If a debt collector contacts you about an account you do not recognize, or about a balance that looks wrong, you can dispute the debt in writing. You do not need to write an essay or prove that the collector is wrong before asking for verification.
The important part is to act within the period on the collector’s validation notice when possible.
Check the date first
The notice should state the end of the 30-day validation period. For a covered collector, a timely written dispute of all or part of the debt generally requires the collector to stop collecting the disputed amount until it provides verification or a copy of a judgment.
Do not confuse this with a credit report dispute, which follows a different process. And do not confuse it with the deadline to answer a lawsuit. Sending a letter to a collector does not automatically answer a court complaint.
A short letter is enough
I dispute the debt described in your notice. Please provide verification of the debt and the name and address of the original creditor if it differs from the current creditor. Please communicate with me in writing. This is not an acknowledgment that I owe the debt or a promise to pay.
Put your name, return mailing address, the collector’s name and mailing address, the date, and whatever account reference appears on its notice. You do not need to supply your Social Security number, bank account number, or date of birth.

Send it somewhere that counts
Use the address or electronic channel the collector provides for disputes. A mailed letter with tracking or other delivery evidence can help show when it was sent. Save a copy, and keep the proof of mailing and delivery with the original notice.
If you use a collector’s online portal, save screenshots or a PDF of your submission and confirmation. Take care not to click acceptance language that changes your rights without understanding it.
What verification does not mean
A written verification request is not a discovery demand in a lawsuit. Federal validation rules do not necessarily require the collector to send every document you might want, including a complete chain of sale, a signed original contract, or every statement ever issued.
You can still ask for more documents, especially if ownership or the amount remains in question. Whether they must supply particular records depends on the law and the setting. If litigation begins, court procedures become important.
After responding with sufficient verification, the collector may resume collection. A verification letter is a useful first step, not a guarantee the debt will disappear.
