Category codes

Find your trade code

The government tags every job with a 6-digit code. Look yours up so we can match the right work to you.

These are codes — six digits that name your trade.

Levels

  1. 2-digit

    Sector

    9 in this set

    Twenty Census sectors. Three of them are ranges (31–33, 44–45, 48–49).

  2. 3-digit

    Subsector

    18 in this set

    Subsector — production-process grouping inside a sector.

  3. 4-digit

    Industry group

    38 in this set

    Industry group. First four digits a CO still treats as in-family.

  4. 5-digit

    Industry

    59 in this set

    NAICS Industry. Comparable across the U.S., Canada, and Mexico.

  5. 6-digit

    National industry

    70 in this set

    U.S. national industry. The digit a solicitation actually cites.

Census NAICS 2022 has 20 sectors, 96 subsectors, 308 industry groups, 689 industries, and 1012 national industries. GovEdge stores the GovCon working set, not the full 1,012 leaves.

Size — per code, not per firm

SAM asks for receipts and employees once, then applies the SBA table to every NAICS you list. A firm can be small for HVAC and other-than-small for IT.

    Plumbing, Heating, and Air-Conditioning Contractors

    At or under $19.0M receipts — small for 238220.

SBA proposed 2026 grouping

NPRM dated 20 Aug 2026 would collapse ~978 six-digit standards into 338 four- and five-digit groups and raise many IT/services caps. SAM representations still use the 17 Mar 2023 table. Do not certify against the proposed numbers.
