect or old NAICS classifications, especially if they operate in multiple industries.
Multi-Sector Business Classification: Companies like consulting firms may span several NAICS categories, making it hard to assign a single accurate code.
Inconsistent Self-Reporting: Organizations may list different NAICS codes across various platforms, causing data reliability issues.
Emerging Industry Mapping Issues: New or niche industries may not have a direct NAICS code due to delayed updates in the system.
Use of Closest Fit: When no perfect match exists, select the nearest appropriate code and supplement with internal custom tags.
Data Verification Needs: Cross-reference commercial databases with sources like Statistics Canada or the U.S. Census Bureau to ensure accuracy.

FAQs: NAICS Code

1

How do I find my NAICS code?

You can find your NAICS code through the official NAICS website or by checking your business registration documents. If you’re in the U.S. or Canada, government databases let you search by keyword or browse by sector. Businesses often self-select the code that best represents their primary activities. For example, a marketing consultancy might use the business consulting NAICS code 541611. If you’re unsure which business NAICS code to use, start with your core offering and compare it against NAICS definitions for a match.

2

Is NAICS the same as EIN?

No, a NAICS code is not the same as an EIN (Employer Identification Number). Your EIN is a unique tax ID assigned by the IRS (or CRA in Canada), while your NAICS code categorizes your business by industry. Think of it this way: your EIN identifies your company for tax purposes, while your business code NAICS helps classify what your company does. Both are important for different reasons, especially in government filings, business credit applications, and sales targeting.

What is the NAICS code for business to business?

There isn’t a single NAICS code for all B2B companies because B2B refers to the business model, not a specific industry. Instead, B2B companies are classified based on the nature of their services or products. For instance, a B2B consulting firm might use NAICS code 541611 (Administrative Management and General Management Consulting Services), while a B2B tech provider might fall under 541512 (Computer Systems Design Services). To identify the right NAICS code for your B2B company, match your services with the closest industry description in the NAICS directory.
