How to vote in person in San Diego County You can vote in person two ways: with or without your mail ballot. Without your mail ballot: You can arrive to any local voting center and check-in. You will have to sign an ePollbook (also called the electronic roster of voters). Once checked-in, the barcode on your mail ballot return envelope is automatically suspended. You will then be directed to a touchscreen ballot marking device to make your selections. Then, on the paired printer you will print out your official ballot with your selections. This official paper ballot is what goes inside the official ballot box to be tabulated at the Registrar of Voters office. If you do have your mail ballot: You will follow the same check-in process. You do not need to bring the return envelope. However, the Registrar of Voters says it’s good practice to bring in your mail ballot packet and surrender it to poll workers. You will then be given a secrecy sleeve to place your ballot inside and then asked to slide your ballot toward the top of the sleeve so the sequence number at the top of the ballot can be seen by the poll worker. This will conceal any already marked contests while the poll worker goes through the steps to ensure that your ballot that you carried in is in fact the voter’s correct ballot type. Then, you will either be directed to a voting station to mark your ballot with the pen or marker provided by the poll worker or if you already marked your ballot prior to arriving at the vote center, you will be directed to the check-out station to have the poll worker cast their ballot into the ballot box. Once the ballot is placed inside the ballot box, your vote has been submitted. Can I drop off my mail ballot at a vote center? Yes! If you’ve already filled out mail ballot but don’t want to drop it in the mail, you can drop it off at a vote center in person. Follow these steps: Carry in the official ballot you received in the mail Check in at the vote center Sign the electronic roster Cast your ballot, it does not have to be in its return envelope If it is sealed inside its return envelope, you can still drop it off at the vote center. What if I lost my mail ballot or made a mistake on my mail ballot? If this is the case, you can instead vote in person using a ballot marking device at any vote center.
