National Voter Registration Day
September 28, 2021

Dear Voters,

Please join me in celebrating National Voter Registration Day on September 28, 2021.

National Voter Registration Day is a nonpartisan civic holiday that was established to encourage every citizen to exercise their constitutional right to vote. Volunteers and organizations mobilize on this day to educate American citizens on the importance of registering to vote and voting.

Registering to vote and voting in San Mateo County is easy, convenient, and safe.

You may register at any time online or by mailing a completed Voter Registration Form to the San Mateo County Registration & Elections Division. Forms are also available in person at public libraries, city and county offices, California Department of Motor Vehicles offices, and U.S. Post Offices. Sixteen and seventeen-year-old residents are also eligible to pre-register to vote.

For more information on registering to vote, please visit our website at www.smcacre.org/register-vote or call our office at 650.312.5222.

Registering to vote and actively participating in the electoral process is the foundation of our democracy. The right to vote is your fundamental constitutional right and civic responsibility.

Your vote will ultimately determine the future of your communities, California, and the nation. I fully encourage you to register to vote today and actively participate in the electoral process!
