Understanding Data Brokers

Data brokers are companies that collect, aggregate, and sell information about individuals from public records, commercial transactions, online activity, and third-party data sources — compiling personal profiles that are then licensed to businesses, marketers, investigators, and others.

Quick Answer: Data brokers build personal profiles by pulling information from public records, purchase history, online tracking, and other data sources, then sell access to those profiles. Most adults in the United States have profiles in dozens of data broker databases containing their name, addresses, phone numbers, relatives, property ownership, and more. This data is often inaccurate, outdated, or misattributed. You can request removal from most consumer-facing data broker sites, but the underlying public records that feed those profiles remain publicly accessible regardless.

Most people are unaware that information about them is being continuously collected, aggregated, and sold. Data brokers operate largely behind the scenes — between the government agencies that create public records and the commercial services that present that information in searchable form. Understanding how this system works explains both why people-search tools exist and why their results are often unreliable.

⚠️ Legal Notice: Data broker activity is governed by a patchwork of federal and state laws. The Fair Credit Reporting Act regulates companies that compile consumer reports for employment, housing, or credit decisions. Many data brokers avoid FCRA requirements by classifying their products as marketing data rather than consumer reports. State privacy laws including the CCPA provide additional rights in some jurisdictions. This guide explains how data brokers operate and does not constitute legal advice.

Why Data Brokers Exist

Large datasets about individuals have significant commercial value. Businesses need to verify customer identities, target advertising to relevant audiences, detect fraud, assess financial risk, and conduct background research. Compiling that information independently would be prohibitively expensive for most organizations — so they buy it from companies that have already done the aggregation work.

Data brokers fill the gap between the thousands of independent government systems and commercial databases that contain information about people and the businesses that want that information in a unified, searchable form. They are essentially industrial-scale information aggregators, and their existence is a direct consequence of the decentralized nature of public records in the United States.

For individuals, the result is that personal information created through routine life activities — buying a home, forming a business, appearing in a court filing, registering to vote — flows into commercial databases that can be accessed by anyone willing to pay.

The Legal Framework

Source: Fair Credit Reporting Act — 15 U.S.C. § 1681 — Cornell LII Source: Driver’s Privacy Protection Act — 18 U.S.C. § 2721 — Cornell LII

The FCRA distinction is the most important for researchers and consumers. When a company compiles a report used for employment screening, tenant screening, credit decisions, or insurance underwriting, it becomes a Consumer Reporting Agency subject to strict FCRA requirements — written consent, data accuracy standards, adverse action procedures, and dispute resolution rights.

Most consumer people-search websites explicitly classify themselves as data brokers rather than CRAs. Their terms of service prohibit using their reports for employment or housing decisions. This classification allows them to operate with significantly fewer regulatory obligations — at the cost of being legally unusable for formal screening purposes.

How Data Brokers Build Identity Profiles

Data brokers use automated matching systems — called entity resolution or identity matching — to combine records from multiple sources into a single profile for each individual. These systems link records using identifiers like full name, date of birth, address history, phone numbers, email addresses, and household relationships.

The process is largely automated. Algorithms assign probabilities that two records belong to the same individual. When enough identifiers match, the system links those records into a single profile.

Because this process relies on probability rather than certainty, errors occur regularly. When multiple individuals share the same name or similar identifying details, records may be incorrectly linked. When addresses or names change, old records may remain in the profile alongside current ones. When data from one source conflicts with data from another, both versions may appear in the same profile.

This is why data broker profiles commonly contain incorrect relatives, outdated addresses, records belonging to a different person with the same name, and conflicting data entries. Professional investigators treat data broker results as starting points — not verified records.

Where Data Brokers Get Their Information

Public Records

Government records are one of the primary sources for data broker profiles. Property ownership records, court filings, business registrations, professional licenses, and voter registration data (in states that allow it) are all collected by data brokers and fed into their databases.

This is the direct connection between public records and data broker profiles: the information you generate through official government activities — buying property, forming a business, appearing in a court case, registering to vote — flows automatically into commercial databases. The government record remains in the official government system, but the data broker now has a copy.

Commercial Transactions

Retailers, financial institutions, loyalty programs, and subscription services generate consumer data through everyday transactions. Purchase history, warranty registrations, subscription lists, and loyalty program membership data are sold or licensed to data brokers and incorporated into marketing profiles.

Online Tracking

Websites and mobile apps collect behavioral data through cookies, advertising trackers, mobile advertising identifiers, and location data. This behavioral information helps build marketing profiles describing consumer interests, purchasing patterns, and online activity.

Third-Party Data Exchanges

Data brokers frequently purchase data from other data brokers. These exchanges allow companies to significantly expand their datasets by combining information from multiple aggregation sources — which also means that errors in one database can propagate through multiple downstream databases.

Major Types of Data Brokers

Marketing and advertising data brokers — compile consumer behavior profiles for targeted advertising. Companies like Acxiom and Experian Marketing Services sell access to profiles describing consumer interests, purchase history, and demographic characteristics. This data is used by advertisers to identify consumers likely to respond to specific campaigns.

People-search data brokers — compile personal identity information accessible through consumer search tools. BeenVerified, Spokeo, Intelius, Whitepages, and similar services are built on top of these aggregated datasets. These are the services most consumers interact with directly.

Risk and fraud data brokers — provide identity verification and fraud detection datasets to financial institutions. Companies like LexisNexis Risk Solutions and TransUnion use aggregated identity data to help banks and financial services companies confirm identities and detect suspicious activity.

Investigative data brokers — provide research platforms used by licensed investigators, journalists, attorneys, and law enforcement. LexisNexis Accurint, TLO, TLOxp, CLEAR, and IRB Search aggregate large volumes of public records and commercial datasets for professional investigative research. Access is typically restricted to credentialed professionals.

How Investigators Use Data Broker Information

For professional investigators, data broker platforms — particularly the professional investigative databases — are valuable research tools in the early stages of an investigation. They help identify potential addresses to research further, locate associated phone numbers or email addresses, identify relatives or business associates, and determine which jurisdictions may contain relevant government records.

The key distinction is how investigators treat this information. Professional investigative databases are used to generate leads and identify search directions — not as the final authoritative source on any finding. Every significant finding from a data broker database is verified through the originating government source before being treated as established fact.

Consumer people-search tools (BeenVerified, Spokeo, Intelius) provide a lower-quality version of this same function for personal research. They are useful for identifying address history and suggesting jurisdictions to search — but their data quality and coverage are significantly lower than professional investigative platforms.

Why Data Broker Data Is Often Inaccurate

Data broker profiles are built through automated aggregation — not human verification. Several structural problems produce systematic inaccuracy:

Name matching errors — automated systems that link records by name regularly merge records belonging to different people who share the same name. John Smith in Chicago and John Smith in Dallas may end up with partially merged profiles.

Address lag — people move frequently, but data broker databases update on varying cycles. A profile may show addresses that are months or years out of date.

Outdated source data — some data broker sources update infrequently. Property records from a county that updates its database annually won’t reflect more recent transactions.

Propagation of errors — when one data broker contains an inaccurate record and sells that data to other brokers, the error multiplies across multiple databases simultaneously.

Lack of verification — unlike a court record or government filing that required a human to submit accurate information under legal obligation, data broker profiles are assembled automatically without any verification step.

For investigators, this means corroboration through official government sources is always required. For individuals concerned about their own data broker profiles, it means inaccurate information may appear in multiple places and require multiple correction requests.

Data Brokers vs. FCRA-Compliant Background Check Services

The most important practical distinction for consumers and employers is between data brokers and FCRA-compliant Consumer Reporting Agencies.

Consumer people-search tools are data brokers. Using them for employment or housing screening decisions violates the FCRA regardless of how accurate their data may be in a specific case.

How to Opt Out of Data Broker Databases

Most consumer-facing data broker services provide opt-out mechanisms. The process varies by service — some use online forms, others require identity verification, and some require mailing a written request.

Major data broker opt-out pages:

Important limitations of opt-outs:

• Opting out of one service does not remove your information from others
• Some services re-populate profiles after opt-out as new data becomes available
• Opt-outs typically apply to the consumer-facing service, not necessarily the underlying data broker that supplies the information
• New data broker services launch regularly — opt-out is an ongoing process, not a one-time fix

Automated Opt-Out Services

For comprehensive removal across dozens of data broker services, automated opt-out tools submit removal requests on your behalf on a recurring basis.

These services are useful for individuals who want comprehensive coverage without managing individual opt-out requests manually. They do not remove underlying public records — only the commercial data broker profiles built from those records.

What Can and Cannot Be Removed

What can be removed:

• Consumer-facing data broker profiles (through opt-out requests)
• Commercial people-search profiles (BeenVerified, Spokeo, Intelius, etc.)
• Some marketing database profiles

What cannot be removed:

• Underlying public records (court filings, property records, business registrations) — these are official government records
• Professional investigative database records (LexisNexis, TLO, CLEAR) — not accessible to consumers
• Records that re-populate from public records after opt-out
• Records in databases that don’t offer opt-out mechanisms

This distinction is important: removing your profile from BeenVerified doesn’t remove the underlying court record, property record, or business filing that fed that profile. Anyone who searches official government sources directly will still find that information. Data broker opt-outs remove the aggregated commercial profile — not the underlying public record.

Privacy Implications for Individuals

The data broker ecosystem has several significant privacy implications that most people don’t consider until they’ve been affected.

Information created through routine activities is commercialized. Buying a home, forming a business, appearing in any court proceeding, or registering to vote creates records that flow into commercial databases without your knowledge or consent. This is a feature of public records law — transparency — that has commercial consequences most people didn’t anticipate when those records were created.

Inaccurate information can affect real decisions. Data broker profiles are used for identity verification, fraud detection, and preliminary screening. Inaccurate profiles — wrong addresses, merged records from someone with the same name, outdated employment information — can produce false fraud flags, verification failures, or incorrect background check inputs.

The opt-out process is ongoing, not permanent. As new public records are created and new data sources are added, data broker profiles are regularly updated. A profile removed today may be partially re-populated within months as new address information, court filings, or other data becomes available.

Professional investigative databases are not accessible to consumers. The most detailed data broker platforms — LexisNexis Accurint, TLO, CLEAR — are not accessible through consumer opt-out processes. Individuals cannot view or request removal from these databases, which are restricted to licensed professionals.

Common Mistakes About Data Brokers

Assuming data broker profiles are complete and accurate. Data broker profiles are aggregated estimates, not verified records. They are built by automated systems that make probabilistic connections — and those systems make regular errors. Never treat a data broker result as authoritative without verification through the originating government source.

Thinking one opt-out removes all your data. Hundreds of data broker services operate independently. Opting out of BeenVerified removes your profile from BeenVerified — it has no effect on Spokeo, Intelius, Whitepages, or any other service. Comprehensive removal requires submitting requests to each service individually or using an automated tool.

Confusing data broker opt-outs with public records removal. Removing a commercial data broker profile does not remove the underlying public record. Court filings, property records, and business registrations remain in official government systems regardless of whether a commercial data broker has removed your profile.

Assuming professional databases are the same as consumer tools. LexisNexis, TLO, and CLEAR provide significantly more comprehensive and more current data than consumer people-search tools — and they are not accessible through the same opt-out processes. Their data quality and coverage are not comparable to BeenVerified or Spokeo.

Using data broker reports for formal screening decisions. Consumer people-search tools explicitly prohibit their use for employment, housing, or credit decisions. This prohibition exists regardless of how accurate a specific report may be in a particular case.

Frequently Asked Questions

Are data brokers legal? Yes. Data brokers operate legally in the United States, though their activities are increasingly regulated. The FCRA governs brokers that provide consumer reports for formal screening. The CCPA gives California residents rights over their data. Vermont requires data broker registration. Federal and state regulation of the industry is expanding.

Do data brokers have Social Security numbers? Some data broker systems — particularly professional investigative platforms used by licensed investigators and financial institutions — process SSN-derived data for identity verification purposes. Consumer-facing people-search tools generally do not display full Social Security numbers. The DPPA and other laws restrict certain uses of SSN and DMV data.

Can I find out what data brokers have about me? For consumer-facing services, you can search your own name on each platform. California residents can exercise CCPA access rights to request disclosure from companies operating in California. For professional investigative databases, consumer access is not available.

Why is my information still showing up after I opted out? Data broker profiles are regularly re-populated as new public records and data sources become available. An opt-out removes your current profile — it doesn’t prevent future profile creation from new data. This is why automated opt-out services that perform quarterly re-scans are more effective than one-time opt-out requests.

How are data brokers different from background check services? Data brokers compile and sell personal data for various purposes including marketing and informational research. FCRA-compliant Consumer Reporting Agencies compile consumer reports specifically for employment, housing, and credit screening — and are subject to strict requirements including written consent and adverse action procedures. Many people-search services are data brokers, not CRAs.

Final Thoughts

Data brokers are the commercial infrastructure behind the people-search industry — the companies that collect information from public records and other sources, aggregate it into searchable profiles, and sell access to businesses and individuals. Understanding how they work explains both why people-search tools exist and why their results are often inaccurate.

For investigators, data broker databases are useful lead-generation tools — not authoritative sources. Every significant finding needs verification through official government records.

For individuals concerned about their own profiles, the most effective approach is a combination of opt-out requests to major consumer services and an automated removal tool for ongoing coverage — with the understanding that underlying public records cannot be removed, only the commercial profiles built from them.
