What if I work under multiple NAICS codes?
You may list multiple NAICS codes in SAM.gov, but for each contract, you must qualify as small under the specific NAICS code designated by the contracting officer. Your size is measured against the size standard for the contract's NAICS code, not your primary code. If you exceed the size standard for a particular NAICS code, you cannot bid as a small business on contracts under that code, even if you are small under others.
