Understanding your AT&T data breach notification letter

If a AT&T letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now — one of roughly 73,000,000 people notified.

Why you received this letter

AT&T has reported a significant data leak impacting approximately 73 million current and former account holders. Customer records containing Social Security numbers, account information, and dates of birth were identified on a hacking forum. This incident, initially detected in April 2024, may pose risks of identity theft and fraud for those affected.

  • Social Security numbers
  • account information
  • dates of birth

What to do after the letter

  1. Confirm the notice is genuine

    A legitimate AT&T notice references the specific incident reported to the TX 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
