This is how RFPRound matches opportunities to you. NAICS codes and states are validated; every other field is a comma-separated list.
A NAICS code is the 6-digit number that classifies what your business does - for example 541512 is Computer Systems Design Services, and 236220 is Commercial Building Construction. If you do not know yours, look it up free at naics.com. Keywords search the notice title and description, so use the words buyers write, like "help desk" or "janitorial". Geography matching uses the solicitation's place of performance where SAM.gov records one.
