The City of Tulsa Purchasing website is devoted to suppliers interested in providing supplies, equipment, vehicles, information technology systems, and most services, for all City departments. Purchasing uses NIGP (National Institute of Governmental Purchasing) commodity codes, at a 5 digit level, to keep track of the items we buy. In order to receive notice of opportunities to bid or quote on specific commodity codes, you must register as a supplier and you must select the commodity codes you are interested in. Our system automatically sends notice to all suppliers registered for a particular code, when we buy that item.
The City uses the National Institute of Government Purchasing (NIGP) Commodity System. Tangible products are numbered 050-00 through 899-00 (digits 4 & 5 will always be zero). All services are numbered 900-00 through 999-99 (digits 4 & 5 will never be zero).
