A letter arrives about a debt you don’t remember, from a company you’ve never dealt with, for an account you never opened. For a growing number of people, that notice is how they first learn someone used their identity.

Complaints to the Consumer Financial Protection Bureau (CFPB) about attempts to collect a debt not owed rose about 115% above their prior two-year average in 2025, and many of those consumers reported balances they didn’t recognize and suspected identity theft.

Before you panic or pay, it helps to understand why these letters show up and what rights you have.

A collection letter for a debt you do not recognize can be the first sign that someone used your identity.

Why debt collectors contact you about a debt you do not owe

When a charged-off account is sold to a collection agency, the agency receives the original creditor’s application file, including whatever identifiers were used to open it. That contact information is often 90 to 180 days out of date by the time the account changes hands.

Before the first call, the agency runs skip tracing: matching a name, Social Security number (SSN) and past addresses against public records, postal change-of-address data, property and utility records and data-broker files to find the current person behind the account. At bulk volume, each lookup costs the agency pennies.

The agency then contacts you directly, by phone or mail, whether or not you have looked at your credit file.

How fake debt can start with identity theft

The account behind the notice may have been opened with your information pulled from breaches and resold, then approved by an automated check that matched the data to an existing file without confirming that the applicant was you. Opening a new account is the leading form of attempted identity misuse reported to the Identity Theft Resource Center (ITRC), which counted it more often than takeovers of accounts people already held. What happens after is less understood.

Charged-off debts, including fraudulent ones, are sold in bulk portfolios for pennies on the dollar, often with thin supporting paperwork. One fraudulent balance can be sold and resold across several agencies. A debt you dispute and clear with one collector can be repackaged and reappear with another months later.

With medical debt, a bill can sometimes move toward collections before you see every explanation of benefits, insurance update or corrected statement. That is why you should contact the provider and your insurer before paying a collector.

Fake debts can start with stolen personal information and then move from one collection agency to another.

What debt collectors legally have to tell you

Federal law gives you a defined response, and the clock starts at first contact. Under the CFPB’s Regulation F, a collector must send a validation notice describing the debt and your rights in, or within five days of, its first communication with you.

You have 30 days from receiving that notice to dispute the debt in writing under the Fair Debt Collection Practices Act (FDCPA). Dispute inside that window, and the collector must stop collecting until it verifies the debt.

One important note: the FDCPA generally covers third-party debt collectors, not every original creditor. However, credit reporting laws, identity theft protections and state laws may still give you rights.

If the debt came from identity theft, send the collector an FTC Identity Theft Report from IdentityTheft.gov. Also, tell the collector in writing that you dispute the debt, that it resulted from identity theft and that you want it to stop reporting the account to the credit bureaus.

Ask Equifax, Experian and TransUnion for a block under Section 605B of the Fair Credit Reporting Act (FCRA).

With a valid identity theft report and proof of your identity, the bureaus must block the fraudulent item within four business days. A block is harder to reverse than an ordinary dispute, which counts when the same debt can be resold.

The CFPB has said it may expand the meaning of identity theft under Regulation V to cover “coerced debt,” money run up in someone’s name without their consent, including in domestic and elder abuse cases.

What to do before you pay a debt collector

Before you send money or confirm any personal details, slow down and make the collector prove the debt belongs to you.

1) Ask for proof in writing

Do not pay, promise to pay or give out more personal information during the first call. Ask for the validation notice in writing and save every letter, voicemail and call log. Then send a written dispute within 30 days.

2) File an identity theft report if the debt looks fake

If you believe identity theft caused the account, create an FTC Identity Theft Report at IdentityTheft.gov. Send copies to the collector, the original creditor and all three credit bureaus. Also, place a fraud alert or credit freeze with Equifax, Experian and TransUnion, so it becomes harder for someone to open another account in your name.

3) Check medical bills before paying a collector

With medical debt, contact the provider and your insurer before paying a collector. Ask for an itemized bill and an explanation of benefits. A medical bill can end up in collections while paperwork, insurance reviews or billing disputes are still catching up.

4) Respond quickly if a collector sues you

If a collector sues you, do not ignore the papers. Respond by the court deadline or contact a consumer law attorney or legal aid group. Even a debt you do not owe can create bigger problems if you miss a court deadline.

Why early fraud alerts can save you money

Once a fraudulent account charges off and sells, you’re filing several disputes: with the collector, the original lender and the three bureaus, sometimes more than once if the debt is resold. Caught when the account is first reported, it’s one dispute before any of that starts.
