Which companies are the biggest data brokers?

There are various types of data brokers and determining the largest depends on which metrics you’re measuring. For example, you can base your evaluation on which data brokers have the largest consumer databases or which have the most pages indexed in Google and earn the most traffic.

Major data brokers

Major data brokers primarily operate B2B models – they’re companies that sell data exclusively to other businesses, so the average person can’t use them to research someone else. However, major data brokers provide data to numerous marketing databases and people-search sites, which, in turn, anyone can use to find your personal info.

Here are the largest data brokers in this category.

Top 5 data broker companiesConsumer databaseAnnual revenue
Experian300+ million people$9.7 billion
Equifax220+ million people$5.1 billion
Epsilon250+ million people$2.9 billion

The company’s ConsumerView U.S. database includes thousands of data points on more than 300 million American citizens and 126 million households to lend insights into demographics, consumer behavior, personal interests, consumer credit information, and lifestyles. Its credit list features information on 245 million consumers and more than 25 million businesses.


Equifax is one of the biggest data brokers in the U.S., earning $5.1 billion in annual revenue and employing more than 14,000 people worldwide.

With a focus on targeted marketing, Epsilon states it has names and “vital consumer data” on nearly every consumer in the United States.

One of the largest data brokers in America, CoreLogic boasts annual revenue of $1 billion and employs more than 4,800 people worldwide.

Largest data brokers based on traffic and number of pages indexed by Google

Unlike major data brokers that serve the B2B market, numerous other large brokers package data into personal background reports and make them openly available online which poses significant security risks to individuals.

Often referred to as people-search sites, these companies thrive on web traffic, so they give more and more information away for free in an attempt to outrank one another on Google. The highest-ranking sites get the most traffic and earn the most revenue by selling more detailed background reports – exposing your data to the largest number of people and leaving you vulnerable to identity theft, stalking, financial fraud, and other crimes.

Here are the largest data brokers by number of pages indexed per Google and monthly traffic per Similarweb.

List of data broker companiesNumber of indexed pagesMonthly visits
Yellowpages18.2 million15.2 million
ZoomInfo8.29 million7.2 million
Spokeo4.2 million13.5 million
Radaris4.72 million9.4 million

Yellowpages has 18.2 million pages indexed in Google and earns 15.2 million visits a month, making it one of the largest data brokers in the U.S. The site is a business directory that allows you to search for companies by name, type, and location.

How data brokers affect you

Data brokers represent significant privacy risks – so much so that four U.S. states have enacted data broker laws (however, there are no overarching federal data broker laws like GDPR in the European Union).

Data broker activities can influence what advertisements, company offers, and content you see online. They track your demographics, interests, and behavior and provide this information to marketers to serve ads you’re likely to engage with.

While some might consider data collection for targeted advertising helpful, data broker sites also have a significant impact on your digital identity. Profiles on people-search sites contribute vastly to your digital footprint, making it easy for anyone to find sensitive information such as your court records, income, social media accounts, credit score range, and even your photos and videos. What’s more, these sites never verify their data resulting in false information like legal actions or bankruptcies attributed to you instead of a person with the same name.

Worse, scammers can misuse this data with criminal intent:

  • They can steal your identity, make purchases in your name, or hack your online accounts
  • They can impersonate a well-known company and use your personal data to convince you they’re legitimate
  • An ex-partner or a hate group could even look up your address or location history to stalk and harass you

As for major brokers, even though they aren’t selling data to the general public, they are susceptible to data breaches that can put your sensitive information in the wrong hands, including your Social Security number and online account login credentials (if your information was involved in a data breach or you believe you’re a victim of identity theft, contact the Federal Trade Commission here).

How data brokers collect consumer data

Data broker companies tap various sources to collect data, including:

  • Public records
  • Online behaviors (tracked with browser cookies)
  • Online surveys and forms
  • Loyalty and rewards programs
  • Websites and apps (check privacy policy pages to see what information they collect and share)
  • Purchasing data from other companies, such as credit card companies

The information data brokers collect cover numerous areas of an individual’s life, from basic demographics to detailed online activities, including:

  • Personal information: Name, address, email, phone number, family members, property and vehicle records, and court records
  • Demographics: Age, occupation, gender, ethnicity, income and net worth, credit scores, education level, and political and religious affiliations
  • Consumer information: Shopping history and consumer transactions, websites visited, search history, location information, advertisements clicked, newsletter subscriptions, and social posts

The good news is you can opt out of data brokers to protect your data privacy and prevent identity theft, financial fraud, and other crimes.

Choose to opt out of big data brokers automatically

The law requires data broker sites to remove your information on request. Each data brokerage website has its own opt-out procedure, but the process typically involves:

  • Finding the opt-out page or form
  • Finding your profile
  • Filling out an opt-out request
  • Verifying your identity via email or phone
  • Revisiting the site later to confirm your profile was deleted

However, data brokers don’t make it easy to opt out. Most people don’t have the hundreds of hours it takes to remove yourself from all the websites out there – and even if you do, they’ll probably republish your data anyway, making removal a never-ending task.

Onerep helps by scanning 207 data broker sites for your information and automatically submitting opt-out requests for you. We use dummy emails and phone numbers to safeguard your contact info throughout the entire process. Then, we revisit each page to confirm removal, and we regularly rescan each site to ensure they don’t republish your information. If they do, we automatically begin the opt-out process again.

How many data brokers are there in the US?

There are thousands of data brokers in the U.S. At the time of this writing, states with public data broker registries reported 550 (California), 404 (Vermont), and 36 (Oregon) active data brokers, though some companies are exempt from registering.

Who buys data from data brokers?

Many people and organizations buy data from data brokers. Banks and creditors buy data for credit scoring, risk mitigation, and fraud prevention. Retailers buy data for targeted marketing campaigns. Individuals look for data to find relatives and friends, research someone they don’t well, or see who’s behind unknown phone numbers. Criminals buy data to commit scams, steal identities, or locate and stalk their victims.

Is Google a data broker?

Google is not a data broker because it doesn’t directly sell your information. However, it does analyze data to construct demographic and behavioral profiles and share data with third-party advertisers who bid on targeted ad space. The information from people-search sites is indexed by Google and becomes easily accessible to the general public via the search giant.

What do data brokers know about me?

Data brokers know a great deal about you, including your demographics, interests, contact information, consumer information, shopping behaviors, location history, relatives, marital status, income and net worth, credit scores, political and religious affiliations, online activity, health status and medical conditions, court and arrest records, and much more.
