You trust background check services to protect your identity, not expose it. But in early 2024, a shocking breach at National Public Data turned that trust into a nightmare for millions.
According to reports from Bloomberg Law, the incident allegedly exposed up to 2.9 billion records containing highly sensitive personal information linked to approximately 170 million individuals across the United States, the United Kingdom, and Canada.
This article outlines the scope of the breach, the types of data compromised, who may be affected, and the steps individuals can take to protect their information in its aftermath.
What Happened in the National Public Data Breach

The breach happened because a cloud storage system used by National Public Data was not properly secured. The database was left online without a password or any protection, which meant anyone could access it.
Experts believe a third-party vendor may have been responsible for managing this system, but the exact cause is still being investigated.
While some of the information came from public records, putting it all together in one place made it much more dangerous and easier for criminals to use.
The exposed records included very personal details, such as:
- Full names
- Social Security numbers
- Email addresses
- Home addresses
- Dates of birth
- Government ID numbers
- Voter registration information
Incidents like this highlight the importance of understanding data breaches and following effective tips to prevent data leaks.
Could Your Information Be Part of the National Public Data Breach?
Since the data was pulled from a wide range of public sources, the breach covered many states and local agencies. This makes it one of the largest public data exposures ever reported.
Some groups are more likely to have been affected than others, including:
- Government employees, whose work details may have been listed
- Registered voters, especially in states where voting records are public
- Taxpayers, with financial or identity details tied to public filings
- People receiving public assistance, such as housing or healthcare support
- Children and older adults, who might be listed in social service or medical databases
These groups often include people who are more vulnerable to identity theft or scams, which makes this breach even more concerning.
Real-World Consequences of the National Public Data Breach
This data breach isn’t just a headline. It can lead to real problems for people whose information was exposed. Here’s what could happen if your details were part of the leak:
Stolen Identities
With access to your Social Security number and other details, criminals can pretend to be you. They might take out loans, open credit cards, or file fake tax returns using your name.
Credit Card and Bank Fraud
Your financial information could be used to make purchases, withdraw money, or open accounts in your name. It’s important to know how to detect and prevent unauthorized transactions before the damage is done.
Personal Information Made Public
Leaked home addresses or voter registration data could lead to harassment or threats. This is known as doxxing, when someone shares private information online to embarrass or target a person.
Rise in Scam Messages
Scammers may send fake emails or texts using your name and other details to trick you into clicking harmful links. These scams are especially common in places where catfishing happens most often, such as dating apps, social media, and job boards.
Sold on the Dark Web
Your stolen data might end up for sale on the dark web, where criminals buy and trade personal information. Once it’s out there, it can be used over and over again for fraud.
With data breaches like this one growing in size and frequency, taking action right away is critical. This breakdown of data breach tips and tools offers clear steps to strengthen your digital safety.
Steps You Should Take Now After the National Public Data Leak

Because so much personal information may have been leaked, it’s smart to take steps now, even if you’re not sure what was exposed. It’s safest to assume that your Social Security number, phone number, and email address might all be part of the breach.
If Your Phone Number Was Leaked
If your phone number was exposed, scammers might try to trick you through fake calls or texts. They may pretend to be from banks or government offices. Here’s how to stay careful:
- Watch out for scam calls and texts. Don’t give out personal information to unknown numbers.
- Ignore texts from people or companies you don’t know.
- Don’t click links in texts that seem odd or come from unfamiliar numbers.
- Use a reverse phone lookup to check unknown numbers before responding so you can spot scammers before they reach you.
If Your Social Security Number Might Be Involved
A leaked Social Security number can open the door to serious identity theft. Knowing what to do if your Social Security card is stolen gives you a clear path to lock things down and stay protected.
- Freeze your credit with the three big credit bureaus (Experian, TransUnion, and Equifax). This stops anyone from opening new accounts in your name.
- Learn how at the Social Security Administration website.
- Check your credit reports regularly. You can get free weekly credit reports at AnnualCreditReport.com.
- Place a fraud alert with a credit bureau. This tells lenders to double-check before giving credit in your name.
- Keep an eye on your bank and credit accounts for any strange activity or charges.
- If you know your Social Security number was leaked, contact the Social Security Administration for help: ssa.gov
If Your Email Address Was Leaked
If your email was part of the leak, hackers could try to break into your accounts or send fake emails. Making your email more secure helps keep your other accounts safe, too.
- Change your email password right away. Make sure it’s strong and not used for any other account.
- Turn on two-factor authentication (2FA) to make your email more secure.
- Update your passwords for other accounts that use this email, especially if you use the same password elsewhere.
- Be careful with emails from unknown senders. Don’t click on links or open attachments unless you’re sure they’re safe.
