Quick answer
When a debt collector first contacts you, it generally must provide validation information — who the creditor is, what the debt is, an itemization of the amount, and the end date of a 30-day period in which you can dispute it. If you dispute the debt in writing within that window, or ask for the original creditor’s name and address, the collector must pause collection of the disputed amount until it sends you verification. This is not a credit report dispute: validating a debt does not by itself correct anything on your credit report, and a report dispute does not by itself stop collection activity. You can use both, for different purposes.
Who this letter is for
This letter is for someone a debt collector has contacted — ideally within 30 days of receiving the collector’s validation notice, though you may dispute a debt in writing at any time. It suits anyone who does not recognize the debt, thinks the amount is wrong, believes it was already paid or settled, suspects it belongs to someone else, or simply wants the details in writing before responding to anything. Asking for validation is not an admission that the debt is yours, and it is not a payment arrangement.
When this letter may be appropriate
- A collector has contacted you about a debt you do not recognize
- You are within the 30-day window shown on the collector’s validation notice
- The amount looks wrong, or has grown in a way you cannot account for
- You believe the debt was already paid, settled, or discharged in bankruptcy
- You want the name and address of the original creditor, which may differ from the collector
- Several collectors appear to be contacting you about the same underlying debt
- You want everything in writing before you discuss payment with anyone
When this letter is not appropriate
- You want to correct how something appears on your credit report — that is a dispute, not validation
- You already know the debt is yours, the amount is right, and you simply want it removed
- You are using it as a delay tactic on a debt you know you owe
- The account is the result of identity theft — start at IdentityTheft.gov, which opens faster protections
- You have been served with a lawsuit — a court deadline is not a validation matter; speak with an attorney promptly

Documents you may need
You generally do not need to prove anything to request validation — the request itself is your right. Still, gather what you have, because it shapes what you ask for:
- The collector’s validation notice or first written communication, including the date you received it
- Any voicemail log, letter, or email from the collector, with dates
- Records of any payment, settlement, or payoff on the underlying debt
- Bankruptcy schedules and discharge order, if the debt was included
- Your credit reports, so you can see how — and by whom — the debt is being reported
- Notes on which collector contacted you when, if there has been more than one
Keep your originals; send copies. Nothing you mail comes back. Photocopy or scan every document, send the copy, and file the original where you can find it again — if an item reappears months later, that file is your entire case.
A note on identifying information: recipients sometimes ask for proof of identity and address. Provide only what the recipient asks for, only in your mailed or securely uploaded letter, and never publish or type a full Social Security number into any web page — including this one. This site does not collect, transmit, store, or pre-fill any of your information.
