Going Green 


The County of Sonoma is committed to becoming a more sustainable and energy efficient organization. The Registrar of Voters Office is proud to be a part of this effort and urges voters to help too.

Registering online, voting by mail, and accessing your sample ballot and voter information online can all help reduce a significant amount of paper and other resources.

Online Registration

It’s fast, it’s easy, it’s free, and now It’s Paperless!

In September 2012 the California Secretary of State’s Office launched the California Online Voter Registration (COVR) portal. Anyone eligible to register and vote, or preregister to vote (16 or 17 year olds), can now go online to registertovote.ca.gov and complete an application to register to vote. With the click of a mouse, anyone can register to vote anywhere in the state.

The Registrar of Voters Office is committed to expanding our voter registration outreach efforts to target under-represented groups (especially our youth) and encourage them to complete a registration form online.

Our vote IS our voice. We want every voice to be heard.


Step 2: Vote-by-Mail

Voting by mail saves time, money and reduces gas emissions!

Any registered voter can also apply for Permanent Vote by Mail status

How to Apply

There are several ways you can become a vote by mail voter:

  • On the California Online Voter Registration form check the box that says “Yes, I want to be a Permanent Vote by Mail voter. Or, initial that line on the paper registration form.
  • Print the Vote-By-Mail Ballot Application (PDF: 48 kB). Sign the form and return it to the Registrar of Voters Office in person or by mail.
  • Return the application on the back of the County Voter Information Guide.
  • Send in a written, signed note requesting a ballot by mail, must be received in our office at least 7 days before an election.

Why Vote by Mail

  • It’s less expensive than voting at a polling place. Vote by Mail ballots are mailed at Standard Non-Profit rates.
  • Vote in the comfort of your own home. Then return your ballot in the postage paid envelope provided. With fewer cars being driven to polling places, we can reduce the level of Gas Emissions.
  • Three quarters of the voters in our county are permanent Vote by Mail voters. Increasing that number will save taxpayer dollars.

Options for Receiving Your County Voter Information Guide

Inquire about the availability of documents in alternate formats.

You have a choice in how you receive your County Voter Information Guide. Beginning January 1, 2011, state law (AB1717) allows voters to ‘go green’ by choosing to opt out of receiving their County Voter Information Guide by mail, and accessing it online instead.

How do I change the way I receive my County Voter Information Guide?

Use the online form linked below to request that mail delivery of your County Voter Information Guide be stopped, OR to restart mail delivery again if you previously had it stopped.

County Voter Information Guide – Opt Out/Opt In Form

Please keep in mind that depending upon when you submit your form, your County Voter Information Guide mailing for the upcoming election may already be in process. When selecting your options, (opt out/in) may not take affect until the following scheduled election. County Voter Information Guides are available online 30 days before each election.

The law requires the County election official to confirm a voter’s identity. The online form will require that you provide either your California driver’s license or identification card number, or the last four digits of your social security number. The driver’s license or last portion of the social security number are only required for the online form due to the absence of a signature.  Any information provided by the voter will remain confidential by the elections officials.

If I decide to stop receiving my County Voter Information Guide by mail, where can I find it online?

Prior to an election, your County Voter Information Guide will be available for you to read online on the Sonoma County Voter Registrar of Voter website. A link will be posted in advance of each election.

I receive my County Voter Information Guide by mail now and I don’t want that to change.

No problem. If you are currently receiving your County Voter Information Guide by mail and you want to continue, you don’t need to do anything. There’s nothing you need to fill out. Your County Voter Information Guide will continue to be sent to you by mail.

The Drivers License/California ID or Social Security Number are only required for the online form to confirm your identity due to the absence of the signature.
