Registered Data Brokers in the United States: 2021

Registered Data Brokers in the United States

Using data available in state data broker registries, this report presents information on 540 unique registered data brokers and their

  • privacy policies
  • practices
  • areas of possible noncompliance


Data brokers are businesses that collect individuals’ personal information and resell or share that information with third parties.1 For more than a decade, privacy and consumer advocates have raised concerns around the largely unregulated industry.2 This is due both to the nature and opacity of the industry. Data brokers rarely have direct contact with the people whose information they collect and share or resell, and people are generally unaware of their existence or data practices.3 The Federal Trade Commission and Government Accountability Office have published reports on the industry,4 and federal legislation has been introduced without success.5

Vermont (in 2018) and California (in 2019) enacted the first laws creating data broker registries to both shine a light on the data broker industry and better enable individuals to exercise privacy rights.6 Vermont’s data broker registration law was introduced in response to the Equifax data breach and went into full effect in 2019.7 California passed the nation’s second registration law in 2019, requiring data brokers to register with the Office of the Attorney General by the end of January 2020.8 Other states—including Maine and New York—have seen unsuccessful legislative efforts to pass similar laws.9

Data Broker Law Overviews


The Vermont statute defines a data broker as “a business, or unit or units of a business, separately or together, that knowingly collects and sells or licenses to third parties the brokered personal information of a consumer with whom the business does not have a direct relationship.”10 Under the statute, a data broker is required to register with the Secretary of State, pay a $100.00 registration fee and provide

  • the name and primary physical, email and internet addresses of the data broker
  • (if the data broker permits a consumer to opt out of the data broker’s collection practices)
    • the method for requesting an opt out
    • the type of opt out (if the opt out applies to only certain activities or sales)
    • whether the data broker permits a consumer to authorize a third party to opt out on a consumer’s behalf
  • a statement specifying
    • the data collection, databases or sales activities from which a consumer may not opt out
    • whether the data broker implements a purchaser credentialing process11
  • any information the data broker has about security breaches it has experienced, including the number of
    • security breaches the data broker has experienced during the prior year
    • consumers affected by the breaches
  • a separate statement detailing the data collection practices, databases, sales activities and opt-out methods that are applicable to minors’ personal information (if the business has actual knowledge that it possesses the brokered personal information of minors)

If a data broker does not comply with the registration requirements, it is subject to a civil penalty of $50.00 per day, not to exceed $10,000 per year for each year it fails to register.


The California statute defines a data broker as “a business that knowingly collects and sells to third parties that personal information of a consumer with whom the business does not have a direct relationship.” California further distinguishes data brokers from the following categories of businesses:

  • a consumer reporting agency to extent that it is covered under the federal Fair Credit Reporting Act12
  • a financial institution to the extent that it is covered under the federal Gramm-Leach-Bliley Act and its implementing regulations13
  • an entity to the extent that it is covered by the California Insurance Information and Privacy Protection Act14

Data brokers are required to pay the registration fee required by the California Attorney General and provide

  • the data broker's name
  • the data broker's primary physical, email and web addresses
  • any additional information or explanation the data broker chooses to provide concerning its data practices

Under the statute, data brokers face penalties of $100 per day for failure to register on time and expenses incurred by the Attorney General‘s office for investigation and prosecution.15


Data Collection and Processing

The first data set—consisting of the data broker registry from the Vermont Secretary of State—was obtained via web scraping during the summer of 2019.

The second data set—consisting of the data broker registries from the California Office of the Attorney General and Vermont Secretary of State—was obtained via direct download (California) and web scraping (Vermont)16 on July 1, 2021.

After compiling data from the two state registries, the data was

  • incorporated with Privacy Rights Clearinghouse's (now archived) Online Data Vendor List—a list of 180 data brokers collected prior to the enactment of the registration laws in Vermont or California
  • scanned to identify and eliminate duplicate entries


Type of Broker Classification

Based on the 2014 Federal Trade Commission report and industry trends, the individual registered data broker’s websites were surveyed and classified into one of four primary service categories*—recognizing that there may be crossover in some areas.19

If the classification was unclear, we classified it as such.



Financial, Fraud Detection, Risk Mitigation

These businesses may compile consumer reports that are used to determine credit worthiness. They may also provide identity verification, fraud detection and risk mitigation services. Some data brokers falling under this category are required to comply with the federal Fair Credit Reporting Act. 


These businesses compile and sell information that relates to a person’s health (e.g. any over-the-counter medications a person has purchased or health-related search history).


These businesses sell products that allow businesses to engage in targeted marketing. They often collect information through online tracking and may sell information such as

  • the types of ads a with which a person interacts
  • the time a person spends on specific websites
  • how a user interacts with a website
  • individual consumer profiles

People Search

These businesses compile personal information—often from public records and social media—to create reports or profiles. They typically allow users to search for specific individuals.


We acknowledge that these categorizations are subjective, and a business may engage in more than one function.

  1. State data broker registries are increasing transparency around businesses that comprise the data broker industry in accordance with their legislative intent. 
  2. After two years of registration requirements, the percentage of registered data brokers providing marketing services increased by 22% while the percentage of those providing people search services declined by 35%.
  3. 25% (135) of the 540 individual data brokers were registered in both California and Vermont—indicating potential noncompliance with registration requirements in both states. 
  4. It is unclear (using publicly available registry data) whether California registrants are complying with yearly registration requirements. 
  5. Data brokers are offering more opt-out options to California residents and residents of other states than they did in 2019 (before the California Consumer Protection Act went into effect).

State Data Broker Registries Increasing Transparency

In 2018, prior to any data broker registration requirements, Privacy Rights Clearinghouse identified 180 possible data brokers through

  • independent research
  • individual complaints submitted to the organization
  • media monitoring over the course of more than a decade

When the Vermont registry data became available in 2019, a total of 238 data brokers were registered with the state.

In July 2021, there were a total of 792 registry entries across both states.

  • 444 in the California registry
  • 348 in the Vermont registry

Accounting for duplicate entries, in July 2021 there were a total of 540 unique businesses registered.

  • 297 only in the California registry
  • 108 only in the Vermont registry
  • 135 in both state registries

Without access to any research that studies or attempts to document the full scope of the data broker industry, it is not possible to comment on the extent to which the 540 unique businesses registered represent the larger industry. However, the increase in registered businesses during this two-year period does indicate the number of registered data brokers more than doubled and the laws are accomplishing the legislative intent of increasing transparency around the industry.

Data Brokers Providing Marketing Increased, People Search Declined

Prior to the 2019 registration requirements, most data brokers identified by Privacy Rights Clearinghouse would have been classified as people search—due, in large part, to their presence in online searches for a person’s name.

In 2019—when analyzed and classified—of the 238 registered data brokers in Vermont

  • 133 were people search (56%)
  • 64 were marketing (27%)
  • 41 were financial, health, other or unclear (17%)

In 2021—when the newly available California and updated Vermont registries were analyzed and classified—of the 540 unique data brokers

  • 113 were people search (21%)
  • 265 were marketing (49%)
  • 162 were financial, health, other or unclear (30%)

While the percentage of registered companies providing people search services declined during the two-year period, the percentage of registered companies providing marketing services increased by almost double.

Potential Noncompliance with Registration Requirements in Both States

Both California and Vermont law apply to businesses that collect personal information on their respective state’s residents—regardless of where the data broker is based or headquartered. In general, the industry is not geographically restricted.

In July 2021, of the 540 unique data brokers

  • 117 reported their primary place of business as a California or Vermont address (22%)
    • 113 in California
    • 4 in Vermont
  • 407 were headquartered in states other than California or Vermont (75%)
  • 16 were headquartered in countries other than the United States (3%)

Overall, the businesses were headquartered in 38 different states and 8 countries.

This demonstrates the need for a more in-depth look into the individual business practices of each data broker to determine the scope of noncompliance among data brokers registered in one state and not another. In the people search context, for instance, this could be accomplished by using the broker’s service to search for residents of the state from which the broker does not have an active registration.

Unclear Whether California Registrants are Complying with Requirements

Under California law, data brokers are required to register annually to maintain compliance, and the state Attorney General’s office is required to keep an updated online registry with the registration information provided.20 This information includes registration status.21

When attempting to analyze how many registered data brokers were up to date on their registrations, information was unclear. The downloadable spreadsheet on the California Attorney General’s website includes a column labeled date added22 (this column is not present in the online registry). It is unknown whether this column indicates the date the data broker registered or the date the data broker was added to the registry by the agency—which may or may not coincide with the date of registration.

If date added indicates the effective date of registration, each data broker’s registration would expire one year after that date23 and approximately 62% (276 of 444) of California registrations would have had an expired status when the data was collected on July 1, 2021. If date added does not reflect the effective date of registration, it is unclear how many businesses are not complying with the renewal requirements.

This could be clarified by

  • defining the date added field
  • adding registration status to the online registry (to indicate whether the business is up to date on its registration)

Data Brokers Offering More Opt-Out Options

In 2019, approximately 39% of data brokers registered in Vermont provided either a form or email for people to opt out of data collection.
In 2020, the California Consumer Privacy Act required data brokers to

  • include a clear and conspicuous Do Not Sell My Personal Information hyperlink on their website's homepage that directs the consumer to a webpage where they may opt out of the sale of their personal information
  • include a description of a consumer’s rights in its online privacy policy or its California-specific description of a consumer’s rights along with a hyperlink to the Do Not Sell My Personal Information webpage
  • refrain from selling the information of consumers who have opted out for twelve months before requesting the consumer to authorize the sale of their personal information
  • only use the personal information collected from the opt-out form to comply with the opt-out request

In July 2021, of the 540 unique data brokers

  • 447 included some form of California-specific opt-out method on their website* (83%)
  • 27 may have had a California-specific method, but either included a broken link to the opt-out webpage or referenced an opt-out right without providing any method of exercising that right (5%)
  • 248 offered an opt-out method for non-California residents (46%)
  • 94 had a vague policy regarding opt-out methods for non-California residents (17%)

This indicates that there has been a change in data broker opt-out options and privacy policies influenced, at least in part, by the California Consumer Privacy Act.


This subset of data brokers did not all have a Do Not Sell My Information hyperlink in a clear or conspicuous place on their website as the law requires. However, they did have a clear section in their privacy policy that directs California consumers to a process where they can opt out or exercise their rights under the California Consumer Privacy Act.
