What happened
Foster City has reported that it identified suspicious activity within portions of its network earlier in 2026. After discovering the activity, the City investigated, secured its systems, notified law enforcement, and engaged an independent forensic security firm. That investigation determined that an unauthorized third party accessed certain City systems and may have viewed or acquired files between February 28, 2026 and March 25, 2026.
The City completed its review of the affected files on June 10, 2026 and determined that they contained personal information. According to the notice, the information involved may have included each individual's name along with additional personal data elements that varied from person to person. The City began mailing notification letters on July 13, 2026, roughly three and a half months after the intrusion window closed, and arranged a complimentary one-year membership in Experian IdentityWorks Credit 3B for those affected.
Because Foster City holds personal information for residents and employees in its role as a municipal government, exposed records may include data that can be used for identity theft or fraud. The public notice does not itemize every category of data or state how many individuals were affected, and the City has said it is continuing to evaluate additional technical safeguards.

Common questions
I received a data breach letter from Foster City. What should I do? +
Keep your notice letter, since it contains your Experian IdentityWorks activation code and serves as evidence. Enroll in the free 12-month Experian IdentityWorks Credit 3B monitoring before the deadline, review your bank and credit-card statements for unfamiliar activity, consider placing a fraud alert or security freeze with the three credit bureaus, and contact a data breach attorney to understand your options.
Am I eligible to join a class action against Foster City? +
Foster City residents and employees who received a notification letter are the most likely to qualify. Eligibility can also depend on your state of residence, the categories of personal data exposed in your individual letter, and whether you experience any documented fraud or losses.
How much money could I receive from a class action lawsuit? +
Data breach class action recoveries vary significantly. Settlements typically range from a few hundred dollars for basic out-of-pocket losses to several thousand dollars for documented identity theft, with class size, damages, and negotiation all affecting the final amount. No payout is guaranteed, and this investigation has not yet resulted in a settlement.
What personal information was exposed in the breach? +
The public notice states the affected files contained your name along with additional personal information that varied by individual. The City did not itemize every data element in the public notice, so you should check your individual letter for the specific information involved in your case.
Did Foster City offer free credit monitoring? +
Yes. The City arranged a complimentary one-year membership in Experian IdentityWorks Credit 3B, which monitors your Experian, Equifax, and TransUnion files and includes identity restoration support and up to $1 million in identity theft insurance. Enrolling before the deadline in your letter does not waive your right to pursue a claim.
How many people were affected by the Foster City breach? +
Foster City has not publicly disclosed the number of affected individuals in its notice. This page will be updated as more information becomes available.
Is there a deadline to take legal action? +
Yes. Statutes of limitations for data breach claims vary by state and legal theory, typically ranging from one to six years. Waiting can permanently bar your claim. Contact us as soon as possible for a free evaluation.
How do I get a copy of the official breach notice? +
The notice was filed with the California Attorney General's data breach notification database, where a copy is publicly available. Dapeer Law can also help you obtain a copy during a free consultation.
