Commonly recommended next steps

Freeze your credit
Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.
Guard against tax fraud
File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.
Watch your financial accounts
Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.
Check for medical identity theft
Review the Explanation of Benefits statements from your health insurer for services or claims you never received, which can signal misuse of your medical identity.
Stay alert to targeted scams
Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.
Keep your notification letter
Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
