Pre-registration is available to eligible 16 and 17-year-olds. Once a voter turns 18, their voter registration will automatically become active. However, you must be a U.S. citizen in order to pre-register or register.

County election offices will begin mailing ballots to active registered voters by March 10. Just fill it out, seal it in the provided envelope and send it off to your county elections office. Make sure it's postmarked by April 8.

If you're dropping off your ballot, it must be delivered no later than 8 p.m. when polls close on Election Day.

All California active registered voters are sent a vote-by-mail ballot roughly a month before an election. That allows local election offices time for thorough verification processes, such as signature matching and accuracy testing. This extended timeframe also accommodates people who don't have time to make it to a vote center on Election Day, providing ample opportunity to cast their ballots. Californians have had the option to vote by mail since 1979, and instances of voter fraud, including with mail-in ballots, are exceedingly rare due to stringent safety protocols. Mail-in ballots are only provided to registered Californians, and there are robust measures in place to prevent forgery, theft and fraudulent activity. In 2012 65.15% of ballots cast were mail-in ballots — 10 years later that number was 91.24%

Voters may vote and return either ballot. Destroy the unused ballot. If the voter uses the suspended ballot the system will automatically set aside that ballot envelope. That ballot will be counted if and only if that is the only ballot returned by the voter.

"Voters are encouraged to call our office to let us know. Replacement mail ballots are typically sent when a voter moves within the county to a new residence address after the initial mailing was sent," said a San Diego Registrar of Voters representative via email.

Ballots in California are available in several languages other than English.

When registering to vote, you can select from the following: Spanish, Chinese, Japanese, Khmer, Korean, Tagalog, Thai or Vietnamese. You can fill out an application online at the Secretary of State's website.

The Voting Rights Act, enacted in 1965, requires the Registrar of Voters to provide language assistance in Spanish, Filipino, Vietnamese and Chinese. To receive voting materials in these languages you can fill out an application.

For people that speak Arabic, Japanese, Korean, Somali, Persian or Laotian, you can request a reference ballot called a "facsimile ballot." It's a copy of the ballot translated into these languages. You can use that copy to mark your choices on an official ballot.

To request a reference ballot you can reach out to the following:

Call (800) 696-0136 (toll free), (858) 565-5800 or email rovmail@sdcounty.ca.gov.

Ask a poll worker at a vote center for a reference ballot. If you need help marking your ballot, you may bring someone with you to the poll to assist you.

Political consultant Tom Shepard said campaigns use databases informed by voter rolls from the Registrar of Voters to target those who haven't voted yet with mailers, texts and phone calls.

That means, voting early can help! Campaigns track voter rolls every 24 to 36 hours, and once your ballot is cast, the mail stops. Plus, early voting means avoiding long lines and ensures your vote counts on time.
