What Are Data Brokers and Why Should You Care?

If you've ever searched your own name online and found a website listing your home address, phone number, estimated income, and names of your relatives — you've met a data broker. These are companies whose entire business model is collecting, packaging, and selling your personal information to anyone willing to pay.

The global data broker market was valued at US$278 billion in 2024 and is projected to reach US$512 billion by 2033. There are approximately 5,000 data broker companies operating worldwide, and an estimated 70% of the world's online population has personal information collected by them — often without explicit consent. Most people have never heard of any of these companies. That's by design.

What data brokers actually know about you

Data brokers aggregate information from dozens of public and commercial sources. A typical profile on a "people search" site might include:

• Full name and any known aliases or maiden names
• Current and past home addresses — sometimes going back decades
• Phone numbers — mobile, landline, and sometimes work numbers
• Email addresses — personal and professional
• Names of relatives and associates
• Estimated income and net worth
• Property records — what you own, when you bought it, and what you paid
• Court records — including traffic offences, lawsuits, and bankruptcies
• Social media profiles
• Education and employment history

Some brokers go further. Marketing-focused data brokers maintain profiles that include your shopping habits, health interests, political leanings, religious affiliation, and whether you're likely to be planning a holiday, buying a house, or expecting a child.

Where they get it

Data brokers aren't hacking into databases. Most of their data comes from perfectly legal sources:

• Public records — voter rolls, property deeds, court filings, business registrations. These are government records available to anyone.
• Commercial transactions — loyalty card programmes, warranty registrations, magazine subscriptions. When you fill in a form with your details, that data often gets sold.
• Social media — anything you post publicly is fair game. Profile information, check-ins, likes, and friend lists all feed into broker databases.
• Other data brokers — brokers buy and sell data to each other, creating an interconnected web that makes complete removal difficult.
• App data — many free apps sell location data and usage patterns to brokers. Those "free" weather and flashlight apps exist for a reason.

Why this matters for executives and their families

If you're in a leadership position, data brokers are a specific risk multiplier:

• Physical security. Your home address, daily routine locations, and family members' details are available to anyone with a credit card and a search engine. This is a real concern for executives who deal with disgruntled employees, competitors, or activists.
• Social engineering. Detailed personal information makes phishing attacks far more convincing. An email that mentions your spouse's name, your home suburb, and a recent property transaction doesn't look like spam — it looks like it came from your bank.
• Reputation risk. Court records, property transactions, and business relationships taken out of context can be weaponised. Journalists, competitors, and litigants routinely use data broker sites for research.
• Family exposure. Your profile typically includes your children's names and ages, your spouse's details, and your parents' information. Their data is exposed because of you.

The biggest data brokers you should know about

These are some of the most widely used data broker and people-search sites. If your information is online, it's likely on several of these:

• Spokeo — aggregates social media, public records, and marketing data. Free basic search; detailed reports cost around US$15.
• WhitePages / WhitePages Premium — one of the oldest people-search sites. Includes phone numbers, addresses, and background check data.
• BeenVerified — combines public records with social media data. Subscription-based, widely used for background checks.
• Intelius — focuses on background checks and people searches. Owned by the same company as WhitePages.
• TruePeopleSearch — completely free, which makes it one of the most accessed. Displays addresses, phone numbers, and relatives.
• Acxiom (now LiveRamp) — enterprise-scale data broker used by major corporations for targeted advertising. Claims to hold files on 2.5 billion people with up to 3,000 data points per person.
• PeopleFinder — provides detailed personal reports including property ownership and potential criminal records.

How to remove your data

Here's the uncomfortable truth: there is no single "delete me from the internet" button. Each broker has its own opt-out process, and many of them are deliberately tedious. But removal is possible, and it works.

The manual approach

Every major data broker is required to offer some form of opt-out. The process typically involves:

1. Finding your profile on the broker's website
2. Locating their opt-out or removal request page (often buried in the footer)
3. Submitting a request with enough information to identify your record (usually your name and address)
4. Waiting 2–6 weeks for processing
5. Checking back to confirm removal

The catch: brokers often re-acquire your data within months. Removal isn't permanent unless you repeat the process regularly or prevent new data from being collected.

Your legal rights

Depending on where you live, you may have legal tools available:

• GDPR (Europe, UK) — you have a right to erasure. Brokers must delete your data upon request and cannot charge you for it.
• CCPA/CPRA (California) — California residents can request deletion and opt out of the sale of personal information.
• Australian Privacy Act — organisations must take reasonable steps to destroy personal information they no longer need. You can request correction or deletion. The OAIC has named data brokerage as a regulatory priority for 2025–26, signalling increased enforcement.

A formal legal request (citing GDPR or equivalent) tends to get faster results than a standard opt-out form. Many brokers have dedicated compliance teams for these requests.

Keeping your data off broker sites long-term

Removal is only half the battle. To reduce how quickly your data reappears:

• Use a PO Box or virtual mailbox for any public filings (business registrations, domain registrations, property if possible).
• Minimise form-filling. Every warranty card, competition entry, and loyalty programme feeds the broker ecosystem. If a form asks for more than it needs, leave optional fields blank or use a secondary email.
• Review app permissions. Revoke location access for apps that don't need it. Audit your phone's permission settings monthly.
• Use privacy-focused alternatives. A VPN, a privacy-focused search engine, and a disposable email service for online shopping all reduce the data trail you leave behind.

Data brokers exist because personal data is valuable. You can't stop the industry, but you can make yourself a much harder target. Start with the biggest exposures, automate what you can, and check back regularly.
