Blanket Authorization Purchases

PDF link


A blanket authorization provides a limited direct authority to purchase goods and/or services from one or more vendors. A blanket authorization is established for a specific period of time.

NOTE: When appropriate and allowable, Purchasing Services encourages departments to use departmental purchasing cards, rather than blanket authorizations, to purchase goods and services from external vendors. Purchasing card use increases the efficiency, accountability, and tracking of transactions. See 70.08.

Types of Blanket Authorizations

The following types of blanket authorizations are in use at the University.

All-University Blanket

Any University department may use an all-University blanket authorization to purchase goods and services from a specified vendor.

The University has established a limited number of blanket authorizations with selected vendors for specific goods and services. University departments may make direct purchases from these vendors. Departments may place orders by telephone, mail, fax, or in person.

Sundry Blanket

In unusual circumstances, Purchasing Services may establish a sundry blanket authorization for a single department to use to purchase goods and services from various vendors.

Department Blanket

Purchasing Services may establish a department blanket for a single department to use to purchase goods and services from a specific vendor. Most often, competitive bidding is required to establish such a blanket.

Internal Blanket

A department may establish an internal blanket authorization with a University service center to purchase goods and/or services. The requesting department submits a completed Interdepartmental Requisition and Invoice (IRI) to the vendor department to establish the blanket authorization. See 70.05 and 70.06.


The following restrictions apply to blanket authorization purchases:
