NOTE: Premier Elections Solutions was formerly known as Diebold Elections Systems.

* Los Angeles County's Ink-a-Vote Plus machines scan ballots at the polls for errors (overvotes or blank ballots) though ballots are counted centrally.

** Alpine and Sierra counties are vote-by-mail counties.

*** Nevada County allows voters to choose whether to cast a paper or electronic ballot.

Contact your county election office for more information about local voting equipment and procedures.

View historical county-by-county directories (since 2002) and statewide maps of voting systems (since 2003).
