Is it true that voter registration lists are used to select citizens for jury duty?

Yes. California State Statutes require that lists of registered voters be provided to the Jury Commissioner to be used for jury duty selection.

Why am I receiving multiple jury summons?

The Jury Commissioner selects jurors from lists provided by the Department of Motor Vehicles and the County Voter Registration Unit. If your name appears differently on your driver's license and voter registration file, you may receive multiple notices. To remedy this situation, complete a new voter registration form with your name printed as it appears on your license and return it to the San Mateo County Registration & Elections Division at 40 Tower Road, San Mateo. You may also re-register online at

If I cancel my voter registration, can I be certain that I will not get a summons for jury duty?

No. It has no effect on future jury duty summons. The Jury Services Division requests a list of all active voters. The law also requires that lists of licensed drivers, obtained from the Department of Motor Vehicles (DMV), be made available to the Jury Commissioner.
