It can include obvious details such as a name or Social Security number, as well as financial, health, employment, location, or online data. Whether a particular data point counts as PII depends on context and the applicable law or policy.
What counts as PII?
A useful test is: could someone use this information, alone or with other available information, to identify or distinguish a particular person? A name or account number may identify someone directly. A date of birth, ZIP code, or device identifier may become identifying when combined with other data.
There is no single universal legal definition of PII. NIST Special Publication 800-122 offers guidance for information maintained by agencies; it is not a definition that automatically governs every private business or jurisdiction. Other laws use terms such as “personal data” or “personal information” and define their scope differently.
Types and examples of PII
PII appears in many kinds of records, not just identity documents. Whether a particular item identifies someone depends on how specific it is and what other information can be linked to it.

| Category | Examples | Context to consider |
|---|---|---|
| Identity and government identifiers | Name, date or place of birth, Social Security number, passport or driver’s-license number, taxpayer ID | A sufficiently specific name or government ID may identify a person directly. |
| Contact and location | Address, email, telephone number, precise location, location history | Contact details and location data may identify or distinguish someone, depending on their linkability. |
| Financial and payment | Bank or card number, credentials, credit report, transactions, loan information | Credentials and account data may create direct access or fraud risks; transaction records can reveal behavior. |
| Health and medical | Diagnosis, prescription, insurance or patient number, lab results | Health information linked to a person can be PII. HIPAA’s protected health information (PHI) is a specific category with defined scope, not a synonym for all PII. |
| Biometric and genetic | Fingerprint, voiceprint, facial geometry, iris scan, DNA results | These may identify a person and can be difficult to change if compromised. |
| Education and employment | Student ID, grades, employment history, payroll, benefits, work credentials | Records may identify a person directly or through combination with other details. |
| Online, device, and behavioral | IP address, cookie or advertising ID, device fingerprint, browsing history, app activity | Status depends on whether the data can reasonably be linked to or distinguish a person. |
Direct identifiers and indirect identifiers
A direct identifier can identify someone without much additional information. Examples can include a Social Security number, passport number, patient ID, account number, or a sufficiently specific name. Email addresses, phone numbers, and biometrics may also function as direct identifiers depending on context.
Indirect identifiers, sometimes called quasi-identifiers, may not identify someone by themselves but can do so in combination. Examples include age, date of birth, ZIP code, employer, job title, school, device identifiers, and activity logs. NIST distinguishes information already associated with a person from information that could be linked to them using another system, public record, or online source.
For example, a list of credit scores without names or linkable identifiers may not identify particular people. Adding names, addresses, dates of birth, or other information can make the records identifiable. Removing direct identifiers does not necessarily prevent re-identification.

PII, personal data, and sensitive information
“PII” is commonly used in U.S. information-security and privacy contexts. “Personal data” is the term used in the GDPR and UK GDPR for information relating to an identified or identifiable natural person. These terms are related, but they are not legally interchangeable in every jurisdiction.
Recommended Free Tools
Sensitive PII is not one universally defined category. Laws and organizations may treat government ID numbers, account credentials, financial and health records, biometrics, genetic information, and precise geolocation as higher risk. NIST recommends assessing the potential harm from unauthorized access, use, or disclosure rather than assuming every PII element has the same risk.
An IP address, cookie ID, or device identifier is not automatically PII in every circumstance, but it may qualify when it can reasonably be linked to or distinguish a person. Similarly, encryption is a security measure; it does not necessarily make information cease to be personal information. Pseudonymized data, such as records using a customer code instead of a name, can remain identifiable if re-identification is reasonably possible. Proper anonymization is different: the person is no longer reasonably identifiable.

Examples of PII in everyday records
- Job application: name, contact details, employment history, date of birth, and government ID.
- Medical claim: patient name, health-plan number, diagnosis, treatment date, provider, and billing information.
- Online account: username, email, IP address, device identifier, login credentials, and activity history.
- School record: student name and ID, grades, disciplinary history, and parent contact information.
- Bank statement: name, address, account information, transaction history, and payment details.
PII can appear in paper records, images, audio, video, metadata, and digital files. Its format—including an encrypted format—does not by itself determine whether it is identifiable.
What may not be PII?
Information about people is not automatically PII if it cannot identify, distinguish, or reasonably be linked to an individual. Examples may include aggregate statistics, general demographic totals, or properly anonymized records. Information about a business, rather than an identifiable natural person, may also fall outside a particular definition.

Why PII matters
Unauthorized access, use, or disclosure of PII can lead to identity theft, fraudulent account opening, tax or employment fraud, medical identity theft, financial loss, discrimination, blackmail, reputational harm, or physical safety risks. The Federal Trade Commission describes identity theft as using someone’s personal or financial information without permission, including to open accounts, obtain services, file a tax return, or impersonate the person.
Financial organizations use PII for account opening, transactions, credit decisions, fraud prevention, and recordkeeping. Collecting and retaining it also creates responsibilities to limit access, protect it, and follow applicable legal requirements. The relevant duties depend on the organization, information, and jurisdiction; no single PII rule applies everywhere.

- Consider identifiability: determine whether the data identifies, distinguishes, or traces someone on its own.
- Check what can be linked: consider other data, systems, public records, and technical identifiers that could be joined to it.
- Assess sensitivity and potential harm: consider what could happen if the data were accessed or disclosed without authorization.
- Limit collection and access: keep only what is needed for a defined purpose and restrict access to people who need it.
- Use appropriate safeguards: organizations should apply security controls and retention practices suited to the data and applicable requirements. Consumers can use unique passwords and multi-factor authentication, and review financial accounts for unfamiliar activity.
FAQ
Is an IP address PII?
It can be. An IP address may qualify when it can reasonably be linked to or used to distinguish a person, but its status depends on context and the applicable law.

Does encryption remove PII status?
Not necessarily. Encryption protects information from unauthorized access, but encrypted data can still be personal information. Encryption is not the same as anonymization.
Does hashing or replacing a name anonymize data?
Not automatically. A hash, token, or customer code may remain linkable or allow re-identification when combined with other information. Pseudonymized data can still be personal data under applicable rules.
Is all health information protected by HIPAA?
No. HIPAA’s PHI rules apply to specified covered entities and business associates and include defined exclusions. Health information outside that framework may be covered by other laws or policies, but it is not automatically HIPAA PHI.
Is there one official list of PII that applies everywhere?
No. Definitions vary by jurisdiction, law, regulator, contract, or organization. Assess whether data is identifiable in context and check the rules that apply to the organization and information involved.
