SDB is an ownership/diversity self-certification recognized by the Small Business Association (SBA) of the United States government.
This certification is intended for organizations that are owned and operated at least 51% by one or more disadvantaged persons. The disadvantaged person must be both socially and economically disadvantaged and the organization as a whole must still be small by SBA standards to be eligible as an SDB.
Self-Representation or Self-Certification to SDB is accomplished by registering with the U.S. Government’s System for Award Management (SAM) database. The registration requires users to enter information related to the company’s size and industry (by NAICS code) which SAM will use to determine if the organization is eligible to self-certify.
