What Debt Collectors Can and Can't Do: Your FDCPA Rights Explained

Under the Fair Debt Collection Practices Act (FDCPA), a debt collector cannot call before 8 a.m. or after 9 p.m., harass or threaten you, lie about the amount you owe, threaten a lawsuit it does not intend to file, discuss your debt with others, or add unauthorized fees. Within 5 days of first contacting you it must send a written validation notice, and if you dispute the debt in writing within 30 days of receiving that notice, it must stop collecting until it mails you verification (15 U.S.C. § 1692g). The law sets no deadline for the collector to verify; its duty is to pause.

The phone rings. It's a number you don't recognize. On the other end, someone is telling you that you owe money — and they need payment now. They might threaten your credit. They might say they'll sue. They might call your workplace.

Here's what they won't tell you: you have rights. Powerful ones. And most of what they're doing might be illegal.

The Fair Debt Collection Practices Act (FDCPA) is a federal law that protects you from abusive, deceptive, and unfair debt collection practices. Knowing your rights under this law is the single most important thing you can do when dealing with a collector.

What Debt Collectors Cannot Do

The FDCPA draws clear lines. Debt collectors cannot:

  • Call before 8 a.m. or after 9 p.m. in your time zone
  • Call your workplace if you tell them your employer doesn't allow it
  • Harass, threaten, or abuse you — this includes profanity, threats of violence, or calling repeatedly to annoy you
  • Lie about the amount you owe or misrepresent who they are
  • Threaten legal action they don't intend to take — saying "we'll sue" when they have no plans to is a violation
  • Contact you after you send a written cease-and-desist (with limited exceptions)
  • Discuss your debt with anyone other than you, your spouse, or your attorney
  • Add unauthorized fees or interest to the debt

If a collector violates any of these rules, you may be entitled to damages — up to $1,000 per lawsuit (not per violation) under the FDCPA, plus actual damages and attorney's fees.

Your Right to Debt Validation

This is the most important right most people don't know about. Within 5 days of first contacting you, a debt collector must send you a written notice containing:

  • The amount of the debt
  • The name of the creditor
  • A statement that you have 30 days to dispute the debt

If you send a written debt validation request within that 30-day window, the collector must stop all collection activity until they provide verification. That means no calls, no letters — nothing — until they prove the debt is valid and that they have the right to collect it.

Some collectors cannot produce the original documentation; sometimes the amount is wrong, or the statute of limitations has expired.

What a Debt Validation Letter Asks For

A validation request does one job: it disputes the debt under the FDCPA and demands the proof. That means the name of the original creditor, a copy of the original signed agreement, a full accounting of the amount owed with every fee and interest charge, and an itemized list of the underlying charges. BillFighter's Debt Validation Letter demands exactly this. It is free with a BillFighter account, and the letter text never leaves your browser. You print it and send it by certified mail with return receipt.

Certified mail is critical. It creates proof that you disputed in writing, and proof of the date — which is what triggers the collector's duty to stop collecting until it mails you verification. The FDCPA sets no deadline for the collector to reply; its obligation is to pause, not to answer on a schedule.

What Happens If They Can't Validate

The FDCPA (15 U.S.C. § 1692g(b)) says one thing about this point: until the collector mails you verification of the debt, it must keep collection stopped. If it never manages to verify, it can never resume. The law sets no deadline for verifying and doesn't order the collector to close the account; what it does is freeze collection, and that freeze is your leverage.

How to Protect Yourself

  1. Don't acknowledge a debt on the phone — in some states a payment or an acknowledgment can restart the statute of limitations
  2. Communicate in writing only — paper trails protect you
  3. Send everything via certified mail — proof of delivery is your shield
  4. Keep records of every call — date, time, what was said
  5. Know your state's statute of limitations — the lawsuit window closes, and collectors can't sue on a time-barred debt (though some try)

Common questions

What can a debt collector not do under the FDCPA?

A collector cannot call before 8 a.m. or after 9 p.m. in your time zone, call your workplace after you say your employer does not allow it, harass or threaten you, misrepresent the amount or who it is, threaten legal action it does not intend to take, contact you after a written cease-and-desist (with limited exceptions), discuss the debt with anyone other than you, your spouse, or your attorney, or add unauthorized fees or interest.

What is debt validation and how does it work?

Within 5 days of first contacting you, the collector must send a written notice with the amount, the creditor's name, and a statement that you have 30 days to dispute. If you dispute in writing within 30 days of receiving that notice, 15 U.S.C. § 1692g(b) requires the collector to stop all collection activity until it mails you verification.

How long does a collector have to verify the debt?

The FDCPA sets no deadline. Its obligation is to keep collection stopped until it mails verification; if it never verifies, it can never resume. The law does not order the collector to close the account, and it does not set a schedule for a reply.

What can I recover if a collector breaks the law?

The FDCPA allows statutory damages of up to $1,000 per lawsuit (not per violation), plus actual damages and attorney's fees.
