How North American Industry Classification System works in supplier diversity
NAICS codes are 6-digit codes that identify a business's primary industry. They replace the older SIC code system and are used to determine small business size standards. The first two digits represent the sector, and subsequent digits provide increasing specificity. Choosing the right NAICS code affects which contracts you can compete for as a small business.
