Most State agencies are required to use the CALNET 3 Master Contract to purchase mandatory telecommunications services; however, the contract can also be used by other federal agencies and local public entities that are tax-supported and non-profit or that have an eligible joint powers agreement.

Agencies that use it must abide by all of the terms and conditions of the CALNET 3 Master Contract. Here are some examples of customers:

• State Department and Agencies
• State Colleges and State Universities
• Counties
• Cities
• Schools and Community Colleges
• Libraries
• Special Districts (Water, Fire, etc.)
