Understanding your CHP 11-99 Foundation data breach notification letter

If a CHP 11-99 Foundation 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 CHP 11-99 Foundation has reported a data security incident that occurred on September 16, 2025, potentially involving personal information. This event was officially filed with California authorities on April 1, 2026, indicating that individuals who received notifications had their data within the affected systems.

What to do after the letter

  1. Confirm the notice is genuine

    A legitimate CHP 11-99 Foundation notice references the specific incident reported to the California Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.

  2. 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.

  3. Protect your accounts and credit

    Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.

  4. Check the record against the public filing
