Fake debt collectors: threatening calls about a debt you don't owe

The phone rings and a serious voice tells you that you have an outstanding debt: a loan, an unpaid bill, a fine or an "open court case". They give you a deadline of a few hours, mention seizures, lawsuits or that "the police will come to your home", and offer you one way out: pay right now by instant transfer, mobile payment or card. The problem is that you don't recognise that debt. This is the fake debt collector scam, and it works because it combines two very powerful fears: fear of the law and the shame of owing money. The good news is that checking whether a debt is real is simple, and no genuine debt is collected with rushing, threats and an instant payment app.

How does the fake debt collector scam work?

The scammer introduces themselves as a collection agency, a law firm, a court or even a police officer. There are several common versions:

• The invented debt. They claim you owe a payday loan, a microcredit or an instalment purchase you never signed up for. Sometimes they say it's an old debt "bought" by their company.
• A real debt, but someone else's or already paid. They use data from leaks (name, ID number, address, a company you once had a contract with) to make the claim look believable.
• The fake "court proceedings". They say there's a lawsuit or an arrest warrant and that only paying today will "close" the case.
• Pressure on your circle. They call or message relatives, colleagues or your employer to shame you into paying.

The script almost always combines urgency ("you have until 6 pm"), threats ("seizure", "lawsuit", "arrest", "we'll make it public") and a payment method that's hard to reverse: Bizum (the instant mobile payment system of Spanish banks) or similar apps elsewhere, instant transfers, gift cards or cryptocurrency.

How do I recognise a fake debt collector?

These are the most reliable warning signs:

1. They won't give you the basic information in writing. A legitimate creditor can identify the original creditor, the contract, the date, an itemised amount and exactly which company is making the claim. A fake collector gets nervous or aggressive when you ask.
2. They threaten you with prison or arrest. In Spain, as in most countries, not paying a civil debt doesn't put anyone in prison. And the police don't call people to collect debts.
3. They demand payment on the spot. A real debt can wait while you verify it. Extreme urgency is a tool to stop you thinking.
4. They ask for a mobile payment, gift cards, cryptocurrency or an account in a private individual's name. Serious companies take payments into accounts in their own name and issue a receipt.
5. Courts don't notify people this way. Court communications arrive through formal notification channels, not through a phone call demanding immediate payment.
6. They threaten to tell your family or your employer. Spreading your supposed debt to humiliate you is not a legitimate practice and may be a crime.
7. The number is hidden, foreign or changes with every call. Not conclusive proof, but it adds up.

What are my rights when dealing with a debt collector?

Even if the debt were real, collectors have limits. A collection agency can claim a debt from you, but it can't harass you, threaten you, humiliate you or disclose your situation to third parties. Persistent calls and threats can amount to crimes such as coercion, threats or harassment. In Spain, misuse of your personal data can be reported to the Spanish Data Protection Agency (AEPD); elsewhere, to your national data protection or consumer authority.

You also have the right to:

• Ask for the claim in writing, identifying the creditor and detailing the debt.
• Pay nothing until you've verified it.
• Not have the debt disclosed to the people around you.
• Demand that they stop using your data if you have no contractual relationship with them.

Remember: you are not obliged to confirm any personal data over the phone, whether your ID number, your address or your account number.

What do I do right now if they call?

1. Don't pay anything during the call. Not a portion "to halt the seizure", not "a deposit". Say you'll review it in writing and hang up.
2. Don't confirm any details. Don't give your ID number, address or bank details, and don't acknowledge the debt verbally.
3. Write everything down. Number, date, time, name of the supposed company, amount claimed and what they told you. Save screenshots of texts, emails or WhatsApp messages.
4. Verify it yourself. Look up the official contact of the supposed company or original creditor yourself (never the number they gave you) and ask. Check your bank statements and your contracts.
5. If they mention a bank or a lender, call its official number, the one on your card or on its website. If they talk about a court, consult a lawyer or check your situation through official channels.
6. Block the number once you've collected the information, and don't call back unknown numbers.
7. Warn your family and your workplace if they threatened to contact them: if they know in advance it's a scam, the pressure disappears.

If you receive serious threats or fear for your safety, call 112 (the European emergency number; elsewhere, your local emergency number).

What if I've already paid or given my details?

Don't blame yourself: this scam is designed to frighten. Act fast:

• Call your bank on its official number and explain you've been the victim of fraud. Ask them to try to block or recover the transaction, and change your online banking passwords.
• If you gave card details, block the card from your bank's app.
• If you gave your ID number or personal data, keep an eye on your accounts and on any contracts taken out in your name: they may try to use them to apply for loans.
• Don't pay a second time. If you paid, they'll come back with "a new debt" or "late-payment interest".
• Be wary of anyone offering to recover your money for a fee: it's a second-round scam. More details in how to recover money lost to a phone scam.

Where do I report it?

1. The police. In Spain, the Policía Nacional (091) or the Guardia Civil (062); elsewhere, your national police. File a report with all the evidence: screenshots, numbers, payment receipts and your call log.
2. Your cybersecurity helpline. In Spain, INCIBE's 017, a free and confidential cybersecurity helpline that advises you on what to do and how to protect your data; the OSI (Spain's Internet User Security Office) website has guides and alerts about active scams. Elsewhere, your national cybersecurity agency.
3. The data protection authority (the AEPD in Spain), if a real company processes your data without a legal basis or spreads your supposed debt.
4. Report the number in the spam number directory so other people can recognise it.

Frequently asked questions

They told me my full name and ID number. Doesn't that prove it's real? No. That data circulates in leaks and stolen databases. A stranger knowing your details only proves they have them, not that you owe them money.

Can the police come to my home over a debt? Not because of a call like this. Civil debts are claimed through civil proceedings, with formal notifications and time to defend yourself. Nobody gets arrested for not paying a loan.

What if I really do have an old debt? Then ask for the documentation in writing, check the amount and negotiate with the creditor through its official channels. A real debt doesn't oblige you to accept threats or to pay on the spot.

They keep calling even though I block them. What do I do? Keep your call log as evidence of harassment, report it, and use an app that filters calls from reported numbers, such as NoCall, so they stop reaching you.

In short

A real debt can be checked in writing, is paid into an identifiable account and never comes with threats of prison. If they call you with urgency, fear and an instant payment as the solution: don't pay, don't give your details, verify it yourself and report it. And if you've received one of these calls, report it in the NoCall spam number directory: your warning could save the next person a bad time, and money.
