The 6 Types of Identity Theft — And How Each One Works
When most people think of identity theft, they picture a stolen credit card or a hacked bank account. And while financial identity theft is the most common type, it’s far from the only one. There are six distinct categories of identity theft, and each works differently, targets different parts of your life, and requires a different response if you become a victim.
Understanding which type of identity theft you’re dealing with is the essential first step to knowing what to do next. Here is a complete breakdown of all six types.
—
1. Financial Identity Theft
What it is: The most common form of identity theft. A thief uses your personal information — typically your Social Security number, date of birth, and name — to open new lines of credit, take out loans, open bank accounts, or access existing accounts.
How it happens: Most often through data breaches, phishing, or stolen physical documents. A thief purchases your data on the dark web and begins applying for credit cards, auto loans, or personal loans in your name.
How you’ll know: Unexpected bills, collection calls for accounts you don’t recognize, hard inquiries on your credit report from lenders you’ve never contacted, or a sudden drop in your credit score.
What to do: Freeze your credit at all three bureaus immediately. Report to the FTC at IdentityTheft.gov. File disputes with each creditor. File a police report.
How to protect yourself: Credit freezes, fraud alerts, strong password hygiene, and regular credit report monitoring are your primary defenses.

2. Medical Identity Theft
What it is: Someone uses your name and health insurance information to receive medical care, fill prescriptions, or submit fraudulent insurance claims — all billed to your insurer.
How it happens: Often through healthcare data breaches, stolen insurance cards, or corrupt healthcare employees. Your insurance ID and member number are sometimes enough.
How you’ll know: Explanation of Benefits (EOB) documents for care you didn’t receive, medical bills for services you don’t remember, or discovering inaccurate information in your medical records — wrong blood type, medications you’ve never taken, conditions you don’t have.
Why it’s particularly dangerous: Unlike financial identity theft, medical identity theft doesn’t just cost you money — it corrupts your medical record. Incorrect information in your file can affect the care you receive in an emergency.
What to do: Contact your insurer’s fraud department, request a complete copy of your medical records, and file a report with the FTC. The process of correcting medical records is more complex than correcting credit records.

3. Criminal Identity Theft
What it is: Someone gives your name and personal information to law enforcement when they are arrested, cited, or investigated for a crime. A warrant for your arrest may be issued without you ever knowing a crime was committed in your name.
How it happens: Often by people who know your personal details — an acquaintance, a family member, or someone who stole your wallet or ID. It can also happen with entirely fabricated documents.
How you’ll know: You are stopped by police and informed of an outstanding warrant. You fail a background check for a job you applied for. Your record shows an arrest or conviction you know nothing about.
Why it’s devastating: A criminal record in your name doesn’t just affect your finances — it can cost you jobs, housing, professional licenses, and your freedom.
What to do: Contact the arresting jurisdiction to explain the situation and begin the process of clearing your record. You may need an attorney. The path typically involves proving your whereabouts and identity at the time of the alleged offense.

4. Tax Identity Theft
What it is: A thief uses your Social Security number to file a tax return in your name and collect your refund before you file. By the time you sit down to do your taxes, the refund is already gone.
How it happens: Tax season is prime time for identity theft. Thieves purchase SSNs and file fraudulent returns early in the season, before victims file legitimate returns. The IRS has improved its detection significantly, but billions of dollars in fraudulent refunds are still issued each year.
How you’ll know: Your electronic tax return is rejected with a message that a return has already been filed under your Social Security number.
What to do: File IRS Form 14039 (Identity Theft Affidavit) immediately. File a paper return. Report to the FTC. The IRS will assign you an IP PIN (Identity Protection PIN) to use on all future returns, which prevents anyone else from filing under your SSN.

5. Employment Identity Theft
What it is: Someone uses your Social Security number and personal information to get a job. Their wages are then recorded under your SSN with the Social Security Administration.
How it happens: Often by undocumented workers using purchased SSNs, or by individuals trying to avoid wage garnishments or hide criminal records. The theft can go undetected for years.
How you’ll know: You receive a W-2 or 1099 from a company you’ve never worked for. Your Social Security earnings statement shows income from employers you don’t recognize. You receive tax bills for income you never earned. You’re denied employment benefits because your record shows employment that disqualifies you.
What to do: Contact the SSA to review your earnings record. File a report with the FTC and the SSA’s Office of the Inspector General. Contact the employer listed on the fraudulent W-2. The IRS may also be involved if taxes were not properly withheld.

6. Child Identity Theft
What it is: A thief uses a child’s Social Security number — which is assigned at birth and has a completely clean credit history — to open accounts, apply for loans, or establish a false identity. Because children don’t monitor their credit or apply for it themselves, the theft can go entirely undetected for a decade or more.
How it happens: Children’s SSNs are valuable precisely because they’re clean. They’re often stolen from healthcare records, school databases, or government documents. In some cases, the thief is a family member or trusted adult.
How you’ll know: Your child attempts to apply for their first credit card, student loan, or job and discovers they already have a credit history — one that doesn’t belong to them.
Prevention is especially important: Parents and guardians can freeze a child’s credit proactively, which blocks any new credit from being opened in their name until the freeze is lifted.

Which Type of Identity Theft Is Most Common?
According to the FTC’s 2023 Consumer Sentinel data:
- Credit card fraud — most frequently reported type of identity theft
- Government documents and benefits fraud — including tax and unemployment fraud
- Loan or lease fraud
- Bank fraud
- Employment or tax-related fraud
Financial identity theft dominates by volume. But medical, criminal, and child identity theft tend to be the most difficult to detect and recover from — making early awareness especially valuable.

How to Protect Yourself From All Types
Regardless of which type you’re concerned about, three actions protect against nearly all of them:
Freeze your credit. A credit freeze blocks new credit from being opened in your name and is the single most effective preventive measure against financial, employment, and child identity theft.
Review your records regularly. Pull your credit report at AnnualCreditReport.com. Review your SSA earnings record annually at SSA.gov. Check your medical records once a year with major providers.
Protect your Social Security number. Your SSN is the master key to most forms of identity theft. Never carry your Social Security card. Question any request for your SSN and provide it only when it’s legally required.
