Did a Loan Get Taken Out in Your Name? How to Check and Block New Ones With a Credit Freeze

Why identity theft can reach all the way to a loan

The root of the problem is a financial environment where a resident registration number and a phone verification code are enough to open an account or take out a small loan without visiting a branch. If a copy of an ID card and a text verification code leak, criminals can use them to pull small credit loans from savings banks or lending companies and siphon the money off. Victims often only find out months later, when an overdue-payment notice arrives, by which point they are also stuck with accrued late fees and a damaged credit score. Once collection calls start, proving the loan was fraud requires a police report and a drawn-out dispute with the lender. That is why checking now and blocking it in advance beats reacting after the damage is done.

Check for existing loans first — the Account Information Integrated Management Service

Run by the Korea Financial Telecommunications and Clearings Institute, the Account Information Integrated Management Service (AccountInfo, payinfo.or.kr) lets you view, on a single screen, every account, card, loan, and automatic-transfer registration opened under your name at banks, savings banks, insurers, and mutual finance institutions. It was originally built to help people find and close scattered dormant accounts, but it works just as well for checking whether an account or loan you never opened has appeared under your name. If an unfamiliar loan shows up, contact that financial company's customer center immediately to find out how it happened.

What you need before you check — one certificate is enough

AccountInfo requires identity verification with either a public certificate or a financial certificate when you sign up. Either one works, and phone-app authentication is increasingly accepted as an alternative these days. Checking your accounts only takes one certificate, but if you are worried about identity theft, it is safer to also set up two-factor authentication (2FA) on major accounts like your banking app and email.

Checking isn't enough — how to block new loans at the source

Checking only confirms what has already happened; it does nothing to stop future damage. That's where the Credit Transaction Safe-Blocking Service comes in. The moment you apply, your information is registered with the Korea Credit Information Services, and it blocks any new loan or card issuance under your name in real time across every financial institution — banks, savings banks, card companies, capital firms, insurers, and securities firms. In practice, people lift the block only when they actually need a loan, then reapply it afterward.

Applying is easy, but lifting the block is branch-only

You can apply through the mobile app or online banking of a bank you already use without visiting in person, or bring your ID to a branch if you'd rather not use the app. Lifting the block, however, can only be done by visiting a financial company's branch in person. It may feel inconvenient, but this asymmetry exists specifically to stop a voice-phishing scammer from secretly lifting the block online and pushing a loan through behind the victim's back. Keep in mind that if you urgently need a loan, getting the block lifted may take longer than you'd like.

Check your application history at the Korea Credit Information Services

Some people forget they set up the block, while others discover a family member applied for it on their behalf without telling them. Either way, you can log in at the Korea Credit Information Services (kcredit.or.kr) website, under the general credit information menu, to see exactly when and through which financial company you applied for the block, and whether it is currently active or lifted. If you're turned down for a new loan for no clear reason, this is the first screen to check.

If you've already been hit — reporting and checking go together

If a loan has already been issued or money has already left your account, the first step is to contact your bank's call center or the police (112) to request an account freeze. Identity theft rarely stops at a single loan, so it's worth checking whether a phone line has also been opened under your name while you're at it. On top of that, using the e-Privacy Clean Service to clear out sign-ups on unfamiliar sites closes off even more of the openings identity theft can exploit.

Putting the steps in order

①Check every account, card, and loan under your name at once through AccountInfo (payinfo.or.kr). ②You'll need a public certificate or a financial certificate to check. ③If nothing looks unfamiliar, apply for the Credit Transaction Safe-Blocking Service to shut off new loans entirely. ④You can apply through a bank app without visiting in person, but lifting the block requires a branch visit. ⑤You can check your application status anytime at the Korea Credit Information Services. ⑥If you've already been affected, report it to freeze the account and also clean up your phone line and site sign-up history to prevent it from happening again.
