How do I register to vote?
You can fill out a voter registration form available at all post
offices, city halls, most public libraries, Department of Motor
Vehicles (DMV) offices and most governmental agencies. Once you
sign the form, just drop it in the mail. Postage is prepaid.
The Secretary of State’s website enables you to fill
out a voter registration form online. The online form uses your
signature on file with the DMV. If you have no DMV signature, you
can print out the form and mail it in.
When must I re-register to vote?
If you move, change your name, or wish to change your political
party affiliation, you must re-register to vote.
The deadline to register to vote for any election is 15 days
prior to Election Day. After the deadline, you can still register
conditionally at the San Mateo County Registration & Elections
Division, 40 Tower Road, San Mateo. Your vote will be counted
once you’re confirmed as an eligible voter. Other satellite
locations may be designated.

Can I register to vote at my business address or can I use my
P.O. Box number?

jurisdictions where you live (e.g., congressional, state
assembly, state senate, municipal, judicial, county,
school and/or special district offices). However, Safe at Home participants can use a
free P.O. Box instead of a home address.
You may use a business address or a P.O. Box as a mailing address

does the County say I’m not registered?

offices are not actually registered. Although they checked the

vote, many forgot to complete the attached voter
registration form. A voter registration form must be
completed, signed and received by the San Mateo County

must re-register at least 15 days prior to an election.

What is Conditional Voter Registration?
During the period of 14 days up to and including Election Day, an
individual may go to the office of their county Elections
Official or designated satellite location to conditionally
register to vote and vote a provisional ballot. This process is
called Conditional Voter Registration (CVR).
In order to conditionally register, the individual must first
complete an affidavit of registration (also known as a voter
registration card). The voter is then given a CVR provisional
ballot to vote.
Once the county Elections Official processes the affidavit of
registration, determines the individual’s eligibility to

will be counted. This process occurs before or during the
