All businesses participating in the OAG's HUB Program must be certified by the Comptroller's Procurement and Support Services Division, the agency which oversees purchasing for the state. There is no fee to become certified as a HUB vendor. Certified HUBs are listed on a HUB database which is accessible to all state agencies.

Vendors who are interested in becoming certified HUBs may contact the OAG HUB Coordinator, a member of the OAG Procurement Division staff, or the CPA to request a HUB application. Vendor information, including applications for downloading can be obtained via the CPA website.
