Searching codes
NAICS Explorer (/vendor/naics) covers NAICS 2022: 20 sectors and 1,012 six-digit codes from the U.S. Census Bureau. Search a code or a word (541512, software, aircraft parts), or open a sector in the tree. When your spelling is close, the page shows the corrected search and says what you typed. Your own codes sit in a strip at the top, primary first, with the count of open notices under each.
What a code page shows
The definition where the catalog has one (some codes have a title only, and the page says so), related product and service codes and cross references, and the SBA size standard from 13 CFR 121.201 with its exceptions and footnotes. The Market snapshot shows awards on file by fiscal year, top agencies by awards on file, and the set-aside mix of open notices, with an as-of date. Every number is a count of rows the platform holds, never a federal total.
Actions
Search open opportunities with the code, Set an alert (a saved search on the code), or add the code to your company profile, make it primary, or remove it. A preview shows what each change does to your fit score and tabs, with an undo. A code unrelated to your profile codes earns no NAICS credit in the fit score, and the page says so.
PSC reference
PSC Code Reference (/vendor/psc) is a static list of product and service codes with what each includes and excludes and the related NAICS codes. The page loads up to 200 codes and filters them in the browser. It shows no counts or awards per PSC.
