Korea warns of “relay” phone scams that start with a fake community centre call

South Korea’s Financial Supervisory Service (FSS) issued a consumer alert at the “Caution” level on November 12, 2026 about a voice phishing scheme it calls “relay institution impersonation”. The first call claims to come from a local community service centre. By the end, the victim has heard from what seem to be five different institutions, and every one of them was the same criminal group. Yonhap and The Asia Business Daily reported the alert. The script is specific to Korea, but the trick works anywhere.

How the scam works

The FSS describes four stages: bait, a relay of fake institutions, fear and isolation, and taking the money. In one case last month, according to Yonhap:

1. The bait. A caller posing as a community service centre employee said someone had come in with the victim’s ID card and a power of attorney to collect copies of their resident registration.
2. The relay. Worried about identity theft, the victim was steered into calling numbers the scammers supplied. People claiming to be from the Korea Credit Information Services, the FSS and the prosecution service then called in turn, saying the victim’s identity had been used in a crime and their assets needed to be “inspected”.
3. Fear and isolation. The callers told the victim not to tell anyone.
4. The money. Finally someone posing as a bank branch manager convinced the victim that the state would look after their assets. Over three days, the victim handed over 100 million won.

The FSS says the scammers make victims feel they’re being protected from a crime, not questioned, which lowers their guard. And because the victim dials the number themselves, it feels safer. “From the moment you call the number you were given, everyone on the line is a fraudster,” the FSS said, as quoted by The Asia Business Daily.

The FSS adds that the opening line changes. Besides community centres, scammers use court mail, parcel deliveries and card deliveries as bait. The structure stays the same: get the victim to call a number or follow a link the scammer supplied, then impersonate an institution and ask for money.

What the FSS is doing

The FSS says it is sharing the details with the whole financial sector through its voice phishing prevention meetings, and will guide banks to watch for warning signs at branch counters and in fraud detection systems, such as early termination of large deposits and split transfers to several accounts.

What you can do

1. Never call a number a caller gives you. Hang up and look up the institution’s number yourself. In Korea, the FSS points people to the government call centre at 110 to check whether anyone really tried to get documents in their name.
2. Check for identity theft yourself. The FSS says the Korea Credit Information Services doesn’t take identity theft reports at all, and suggests checking for yourself whether your identity has been misused or a phone line opened in your name, through the AccountInfo service.
3. No agency will ask you to move money. The FSS, prosecutors, the Serious Crimes Investigation Agency and the police never ask you to send money for any reason.
4. “Don’t tell anyone” is a warning sign. Tell your family and the police straight away.
5. Outside Korea, the same rules apply. Whether the caller says they’re the bank, the police or a government office, hang up and call back on a number you found yourself.

How Frame helps

Scams like this often start with details that are already circulating, such as your name, phone number or ID details from an old leak. Frame can also look up your verified emails in Have I Been Pwned’s breach database so you can see which of your addresses have appeared in known leaks, and Frame’s checklists explain what each leak exposed. Frame never collects or stores the leaked records themselves.
