Questions
How many NAICS 237990 sources sought notices are open?
On October 24, 2026 there were 20 open sources sought notices for NAICS 237990 on SAM.gov, and 330 in the last 12 months. BidFox updates this page every morning.
What is a sources sought notice?
It is a request for information: the agency wants to know which companies can do the work, and whether enough small businesses exist to set the contract aside. It is not a solicitation, so there is no award from it directly.
Should I answer a sources sought notice?
Usually yes, if the work fits you. A short capability statement that answers the questions asked is enough. If two or more capable small businesses respond, the contracting officer often has to set the solicitation aside for small businesses.
How do I get new notices like these by email?
BidFox checks SAM.gov every morning and emails you the new notices that fit your trade and states, sources sought included, with a score and the reason each one fits. It's free for the first 7 days.
