What Is a Data Broker?
There are companies that know where you live, who your relatives are, what you earn, and what you drive. They sell that information to anyone willing to pay. They're called data brokers, and most people have never heard of them.
The Simple Definition
A data broker (also called an information broker or people-search site) is a company that collects personal information about individuals from public and private sources, compiles it into detailed profiles, and sells access to those profiles—usually without the subject's knowledge or consent.
Unlike Facebook or Google, which collect your data to show you ads, data brokers sell your information directly to third parties: marketers, background check companies, employers, landlords, private investigators, law enforcement, and in some cases, scammers and stalkers.
By the Numbers
- • $280 billion — the size of the global data broker industry
- • 4,000+ data broker companies operating in the US
- • 240 million Americans have detailed profiles on broker sites
- • $0.50–$15 — what it costs to look up a person
Where Do Data Brokers Get Your Information?
Data brokers are legal because they rely on publicly available information. Here's where they get it:
🏛️ Public Records
Voter registration rolls, property deeds, court records, marriage and divorce filings, bankruptcy records, DMV data, and professional licensing databases are all public information that governments make freely accessible. Data brokers harvest all of it automatically.
📦 Loyalty Programs & Retail Data
When you sign up for a loyalty card, your purchase history and demographics get sold to data brokers. That grocery store rewards card has been sharing what you buy with dozens of companies you've never heard of.
🌐 Social Media & Online Activity
Public social media profiles, forum posts, comment sections, and website registrations all contribute to your profile. Even things you consider private may be scraped if privacy settings allow any public access.
📋 Other Data Brokers
Data brokers buy from each other constantly, cross-referencing and filling in gaps. Your data flows between hundreds of companies, each adding a few more details.
📫 Direct Data Collection
Surveys, sweepstakes entries, magazine subscriptions, and warranty registrations often sell your data directly to brokers. That contest you entered in 2012 is probably still generating data broker revenue.

Who Uses Data Brokers?
Is It Legal?
In most of the US, yes. Data brokering is largely legal because the information they collect is technically "public." Congress has considered federal data broker legislation for years without passing anything comprehensive. The result is a patchwork of state laws:
- California (CCPA/CPRA): Strongest protections — residents can request data deletion and opt out of sale
- Virginia, Colorado, Texas, Connecticut: Similar but narrower consumer data rights
- Most other states: Very limited protections — data brokers operate largely unchecked
Even if you don't live in California, most major data brokers have extended CCPA opt-out rights to all US residents. It's operationally simpler for them than maintaining 13+ separate state workflows.

How to Remove Yourself
Every major data broker has an opt-out process. With 500+ sites, manual opt-outs would take 150–200 hours total. And you'd have to repeat it every few months as brokers re-harvest your data from new public records.
Manual approach: Search for your name on each site, find the opt-out form (usually buried in the footer under "Privacy" or "Do Not Sell"), and submit a request. Each site has a different process.
Automated approach: Services like GhostVault automate opt-out requests to 500+ sites and re-submit them automatically when your data reappears, handling the ongoing maintenance that makes manual removal unsustainable.
