  • driver license numbers

Fidelity Investments has confirmed an unauthorized access incident that impacted approximately 77,000 individuals. The company reported that two customer accounts were improperly used to access documents containing the personal information of other customers. This incident occurred on August 17, 2024, and was officially reported to the Massachusetts Attorney General on March 25, 2026.

According to Fidelity's filing, the types of data potentially exposed in this breach include names, Social Security numbers, and driver license numbers. If your notification letter from Fidelity Investments indicates that any of these specific data types were compromised, it means that this sensitive information could be at risk.

Receiving a data breach notification letter is often the first step in understanding your exposure. While Fidelity is monitoring the situation, individuals who received a letter should take immediate steps. Reviewing the details in your letter carefully is crucial, as it will specify exactly what data of yours was involved.

One critical action is to remain vigilant for any suspicious activity related to your finances or identity. Consider placing a fraud alert or freezing your credit with the major credit bureaus. Also, be wary of unexpected communications that ask for personal information, as these could be phishing attempts targeting data exposed in the breach.

Understanding the contents of your breach notification letter and its implications for your legal rights can be complex. Consulting with an attorney can help clarify what the notification means for your specific situation, including potential deadlines and legal avenues available to you.

While this situation is still under investigation by Fidelity, and the Massachusetts Attorney General's office is aware, it is important for affected individuals to understand their options. A legal professional can explain how data breach laws apply to your circumstances and discuss any rights you may have to seek recourse.

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.

  • Replace exposed ID documents

    Contact your state DMV or the issuing agency about replacing an exposed driver's license, passport, or government ID number.

  • 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.

Your legal options after the Fidelity Investments data breach

Can I sue Fidelity Investments over the data breach?
It depends on what was exposed, the law in MA 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.
Do I need a Fidelity Investments data breach lawyer or attorney?
A data breach attorney can explain whether the law in your state gives you a claim and what proof you'd need. Reviews here are free, and these cases are normally taken on contingency.
Is there a Fidelity Investments data breach class action lawsuit?
Law firms often open an investigation after a breach notice like this one, and a class action lawsuit may follow. This page doesn't confirm that a lawsuit has been filed against Fidelity Investments. 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.
How many people were affected by the Fidelity Investments data breach, and what was exposed?
Fidelity Investments reported that about 77,000 people were affected and lists the following information as involved: names, Social Security numbers, driver license numbers. Your own letter is the best guide to what was exposed about you, since notices are usually tailored to each person.
How much could a Fidelity Investments data breach settlement or claim be worth?
There is no set amount, and no Fidelity Investments 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 names, Social Security numbers, driver license numbers as involved. Keep receipts and records; they're what damages claims are built on.
Is the Fidelity Investments data breach letter legit or a scam?
A notice from Fidelity Investments in the mail matches the breach Fidelity Investments reported to the MA Attorney General on March 25, 2026, which covers about 77,000 people. Check that the company name and dates in your letter match that filing. A real notice of data security incident won't ask for your password, Social Security number or a payment — if it does, contact Fidelity Investments through a phone number or website you find yourself.
What should I do after getting the Fidelity Investments 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.
Did Fidelity Investments offer free credit monitoring?
Look for an enrollment code in your Fidelity Investments notice. Companies that offer free credit monitoring after a breach usually include it there, with a deadline to activate. Because Social Security numbers are listed in this filing, identity monitoring and a credit freeze matter more than usual. Using the free service won't stop you from joining a lawsuit or settlement later.
