Monday — May 18 — is the last day to register online to vote in the June 2 state primary election.
It’s also your last chance to re-register online if you need to update your voter registration details.
But if you miss this deadline, don’t worry.
You have several options for registering or re-registering in person all the way through June 2, your last day to vote.
Here’s what to know about checking your voter registration, from the May 18 deadline to how to make sure election officials have your correct mailing address.
You can also jump straight to:
I want to register to vote for the first time
What should I do if I’ve moved to a new address or changed my name?
What if I haven’t received my ballot yet?
I’m almost certain I’m registered to vote … but how can I check?
You can check your voter registration status at voterstatus.sos.ca.gov, which will show whether you’re registered to vote and the address associated with your registration.
If your voter registration is active and your address and name are up to date, your ballot should have arrived by now.
You can use voterstatus.sos.ca.gov to check when your ballot was mailed.
You can also use the Where’s My Ballot?
tool to check whether your ballot was sent out, and read our guide on what to do if your ballot never showed up.
What are some reasons I might need to update my voter registration?
Updating your voter registration is also known as “re-registering” to vote — because to update elements of your voter record at registertovote.ca.gov, you’ll need to register to vote again as if you were making a new application.
As a general rule, you’ll definitely need to re-register if your name or address has changed.
But if registering to vote when you know you’re already registered feels weird, don’t worry: this won’t be seen as you trying to fraudulently register to vote twice or anything like that.
Because your voter registration is tied to your social security number and your driver’s license/state ID card number, your new voter registration will be matched with your existing voter registration and your details will be updated.
There will also be a section on the form where you can provide any previous addresses and names you’ve been registered to vote under.
If you want to change your party preference, you’ll also need to re-register to do that.
For smaller changes, your county may allow you to submit a Voter Action Form by mail or online.
For example, if San Francisco residents want to make minor changes to their voter registration, they can use a form from the San Francisco Department of Elections to determine whether they can do so online.
Find your Bay Area county elections office’s website and contact details.
You should update your voter registration if:
If you have moved to a new address within California
If your old address is on your voter registration, then your mail-in ballot will automatically be sent to that address — not your new one.
Your voter registration will only reflect your new address if you’ve manually updated it or if you’ve updated your address with the DMV.
Register to vote with your new address at registertovote.ca.gov.
The state says that you can also send a signed letter to your current county elections official to let them know you’ve moved, along with your date of birth and current address.
Find your Bay Area county elections office’s website and contact details.
If you have legally changed your name
You’ll need to re-register to vote with your new name.
One important thing: Before you do that, the Secretary of State recommends that you update your California driver’s license or identification card with the DMV first.
This is because when you register to vote online, your county elections office electronically requests a copy of the signature the DMV currently has for you.
And if you haven’t updated your signature with the DMV, the signature the agency sends to your county elections office will be the signature for your previous name, not your new one, and your registration will be rejected.
Read how to update your signature with the DMV.
What if you aren’t able to update your details with the DMV first?
The state recommends you select “decline” on the application when asked to use your DMV signature to register to vote — but you’ll have to hit “print” and sign the paper application, which you’ll mail.
Register to vote with your new name at registertovote.ca.gov.
If you haven’t voted in a while
“In general,” the Secretary of State’s office says, you’ll stay registered to vote for as long as you remain at the same address you’re registered with — but “there are cases in which voter registration can be canceled if a voter has not voted in several consecutive general elections.”
So if your ballot hasn’t arrived in May, and you suspect it might be because you haven’t voted in many years, contact your county’s elections office ASAP.

When is my last chance to update my voter registration?
If you forget to re-register with your new address or name, and your ballot is sent out in May to the wrong address or without your current name, don’t worry.
As long as you update your voter registration online at registertovote.ca.gov before the May 18 deadline, your county will just cancel the ballot that went to your old address and send you a new one.
And if things get hectic this month and you miss the May 18 deadline, you can still update your voter registration — you’ll just have to do it in person at that stage.
Vote centers will open in most Bay Area counties on May 23.
Go to your county elections office or an open voting location and ask to register in person via Same Day Registration (also called conditional registration).
You can do this up until when polls close at 8 p.m. on Election Day, June 2.
How can I register to vote for the first time?
You can register to vote if you’re:
A United States citizen and a resident of California,
18 years old or older on Election Day
People who are currently serving a state or federal prison term for a felony conviction cannot vote or register to vote.
You can register to vote online at registertovote.ca.gov before the May 18 deadline.
After that, you can register to vote in person at your county elections office or an open voting location, where you can register through Same Day Registration (also called conditional registration).
You can do this up until when polls close at 8 p.m. on Election Day.
If you’re unhoused or have no fixed address, you can still register to vote by describing the place where you spend most of your time, if you don’t have a street address, including cross streets.
You can register to vote this way via online application before May 18, or on the paper voter registration application you can pick up at any Department of Motor Vehicles field office, or many post offices, public libraries, government offices or your county elections office by request (where you can also use Same Day Registration in person).
When will my ballot arrive?
Every registered voter in California will automatically receive a ballot in the mail, and by this point, you should have received yours if you were correctly registered to vote.
May 4 was the deadline for Bay Area counties to start mailing ballots, though many started several days earlier.
This means your ballot will most likely have arrived in early to mid-May.
You can use both voterstatus.sos.ca.gov and the state’s Where’s My Ballot?
A tool to check whether your ballot has been sent out.
And if your ballot is still missing, don’t worry: You have options.
Read our 2025 guide for what to do if your ballot doesn’t show up.
You can use the ballot to cast your vote, or you can forget it and request a fresh one at a voting location.
The one that arrived in the mail will be canceled.
