As of April 4, 2022, the federal government has transitioned away from the use of DUNS to a SAM.gov-generated Unique Entity ID. A SAM number is needed for certain types of sub-awards in order to meet federal government reporting requirements.

We appreciate your consideration when registering with SAM and ask that your organization opt in to the search capability within the SAM database. This will save your organization time because we can verify company information and view your organization’s SAM registration status without having to ask you for additional proof.

The North American Industry Classification System (NAICS, pronounced Nakes) is the standard used by federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. This standard allows for a high level of comparability in business statistics among the North American countries.

NAICS replaced the Standard Industrial Classification (SIC) System in 1997.

The U.S. Small Business Administration has a table of small business size standards to assist small businesses in assessing their business size.

Additional information, including a NAICS Manual and FAQs, can be found on the U.S. Census Bureau website.

How to Determine Your Organization’s NAICS Code

Visit the U.S. Census Bureau website. In the “NAICS Search” area on the left, enter a keyword that describes your kind of business. A list of business activities with keywords and their corresponding NAICS codes will appear. Choose the one that most closely represents your primary business function.
