Questions people ask

What is Rees Scientific Corporation's UEI?

NCRKL9YLY2X4. The Unique Entity ID is the 12-character number SAM.gov assigns to every company that registers to do business with the federal government. It replaced the DUNS number in 2022.

How much has Rees Scientific Corporation won in federal contracts?

$7.9M obligated across 24 awards in Captivaq's records, most of it from National Institutes of Health. That covers contracts of $1M or more active since October 2023, so the full history is larger.

Which Rees Scientific Corporation contracts end soon?

12 awards end in the next 18 months, listed on this page. Expiring contracts are often recompeted, which is the opening for a competitor or a teaming partner.

Figures come from federal award records published on USAspending.gov: contracts of $1M or more active since October 2023, plus smaller awards tied to open opportunities. They are not a complete contract history; each award above links to its official record.
