Frequently asked questions

What is NAICS 621111?

NAICS 621111 is the federal industry code for Offices of Physicians (except Mental Health Specialists). The Census Bureau maintains the NAICS taxonomy; federal contracting officers use it to classify solicitations and confirm bidder eligibility.

How do I bid on federal contracts as a small business in NAICS 621111?

Do I need a SAM.gov registration to bid?

Yes — every federal contract award above the micro-purchase threshold requires the vendor to have an active SAM.gov registration with a Unique Entity Identifier (UEI) and the relevant NAICS codes listed on the registration.
