The Registrar of Voters updates registration records daily based on information provided by voters and official government sources. In 2024, there were 974,220 voter registration updates made to Orange County voter registration records, an average of 81,185 transactions per month.
Following the 2024 Presidential General Election, OCROV cancelled more than 176,000 inactive voters who were sent a National Voter Registration Act Section 8(d) notice prior to the 2022 General Election.
Below are links to annual reports generated by our election management system that provides an accounting of all updates to voter registration records since January 1, 2020.
Annual Voter File Maintenance Reports:
In addition to complying with a State legal mandate to update a registration record within five business days of notification from the voter or an official government source, OCROV also accesses third-party data to identify possible voter address and status changes that can be further researched to maintain accurate voter registration records. This includes comparing our voter information with consumer credit reporting agency data before all statewide elections.
A California voter’s registration record cannot be modified based on third-party data. However, OCROV does use the third-party information to contact the voter to confirm the accuracy of the information.
If evidence of an illegal registration is submitted to us, OCROV reports this to the Orange County District Attorney and/or California Secretary of State for investigation. OCROV is not authorized by California law to investigate, regulate, or prosecute alleged voter fraud.
As a result of OCROV’s daily voter file maintenance work, the percentage of ballots returned as undeliverable in 2024 was substantially lower than the national undeliverable first-class mail rate as reported by the United States Postal Service:
- 2024 Presidential Primary Election Ballots – 1.6 percent undeliverable
- 2024 Presidential General Election Ballots – 1.7 percent undeliverable
- FY 2024 All First Class Mail – 4.3 percent undeliverable
