NAICS & PSC Code Selection Guide

Wrong NAICS codes do more than hide you from contracting officers — they can disqualify you from a small business set-aside under the wrong size standard. This guide walks the strategic selection process: describe what you actually sell, search for matching codes, then validate them against real federal spending before you commit.

• Why primary versus secondary NAICS matters for size standards and set-asides
• Validation workflow using USASpending.gov and FPDS.gov to test code viability
• How PSCs complement NAICS and where contracting officers actually search
• Reference tables for common technology and services size standards
