The 30 Most Valuable NAICS Codes for Government Contractors in 2026

Your NAICS code selection determines which federal opportunities you're eligible to compete for. Choose too broadly and you'll miss the ones that matter. Choose too narrowly and you'll have a thin pipeline.

Here are the codes with the highest federal spend and most 8(a) set-aside activity.

Top Codes by Federal Spend

NAICS 541330 — Engineering Services ($18B+ annual federal spend) Dominant in DoD, Corps of Engineers, and infrastructure agencies. Heavy 8(a) set-aside activity.

NAICS 541512 — Computer Systems Design ($25B+ annual federal spend) The largest single NAICS category for federal IT services. DISA, Army, and civilian agencies all post heavily here.

NAICS 541611 — Management Consulting ($8B+ annual federal spend) Strong at DHHS, State Department, and USAID. Many sole-source opportunities for ANCs.

NAICS 561210 — Facilities Support ($12B+ annual federal spend) Base operations, maintenance, and support. Consistent recompetes with predictable award timing.

NAICS 237310 — Highway/Bridge Construction ($15B+ annual federal spend) FHWA and state DOTs. Many 8(a) set-asides in rural and remote areas — natural fit for ANCs.

How to Select Your Codes

1. Start with what you actually do (don't overreach)
2. Add adjacent codes where you have teaming partners
3. Check federal spend data on USAspending.gov for each code
4. Verify set-aside activity — some codes are rarely set aside
5. Monitor for 6-12 months before committing your BD resources
