NAICS 22 — Utilities

Understanding Sector 22

NAICS sector 22 is one of 20 industry sectors defined by the North American Industry Classification System. The federal government uses these codes to classify contract requirements, determine small business eligibility, and track procurement spending across industries. When a federal agency issues a solicitation, they assign a NAICS code that best describes the principal purpose of the acquisition — this determines the applicable size standard for small business participation.
