Relentless collector calls feel like harassment because, sometimes, they legally are. The good news: the Fair Debt Collection Practices Act and the CFPB's newer call-frequency rules give you concrete, enforceable control. Below are the steps in the order that protects you fastest, ending with the only thing that makes the calls stop permanently: resolving the debt. This is legal-adjacent information, not legal advice.
Know your FDCPA rights
The FDCPA governs third-party debt collectors, the agencies and buyers who collect on someone else's behalf. Knowing these rights is the leverage behind every step that follows. At a glance, a collector:
- Must validate the debt on request. Ask in writing and they have to send proof of the amount and the original creditor before pressing you to pay.
- Generally cannot call you more than 7 times in 7 days about one debt. This is the CFPB's Regulation F "7-in-7" rule, and it counts calls per debt, not per day.
- Cannot call at unreasonable hours — generally before 8 a.m. or after 9 p.m. your local time.
- Cannot threaten arrest, claim to be an attorney, or inflate what you owe. Not paying a consumer debt is not a crime, and they cannot pretend otherwise.
- Cannot keep contacting you at work once you tell them your employer prohibits such calls, and they cannot reveal your debt to your boss or coworkers.
Honest caveat: a cease-communication letter stops the calls, but it does not erase the debt — and it can prompt the creditor or collector to sue you instead, since contacting you is one of their remaining options once the phone goes quiet. Use it deliberately, and always request validation first so you have a paper trail and know exactly what you are dealing with.
Send a written "stop contact" request (and keep proof)
You can send the collector a written letter stating you want all contact to stop. Once they receive it, they generally must stop reaching out, except to confirm they will stop or to notify you of a specific action such as a lawsuit. Send it by mail with tracking, or keep a dated copy and delivery confirmation. Proof of delivery is what makes the request enforceable, so document everything.
What collectors legally cannot do
Collectors cannot harass you with repeated or abusive calls, use threats or obscene language, or make false statements, like claiming to be an attorney, threatening arrest, or inflating the amount. The CFPB's Regulation F (2021) caps call frequency at generally no more than seven calls within a seven-day period per debt. If a collector crosses these lines, note the date, time, and what was said, you can report it to the CFPB.
Validate the debt before you pay anything
Never pay on a call alone. Request written validation: the amount, the original creditor, and proof the debt is yours. Debts get sold, duplicated, and misattributed, and some are past the statute of limitations. If the details don't check out, dispute it in writing. Validation also creates a paper trail that protects you if the debt later turns into a lawsuit.
Free tools and where to complain
You do not need to pay anyone to enforce your rights — the federal government and nonprofit experts publish the tools for free. Use them:
- Free sample letters from the CFPB. The Consumer Financial Protection Bureau hosts ready-to-use templates, including a debt-validation request and a letter telling a collector to stop contacting you. You fill them in and send them yourself, at no cost (consumerfinance.gov).
- File a complaint with the CFPB if a collector breaks the rules — it forwards the complaint to the company and tracks the response (consumerfinance.gov/complaint).
- Report harassment to the FTC at reportfraud.ftc.gov, which feeds a database law enforcement uses against abusive collectors.
- Contact your state attorney general. Most states accept consumer complaints and enforce their own debt-collection laws, which sometimes go further than federal rules.
- Read up on your rights through the National Consumer Law Center, which explains the FDCPA in plain language (nclc.org).
Keep dated notes of every call and a copy of every letter. That record is what turns a complaint into an enforceable one.
Resolve the underlying debt (the lasting fix)
A stop-contact letter quiets the phone, but it doesn't erase what's owed, an unresolved balance can still be sued on or reported. The permanent fix is to resolve the debt: a payment plan, or for unsecured balances of roughly $7,500 or more, a negotiated settlement that pays less than the full amount. Settlement has trade-offs, it can affect your credit and may have tax consequences, so weigh it against your other options. Once the debt is settled and documented, the calls stop for good.
