Heritage Bank, a financial institution serving Washington, publicly reported a data security incident on April 23, 2026. If you have received a data breach notification letter from Heritage Bank, this document is a formal acknowledgment that some of your private information may have been accessed by unauthorized parties.

The specific data categories reported exposed in this incident include your Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Home Address, Telephone Number, and Credit Score Information. The compromise of these highly sensitive details significantly increases the risk of financial fraud and identity theft, as they provide malicious actors with the tools to impersonate you.

With information like your Social Security Number, financial account numbers, and home address, criminals could attempt to open new lines of credit in your name, access existing accounts, or conduct unauthorized transactions. It is important to act promptly to safeguard your financial and personal well-being by monitoring your accounts and understanding your rights.

Financial institutions like Heritage Bank are required by law to implement robust security measures to protect customer data. A data breach of this nature suggests that those safeguards may have been insufficient, leaving customer information vulnerable. Receiving a notification letter establishes that you are among those whose data was compromised.

If you have received a data breach notification letter from Heritage Bank, carefully review its contents for any specific instructions or details it may provide. Consider what steps you can take to protect yourself. To understand your legal options and how this incident might affect you, we offer a complimentary case review for Washington residents.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • 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.

  • 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.

  • 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.

The filing does not give a count of affected people and lists the following information as involved: Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Home Address, Telephone Number, Credit Score Information. Your own letter is the best guide to what was exposed about you, since notices are usually tailored to each person.
Did Heritage Bank offer free credit monitoring?
Check your letter from Heritage Bank. If free credit or identity monitoring is offered, the enrollment code and deadline are printed in the notice itself. Because Social Security numbers are listed in this filing, identity monitoring and a credit freeze matter more than usual. Signing up doesn't waive any legal rights you may have.
What should I do after getting the Heritage Bank data breach notice?
Keep the letter and the envelope, and note the date it arrived. Freeze your credit with Equifax, Experian and TransUnion, change any passwords the notice mentions, and sign up for any free credit monitoring the letter offers. Then check whether you may have a claim.

You usually don't have to join a class action to be included — if a settlement is reached, class members are notified and can file a claim.
Do I need a Heritage Bank data breach lawyer or attorney?
Talking to a data breach attorney costs nothing here. A lawyer can read your notice, explain your rights under your state's law and tell you whether a claim makes sense.
How much could a Heritage Bank data breach settlement or claim be worth?
There is no set amount, and no Heritage Bank settlement is confirmed here. In past data breach settlements, payments depended on what data was exposed and on documented losses — fraud, out-of-pocket costs and time spent dealing with the breach. The filing lists Full Name, Social Security Number, Date of Birth as involved. Keep receipts and records; they're what damages claims are built on.
Can I sue Heritage Bank over the data breach?
It depends on what was exposed, the law in Washington and your own state, and whether you've been harmed. Most people take part through a class action rather than suing alone. Keep your notification letter — it's the proof that connects you to the breach.
