Secretary of State Shirley N. Weber, Ph.D., Addresses Voter Information Guide Map Typo with Correction Mailing
Sacramento, CA – The California Office of the Secretary of State announced today that a correction notice will be mailed to voter households in response to the discovery of a map labeling error in the official 2025 Voter Information Guide (VIG).
On page 11 of the guide, a proposed congressional district contained in the map provided by the Legislative Analyst’s Office (LAO) was inadvertently labeled as District 22 instead of District 27. A separate map provided by the LAO on page 15 included the correct identification of District 27.
To ensure voters receive accurate information, a correction postcard will be mailed to all voter households who received the guide with the typo. The “https://voterguide.sos.ca.gov/“ website has also been updated to reflect the corrected map.
“Accuracy in voter information is essential to maintaining public trust in California’s elections.” said Secretary Weber. “We are taking swift, transparent action to ensure voters receive correct information. This mislabeling does not affect proposed districts, ballots, or the election process; it is solely a labeling error. Every eligible Californian can have full confidence that their vote will be counted and their representation is secure.”
