Understanding your City of Hayward data breach notification letter
If a City of Hayward letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
The City of Hayward is a municipal government entity responsible for providing essential public services to its residents and managing city operations. As a government body, the City typically collects and stores sensitive personal information including Social Security numbers, driver’s license numbers, tax records, and utility account details necessary for administrative and public safety functions. This data breach was officially reported to the California Attorney General in 2025, and the City has since issued formal notification letters to all individuals whose personal information may have been impacted. If you received such a letter, it indicates that your sensitive records were involved in this security incident, and you should review the provided documentation carefully to understand the specific risks to your personal data.
What to do after the letter

Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
