Read the validation notice before you answer a collector

Last reviewed October 1, 2026 · 15 minutes

Who this is for. Adults in the United States who have a letter or email from a debt collector and have not yet paid it or agreed to a debit.
Who should skip this. Anyone with a summons or complaint — that is a court deadline, not this letter. Anyone whose account is only late with the original company and no collector has written.

This page does not say the debt is not yours. It says: read the notice, then use an official letter if you need one. A chatbot draft is not that letter.


The method in one paragraph

Find the validation notice. Check that it names the collector, the creditor, an itemization, the current amount, and an end date for a 30-day period. If you do not recognize the debt or the amount looks wrong, dispute in writing before that date, using the tear-off on the notice or a CFPB sample letter. A written dispute inside the period requires the collector to pause collection of the disputed part until they send verification. Asking them to stop calling does not erase the debt. If the paper is a summons, leave this page.


For you if…


Not for you if…


Steps

  1. Write: collector name; creditor named; current amount; end date of the 30-day period printed on the notice.
  2. If any of those are missing, do not pay on the first call. CFPB says you can complain if the validation information was not provided.
  3. If you do not recognize it, or the amount looks wrong: use the tear-off, or the CFPB sample for “I do not owe this” / “I need more information.” Send it so it arrives before the date on the notice. Keep a copy.
  4. If you only want calls to stop: the CFPB stop-contact letter does that. You may still owe the debt. They may still sue.
  5. Do not send a Social Security number, a photo of your license, or a bank login to get them to “verify.”

What the 30 days is, and is not

Under the CFPB’s Debt Collection Rule, the validation period runs until 30 days after you receive, or are assumed to receive, the validation information. The notice should state the date the collector will treat as the end. A written dispute on or before that date pauses collection of the disputed portion until verification or a copy of a judgment is sent. Missing the date does not prove the debt is yours. It does mean you lost that pause. An oral “I dispute” on a call is not the written notice this rule describes.


What can go wrong


Next action

One notice. Four lines. One official letter only if the amount or the creditor is wrong, or you want contact to stop. Then stop.
