What “Selling Personal Data” Means in Law
In U.S. privacy law, “selling data” does not always mean a direct exchange of money.
Depending on the law, it may include:
- Sharing personal information with third parties
- Transferring data for advertising or marketing
- Providing access to data in exchange for business benefits
“Personal data” can include:
- Names and contact information
- Online identifiers (IP address, device IDs)
- Location data
- Purchase or browsing history
- Biometric identifiers in certain cases
Different laws define these terms differently. There is no single definition that applies nationwide.
No Single Federal Privacy Law
The United States does not currently have one comprehensive federal law that governs all personal data collection and sales across all industries.
Instead, privacy regulation is structured through:
- Federal laws that apply to specific sectors
- State laws that apply more broadly to consumers
- Federal enforcement authority through agencies like the Federal Trade Commission (FTC)
Because of this structure, whether selling data is legal depends on the situation.
Federal Laws That Limit Data Use
Certain categories of data are protected under federal law.
These laws do not ban all data sales, but they impose strict requirements.
Health Information
- Governed by HIPAA
- Applies to covered entities and business associates
- Limits how protected health information can be used or disclosed
Financial Information
- Governed by the Gramm-Leach-Bliley Act (GLBA)
- Requires financial institutions to explain data-sharing practices
- May require providing opt-out rights
Children’s Data
- Governed by COPPA
- Applies to children under age 13
- Requires notice and verifiable parental consent in covered situations
Each law applies only within its defined scope. Outside those areas, other rules may apply.
FTC Authority and Unfair Practices
The FTC enforces consumer protection laws related to privacy and data security.
Companies may face enforcement if they:
- Misrepresent how they use personal data
- Fail to follow their own privacy policies
- Engage in unfair or deceptive practices
This means that even if data sharing is allowed, it must be:
- Clearly disclosed
- Not misleading
- Consistent with public statements
State Privacy Laws Are Expanding
Many states have enacted comprehensive consumer privacy laws.
While these laws vary, they commonly provide rights such as:
- The right to know what data is collected
- The right to request deletion
- The right to correct inaccuracies
- The right to opt out of certain data sales or sharing
These laws generally apply to businesses that meet certain thresholds, such as revenue or data volume.
Not every business is covered in every state.
Illinois Law and Biometric Data
Illinois has specific protections for biometric information.
Biometric identifiers may include:
- Fingerprints
- Voiceprints
- Scans of face geometry
Under Illinois law, private entities must:
- Provide written notice before collection
- Explain the purpose of use
- Obtain a written release in applicable situations
Failure to follow these requirements can result in legal claims.
When Selling Data May Be Lawful
Selling or sharing personal data may be lawful when:
- The practice is clearly disclosed
- The company follows applicable federal and state laws
- Required notices are provided
- Required consumer rights are honored
However, legality depends on the specific facts and applicable law.
When It May Become Unlawful
Data practices may become unlawful if a company:
- Provides false or misleading disclosures
- Fails to follow its own privacy policy
- Ignores required consumer rights
- Mishandles protected categories of data
- Fails to implement reasonable data security
Regulators evaluate these situations case by case.
Consent Depends on the Law
There is no single universal consent standard in U.S. privacy law.
Instead:
- Some laws require affirmative consent
- Some require notice and opt-out options
- Some do not require consent for certain uses
The requirements depend on:
- The type of data
- The law that applies
- The role of the company handling the data
Data Brokers and Disclosure Requirements
Data brokers collect and share personal information from multiple sources.
Their activities may be lawful if they:
- Comply with applicable state laws
- Provide required disclosures
- Honor consumer rights where required
However, obligations vary by jurisdiction.
Your Right to Opt Out
Some state laws give consumers the right to opt out of certain data sales or sharing.
Where applicable, businesses must:
- Provide a clear method to submit requests
- Process requests within required timeframes
These rights are not identical across all states.
Online Terms and Privacy Policies
When using websites or apps, users often agree to privacy policies.
These policies must:
- Accurately describe data practices
- Not be deceptive
- Align with actual business practices
If a company states one thing but does another, that may trigger enforcement.

Can Businesses Sell Customer Data
Businesses may share or sell data only if they comply with applicable law.
This typically requires:
- Transparent privacy disclosures
- Compliance with federal and state requirements
- Procedures to respond to consumer requests
Businesses should not assume that general permission exists.
Each situation must be evaluated under the relevant law.
Key Risk Areas for Businesses
Common areas where legal issues arise include:
- Marketing databases
- Website tracking technologies
- Third-party data sharing agreements
- Customer account information
- Analytics and advertising tools
Risks increase when practices are not clearly documented or disclosed.
How This Affects Individuals
Consumers may be affected by data sharing in several ways:
- Increased targeted advertising
- Profiling based on behavior

Understanding applicable rights can help reduce these risks.
Where Privacy Law Is Heading
