How to choose when several codes seem close
NAICS classifies establishments by their primary economic activity, not by LLC structure, business name, or every service they may occasionally provide.
- 01Start with revenue
Identify the activity expected to produce the largest share of receipts.
- 02Read the exclusions
Nearby codes can sound similar. Official exclusions often reveal the correct boundary.
- 03Match the form
Some agencies ask for a broad category while others require the complete six-digit code.
Your code may help agencies, banks, insurers, and researchers understand the business, but it does not replace state or local licensing requirements.
