A call or letter about an old debt can be unsettling. Start by identifying who contacted you. An original creditor is the company you initially owed; a debt collector is a person or company trying to collect the debt. Federal debt-collection rules discussed here generally address debt collectors, not every original creditor. State law may provide more protections.
Review the validation information
A debt collector generally has to give you validation information in its initial communication or within five days after first contacting you. It should identify the creditor, explain the current amount and provide details that help you recognize the account. It also describes how to dispute the debt. Compare it with your own statements and payment records. Do not send sensitive information to an unexpected caller before checking that the business is legitimate.

If the debt looks wrong, note the deadline
If you do not recognize the debt, already paid it, or think the amount is wrong, you can dispute all or part of it. The validation notice states the end of the 30-day period. A written dispute sent within 30 days after receiving the validation information requires the collector to stop collecting the disputed amount until it sends verification. You can also ask in writing, within that period, for the original creditor's name and address if different from the current creditor. That request has its own pause requirement until the information is provided. A dispute is not a guarantee that the debt disappears.

Keep a paper trail
Save the collector's notices, copies of your letters and any proof of payment. Record dates and details of calls. CFPB says certified mail, with a return receipt if you choose to pay for one, can help establish receipt of a written dispute. If you have already paid, seek records from the original creditor if needed. Keep copies, not your only originals.

Watch for debt-relief scams
An unsolicited pitch promising to erase all debt fast, demanding advance payment for settlement services, or asking for personal and financial details is a warning sign. The FTC advises checking reputable credit-counseling services and asking about their fees before signing up. A collector's claim and a debt-relief advertiser's pitch are different things, so verify each independently.

This is general information, not legal advice. If you have been sued or have a deadline other than the validation-notice period, seek local legal help promptly.
Editorial checks: Confirm current federal guidance and any state-law qualification; verify that the cited 30-day period is counted from receipt of validation information, not simply first contact; review debt-collector/original-creditor distinction and FTC advance-fee wording; inspect article for accidental legal guarantees; add an appropriate legal-aid locator or sample letter only after vetting.
