NAICS is maintained by the U.S. Census Bureau with Canada and Mexico and revised every five years; the current edition is NAICS 2022. To check exactly what a code includes, search the [official NAICS index](https://www.census.gov/naics/) or read the Census Bureau's [guide to understanding NAICS](https://www.census.gov/programs-surveys/economic-census/year/2022/guidance/understanding-naics.html). Pick a code by what a company mostly does, not by who it sells to.
