Overview
The residual professional-services code, for scopes that do not fit elsewhere.
In government procurement
541990 is the residual professional, scientific, and technical-services code: it captures specialized professional work that does not fall under a named 5419xx code. It is a supporting code on ITC’s SAM.gov record, useful when a solicitation’s scope spans categories or sits between the defined codes. Contracting officers sometimes index broad or hybrid IT-services requirements here.

UEI PR9KWJPM4JU9 · CAGE 91CE1 · 541990 is a registered NAICS code on ITC’s SAM.gov entity record.
The same capability, commercially
For commercial buyers this code rarely matters by number, but the work it represents (specialized professional and technical services that cross categories) is exactly the kind of hybrid engagement mid-market firms ask for: a single provider who can span advisory, build, and operations rather than three separate vendors. ITC’s four-practice structure is built for that span.
- Federal agencies and SLED (hybrid scopes)
- Prime contractors (multi-discipline subcontract)
- Mid-market and enterprise commercial
- Organizations consolidating multiple vendors

Common questions
When is NAICS 541990 used?
It is the residual professional, scientific, and technical-services code, used for specialized work that does not fall under a named 5419xx code, including broad or hybrid scopes.
Why would ITC bid under a catch-all code?
Some solicitations span categories. ITC’s four-practice structure (advisory, build, managed services, staffing) suits hybrid scopes that a single-discipline firm cannot cover alone.
