e-Privacy Clean Service -- Find Every Site You've Signed Up For and Withdraw From All of Them at Once

You Don't Have to Hunt Down Every Site One by One

How the Lookup Works -- Based on Identity Verification Records

The service works by consolidating your identity verification history (resident registration number, i-PIN, mobile phone verification) used whenever you signed up, confirmed your real name, or verified your age online. After authenticating at eprivacy.go.kr with a certificate, simple authentication (KakaoTalk, Naver, PASS, etc.), or i-PIN, the 'Membership Status Lookup' menu shows every site where an identity verification record exists.

How Far Back, and How Complete, the Lookup Goes

Records verified by resident registration number or i-PIN are searchable for up to 5 years, while mobile phone verification records only go back up to 1 year. If you signed up more than 5 years ago and never re-verified your identity there since, that site may not show up on the list. The service also only covers businesses linked to identity verification agencies, so small communities, overseas services, and sites that only require email or social login won't appear. Those sites can't be handled through bulk withdrawal -- you'll need to log in directly to cancel, or contact the site operator to request deletion.

How the Bulk Withdrawal Request Works

Check the boxes next to the sites you want to leave, and Clean Service forwards a withdrawal request to each business on your behalf. You can track the status under 'Application History Lookup,' and it typically takes about 3 to 7 business days to complete. Processing methods vary by business, so some don't reflect the change immediately -- it's safer to check back a few days after submitting. If you see several sites on the list you don't remember joining, it's worth wondering whether your sign-up information ended up somewhere else without your knowledge. If you've ever received a notice about a data breach penalty case, it's worth cross-checking that against this list as well.

When a Withdrawal Request Doesn't Go Through

Sometimes a business ignores or refuses a withdrawal request even after you've submitted one. When that happens, don't just keep refreshing the Clean Service screen -- you can file a report with the Korea Internet & Security Agency (KISA) Personal Information Infringement Report Center (privacy.kisa.or.kr, or call 118, no area code needed). Once a report is filed, it's reviewed for legal violations and administrative guidance is issued requiring correction; if the business still doesn't comply, the case escalates to a formal administrative investigation, with results reported to the Personal Information Protection Commission. When filing, gather evidence such as the date you requested withdrawal and screenshots showing the refusal -- it speeds up processing.

A Different Process From Your Access/Deletion Request Rights

Requesting access, deletion, or processing suspension is an individual right you exercise directly against a specific business you already know about. Clean Service, by contrast, is for when you don't even know where you've signed up -- it finds your registration history itself and files the withdrawal on your behalf. The purposes are different. If you already know which site holds your data and want to make sure it's actually deleted, use the access/deletion request alongside Clean Service.

Don't Confuse This With an Identity-Theft Check

Clean Service organizes sites you actually signed up for yourself, while checking whether a phone line was secretly opened under your name is about finding telecom lines opened without your knowledge. Both protect your personal information, but they cover different problems -- use M-safer if you suspect identity theft, and Clean Service if you want to clean up accounts you'd simply forgotten about.

Steps in Order

First, go to eprivacy.go.kr and verify your identity with a certificate or simple authentication. Second, check the list of sites with identity verification records under 'Membership Status Lookup.' Third, check the boxes for the sites you want to leave and submit a bulk withdrawal request. Fourth, check the processing status under 'Application History Lookup' after 3 to 7 business days. Fifth, for older accounts or small sites that don't appear on the list, log in directly to withdraw or contact the operator to request deletion. Keep in mind from the start that accounts past the identity-verification lookup window (5 years for resident registration number/i-PIN, 1 year for mobile phone verification) can't be found through this service.
