A stranger wants your bank details today, for a debt you've never even heard of. Here's the move: don't pay, don't share a thing, ask who they are, and dispute it in writing. But the last part is the one people get wrong, and it can cost them the protection that actually matters. The fix is boring, it's cheap, and it fits in an envelope. Hold that thought. Step one. No payment, no bank details, no personal information.

Not on this call, however urgent it sounds. Ask for their name, company name, street address and a callback number. A real collector can. Step two. Tell them you'll send a written request and dispute the debt. That's the CFPB's own suggested line. You're using your rights without admitting anything. Step three. Check the validation notice: the creditor, the itemized amount, and your dispute end date.

Step four. Call the original creditor on a number you look up, and pull your credit report at AnnualCreditReport.com. Step five. Not yours, or not sure? Mail a dispute letter within 30 days. Consider certified mail with a return receipt, and keep a copy. Paper beats memory every time. Now the instinct that burns people: I told them on the phone it's not mine, so I'm covered. You're not. The rights that pause collection come from a dispute in writing, within the 30-day window.

Skip that, and the collector will assume the debt is legitimate. Whether it's yours or not. And the jail threat? A real collector shouldn't claim it can have you arrested. That's a scam warning sign. Here's why the letter works: a dispute in writing, within 30 days, forces a pause. They have to pause collecting the disputed amount until they've adequately responded. Not when they feel like it. And the notice itself has to say it's from a debt collector, name the creditor, and itemize the debt.

Here's the part nobody tells you: paying a little to make the calls stop can backfire. On an old, too-old-to-sue debt, any payment, or even a promise to pay, can revive it in some states. What if they demand a prepaid card or money transfer? Scam warning sign. Those payments may be untraceable. Threatening to tell your boss? They generally can't discuss your debt with anyone but you or your spouse.

Calls before 8 a.m., after 9 p.m., or more than 7 in 7 days? Not allowed, unless you agreed. Actually owe it and want to settle? Get a signed letter saying that amount settles the entire debt. And if they actually sue? Don't ignore it. Respond by the date in the court papers. Don't pay on the call, get their details, check the notice, dispute in writing within 30 days. Threats or a suspected scam? Report it to the FTC, the CFPB, or your state attorney general.

Anyone can sound official on the phone. Make them prove it on paper.
