Research the activity. Record the reasoning.
A clearer record behind every classification choice.

Free practical guides, worked examples, and a tool you can use without an account.
Your starting point
Start with the work your business performs.
Business owners, operations teams, market researchers, and government contracting analysts.
Describe the activity
Write what the establishment actually produces or delivers and identify the supporting records.
Compare official definitions
Record candidate codes, versions, cross-references, and facts that distinguish them.
Check the decision context
Keep business classification, solicitation designation, size analysis, and profile updates distinct.
The first useful question
Describe your actual activity before looking for a NAICS code
Build an evidence-based activity statement instead of starting with a favored label.
