About federal vendor data
Every organization that wants federal contract dollars must register in SAM.gov and receive a Unique Entity ID, and GovChime indexes those registrations alongside the contract history attached to them. Each vendor profile carries the legal business name, CAGE code, physical address, primary and secondary NAICS codes, socioeconomic certifications such as 8(a), HUBZone, WOSB/EDWOSB and SDVOSB, plus the IDV vehicles the company holds and its full FPDS prime award record. Search by NAICS to find competitors bidding your industry, by state to build a local teaming list, or by certification to identify partners who unlock a set-aside you cannot pursue alone. Because registration data and award data are joined on the UEI, you can see not only what a company claims it does but which agencies have actually paid it, how much, and how recently.
