Buyers/Agencies can filter through vendors based on the NIGP codes that are selected on Vendor profiles and, once a list of Vendors has been selected, they send a notification to the selected Vendors.
Just having the NIGP code doesn't guarantee a notification will be sent. However, it helps the Buyer filter through all registered vendor accounts and increases the possibility of them sending a notification.
If you'd like to receive email notifications for updates on specific bids (such as changes to the bid, bid closing dates and awards), you can do so by pulling up the bid on our site, scrolling down to the bottom of the bid page, and selecting Follow. You can also see the NIGP codes selected for the solicitation by the Buyer on this page under the Item Information section.
Here is a guide on updating/managing your NIGP codes:
NIGP Codes (scroll down to Maintaining Commodity Codes and Services).
Please note that you will need to be in the Seller Admin view in order to update NIGP codes. You can switch to Seller Admin by clicking the person icon, selecting Seller, and switching it over to Seller instead.
