There is a specific reason foreign residents are approached for this more often than Korean nationals. Someone who needs a name that is not their own prefers a name attached to a person who may not be in the country next year, who is less likely to understand the paperwork, and who is less likely to go to the police when it unravels.
The arrangements differ but the structure does not. Your identity carries the obligation; the other person carries the benefit.
1A Bank Account — the Most Dangerous One
Handing over a bank card, passbook, or online banking credentials is not a neutral act in Korean law. Transferring or lending the means of access to an account is prohibited in itself, with criminal penalties attached, and it does not require the account to have been used for anything.
That is the part people miss. The usual assumption is “if I didn’t know what it was for, I’m fine”. But the lending is the offence, and what the account was then used for — typically fraud proceeds moving through it — is what turns a contained problem into a serious one.
When that happens, three things arrive together:
- The account is frozen, and often every other account you hold, under the procedure for suspected fraud-linked accounts.
- You are investigated as a possible accomplice in the underlying fraud, not merely for lending the account.
- The victims sue you civilly, because your name is the one they can find.
Being paid for it — even a small amount, even framed as a “part-time job” — makes the accomplice argument substantially harder to resist.
2A Business Registration
Registering a business in your name for someone else transfers the legal identity of that business to you. Not the profits — the identity.
That means the tax liability is yours. If the business under-reports, evades, or simply fails, the assessment comes to the registered proprietor. It means the employment obligations are yours, including unpaid wages and social insurance. It means that if the business is used for something illegal, the person on the registration is where the investigation starts.
You do not get to say the profits were his and the debts are also his. You get the debts, because the debts follow the registration.
For a foreign resident there is a second layer. Operating a business generally requires a status of stay that permits it. Being the registered proprietor of a business you are not authorised to run creates an immigration problem entirely separate from the tax one, and immigration problems are the ones that end residence.
3A Phone Line, a Car, a Rental Contract
The same logic runs through the smaller versions.
- A phone line opened in your name and used by someone else is the standard infrastructure of fraud operations. When the line is traced, it is traced to you. Opening lines for payment is treated as participation, not as a job.
- A vehicle registered to you and driven by someone else leaves you with the tickets, the tolls, the tax, and exposure if it is involved in a serious incident. Cars circulating outside their registered ownership are a known problem category and are treated as such.
- A lease signed in your name for someone else’s occupation leaves you owing the rent and the restoration costs, and answering for what happens in the property.
4How It Is Actually Pitched
Nobody says “lend me your identity so I can commit fraud”. The framing is always something else, and the recurring versions are worth recognising because recognition is the entire defence here.
- “It’s just for the tax year, my credit is bad right now.”
- “A remote job — you receive transfers and forward them, we pay a commission.”
- “We’re partners. I’ll run it, you just register it, we split it.”
- “I’ll pay you for each phone line you open, totally legal.”
- “You’re leaving Korea anyway, it costs you nothing.”
The last one is the most misleading. Leaving does not close these files. It converts them into an entry problem, and you find out at immigration.
5If It Has Already Happened
The most consequential period is the first contact from the police, because that is where the line between accomplice and used party is drawn, and it is drawn largely on what you say and what you can show.
What helps: the conversation history showing how it was presented to you, evidence that you received nothing or that what you received was not proportionate to a criminal role, evidence that you tried to stop it once you understood, and a report you made yourself rather than one made about you.
What hurts: payments received, repetition, continuing after the first sign of a problem, and an improvised account at the first interview that later has to be corrected.
Do not attempt to fix it by contacting the other person and asking them to sort it out. That conversation becomes evidence, and it is usually evidence against you.
→The Rule That Covers All of It
- Never transfer bank access to anyone — not a card, not a passbook, not credentials, not for a day.
- Never register a business you will not actually control. If you are not running it, do not be its proprietor.
- Never open a telecom line for someone else. There is no lawful version of being paid per line.
- If money moves through your account for someone else, stop and get advice the same day. Days matter for whether you look like a participant.
- If you have been contacted, get representation before the first interview — not after the statement is signed.
