How to Stop a Debt Collector from Calling

The phone rings four times before lunch, the voicemail names an account from years ago, and the company calling is one nobody recognizes. Arguing on the call feels like the way through, but nothing said out loud gets written down. The written notice and a written reply are what create a record.

Read the validation notice before anything else

The CFPB page on what a collector has to tell you says validation information is generally provided in a written notice sent as the first communication or within five days of it. That page lists what the notice contains: a statement that the sender is a debt collector, the name of the creditor, the account number where there is one, an itemization of the current amount reflecting interest, fees, payments, and credits, and an end date for a 30 day period for disputing it.

Download the sample letter that matches the situation

The CFPB publishes five sample letters as free Word downloads: saying the debt is not yours, asking for more information, asking the collector to stop contacting you, directing it to an attorney, and setting out how you prefer to be contacted. That page notes the letters are not legal advice. It was loading and the files were live as of September 2026.

Dispute the debt inside the 30 day window

The same CFPB validation page states that requesting verification in writing within the 30 day period means the collector has to pause collecting the amount being disputed until it responds. It also says that failing to request verification in writing, or missing that window, can affect the ability to assert rights under the debt collection rule.

Check the calls against the Regulation F limits

The CFPB page on collector phone calls says collectors are generally prohibited from contacting you before 8 a.m. or after 9 p.m. It also says a collector is presumed to violate the law by placing more than seven calls about a particular debt within seven days, or by calling within seven days after a phone conversation about that debt. Those presumptions cover phone calls only, not texts, emails, or social media messages.

Send the letters so there is proof of delivery

The CFPB page on stopping contact suggests keeping a copy, sending the original, and using certified mail with a return receipt as proof. That page also says a collector told to stop may still confirm there will be no further contact and may note that it or the creditor can take other legally available actions, including filing a lawsuit.

If the calls continue anyway. The CFPB complaint form was loading and accepting submissions as of September 2026, and the CFPB process page says companies generally respond in 15 days, with a final response in 60 days in some cases. The FTC debt collection FAQ also points to the FTC fraud reporting site and to a state attorney general, listed at USA.gov.
