You can register to vote in California using a state ID, passport, or other documents instead of a driver's license

California does not require a driver's license to register to vote. The state accepts multiple forms of identification, and you can complete voter registration online, by mail, or in person at various locations. If you don't have a driver's license, you'll use your California state ID number, passport number, or the last four digits of your Social Security number during registration — whichever document you have on hand.

The California Secretary of State runs voter registration and accepts applications up to 15 days before Election Day. Same-day registration is also available at polling places on Election Day itself, which means you have a backup option if you miss the earlier important date.

Key Takeaways

  • California accepts a state ID, passport, tribal ID, or Social Security number in place of a driver's license for voter registration.
  • You can register online at registertovote.ca.gov, by mail using the California Voter Registration Form, or in person at your county elections office.
  • Registration closes 15 days before Election Day, but you can still register and vote on Election Day at your polling place.
  • If you provide a state ID or passport number during registration, the state will verify your citizenship and residency automatically.

What identification documents California accepts

California's voter registration system accepts several forms of ID. A California state ID is the most direct substitute for a driver's license — it's issued by the DMV and serves the same verification purpose. A U.S. passport or passport card also works. If you have a tribal ID issued by a federally recognized tribe, that counts as well.

If you don't have any of those documents, you can provide the last four digits of your Social Security number. This is the most common fallback. During registration, you'll enter whichever number or ID you have, and California's system will cross-check it against state and federal records to confirm your citizenship and California residency.

You do not need to bring the physical document with you to register online. You only need the number or ID number itself. If you're registering in person or by mail, having the document on hand makes the process smoother, but staff can often help you locate the information if you're unsure.

Registering online at registertovote.ca.gov

The fastest route is online registration through the official California Secretary of State website. Go to registertovote.ca.gov and enter your name, date of birth, California address, and citizenship status. When prompted for identification, select the type you have — state ID, passport, or Social Security number — and enter the corresponding number.

The form takes about five minutes to complete. You'll receive a confirmation email when ready, though your registration won't be official until the county elections office processes it, which typically happens within a few days. If you're registering before the 15-day important date, you'll be on the rolls by Election Day. If you register after that important date but before Election Day, you can still vote using a provisional ballot.

Online registration is available 24/7 and requires no documents to be mailed or scanned. This is the method most people without a driver's license use because it's the simplest.

Registering by mail using the paper form

You can also register by mail using the California Voter Registration Form, which you can read from the Secretary of State website or request by phone at 1-800-345-8683. Fill out the form with your name, address, date of birth, and citizenship information. In the identification section, write your state ID number, passport number, or the last four digits of your Social Security number.

Mail the completed form to your county elections office. The address for your county is listed on the Secretary of State website. Mail registration must arrive at your county office by the 15-day important date before Election Day — not postmarked by that date, but actually received. This means you should mail it at least a week earlier to account for postal delays.

If you're close to the important date and worried about mail delivery time, in-person registration at your county elections office is faster and guarantees your form is received the same day.

Registering in person at your county elections office

Every California county has an elections office that accepts voter registration applications in person. You can find your county elections office address and hours on the Secretary of State's website or by searching "[your county] elections office." Bring a form of ID if you have one — your state ID, passport, or any document showing your name and current address — though it's not required if you can provide your Social Security number.

Staff will help you complete the registration form on the spot. If you have questions about what information to enter or which ID number to use, they can guide you through it. Registration is processed when ready, and you'll receive a confirmation card in the mail within a few days.

County elections offices are open during standard business hours, and many stay open late on certain days before Election Day. Call ahead to confirm hours, especially if you're planning to visit close to the important date.

Registering on Election Day at your polling place

If you miss the 15-day registration important date, you can still register and vote on Election Day itself. When you arrive at your assigned polling place, tell poll workers you want to register. They'll provide you with a registration form and a provisional ballot. You'll complete the registration form with your name, address, date of birth, citizenship status, and your state ID number, passport number, or Social Security number.

Your provisional ballot will be counted once your registration is verified, which usually happens within a few days after Election Day. You don't have to wait for confirmation — you vote when ready, and the county verifies your registration afterward. This is a full vote, not a lesser form of voting; the only difference is the timing of the verification.

Election Day registration is available at every polling place statewide. Bring any ID you have, though it's not required if you can provide your Social Security number to poll workers.

What happens after you register

Once your registration is processed, you'll receive a voter information card in the mail showing your polling place, registration status, and Election Day details. This card is not required to vote — your name in the system is what matters — but it's useful to have because it confirms your polling location.

If you move within California, you can update your registration online, by mail, or in person using the same methods. If you move out of state, your registration will be cancelled automatically once the state receives notification from the U.S. Postal Service or another agency.

Your registration remains active for all elections — federal, state, and local — until you move out of California or request removal.

Frequently Asked Questions

Do I need to show my state ID or passport in person to register, or just provide the number?

You only need to provide the number. If you're registering online or by mail, you never show the physical document. If you're registering in person at a county elections office or polling place, having the document helps staff verify the number, but you can register with just the number if you have it memorized or written down.

What if I don't have a state ID, passport, or Social Security number?

This is rare, but if you have none of these, contact your county elections office directly. They can work with you to verify your identity and citizenship using other documents, such as a birth certificate, utility bill, or lease. Call the office or visit in person to discuss your specific situation.

Can I register online if I'm not a U.S. citizen yet but have a state ID?

No. Voter registration requires U.S. citizenship. During online registration, you'll be asked to confirm your citizenship status. If you're not yet a citizen, you cannot register. Once you become a citizen, you can register using the same online system.

If I register after the 15-day important date but before Election Day, will my vote count?

Yes, your vote will count. You'll cast a provisional ballot, and your registration will be verified within a few days. Once verified, your provisional ballot is counted as a regular vote. You don't need to do anything else — the county handles the verification automatically.

Can I register at the DMV without a driver's license?

Yes. California DMV offices offer voter registration as part of their services. When you visit for any reason — to get a state ID, renew an ID, or just to register — you can ask for a voter registration form. Staff will help you complete it, and you can use your state ID number or Social Security number just as you would online or by mail.
