NIGP Codes

NIGP Class and Class Item Codes identify the scope(s) of work as defined by the National Institute of Governmental Procurements. This five-digit code establishes and defines the detailed scope(s) of work for the contract. The first three digits of the NIGP code represents the Class or broad category of the work to be performed, and the second two digits of the NIGP code identify a more specific focus of work within the Class category.
