NIGP code

An NIGP code is a number from the NIGP Commodity/Services Code, a classification many state and local governments use to label what they buy, so vendors can register for the items they sell.

When you register as a vendor with a county or its bid platform, you often pick NIGP codes for your products and services. The county then sends bid notices to vendors registered under the matching codes.

Choose codes carefully

  • Too few codes, and you miss bids.
  • Too many unrelated codes, and you get irrelevant notices.
  • Codes are hierarchical: a 3-digit class (for example, a category of road materials) with more specific 5-digit items. Pick the specific items where you can, plus the broader class.

FairCounty reads NIGP codes from bids when counties provide them and matches them to what you sell, so you don't have to register code by code in every county.
