The DMV licenses private businesses as Private Service Bureaus (known as PSB Partners). PSB Partners are authorized to process certain DMV transactions on behalf of their customers. When they use a PSB Partner, customers who normally would need to visit a DMV office can avoid the visit.
The PSB Partner program is convenient for the customers who use the services of the PSB Partners. It also improves efficiency at DMV offices because it reduces the number of transactions DMV must process or the number of individual customers the DMV must serve.
