What is a NAICS code?

The North American Industry Classification System groups business establishments by their economic activity. Codes run from two-digit sectors to six-digit national industries.

Can I search by business activity?

Yes. Use /naics?q=coffee%20shop for matching industries. Each result shows the name or activity term that matched. When ordinary search finds no results, spelling matching can recover small typing errors and shows the corrected words.

How do I choose between similar industries?

Add deep=true on a paid plan for the definition and exclusions. Compare activities classified elsewhere before choosing a code. The ordinary response includes the immediate parent for context.

Which country and revision are covered?

United States NAICS 2022. Country and year are on the lookup or search envelope. Combined sectors use 31-33, 44-45, and 48-49.

How much does a lookup cost?

Each lookup or search uses one pooled request on every plan. Paid deep adds the definition, child categories, and exclusions, with no separate meter.
