Federal buyers assign one NAICS code to each award and each notice. The code describes the kind of business the buyer expects to perform the work, not the item itself; the item is described by the PSC code. The numbers above come from awards and notices carrying this exact code. Related work often sits in the neighboring codes listed below, so watch the neighbors too.

The official definition, with what the code includes and excludes, is on the Census NAICS page linked at the bottom.

How to use this page

Who bought it ranks contracting offices by what they obligated under this code. Who won it ranks vendors after names are resolved to one record each. What it went for shows award size bands; the median describes a typical award better than the average. What recompetes soon lists awards whose period of performance ends inside twelve months.

A code with nothing on record yet says so. History loads one subsector and fiscal year at a time, so quiet codes and older years fill in last. Members see the individual awards and notices behind every number, buyer and incumbent profiles, alerts and briefs.
