To determine whether your entity qualifies as a HUB, you must complete a HUB application through the Comptroller’s Office.  Those who qualify will be listed in the Comptroller’s online HUB directory.  HUB certification is free and valid for four years when obtained directly from the Comptroller’s Office.  Vendors may also receive state HUB certification through a local government or nonprofit organization, though these certifications may need to be renewed more often.  Visit:
