What is the importance of the NIGP Codes and can I change my NIGP Codes after I register?
The NIGP Code is a type of Standard Industry Code (SIC) used by governmental organizations. It is highly recommended that vendors carefully select the NIGP commodity codes that most accurately reflect the commodities and services their company provides. Bid invitations are sent to those bidders and suppliers who have registered the specified NIGP codes on their profile. You may change your NIGP Codes by logging in and going to the area where you maintain your contact information. If you don’t find an exact match to the goods that your company supplies, choose the closest NIGP Code or select multiple codes.
