How to Register a Retired Parent as a Health Insurance Dependent (Code 07)

When registering a parent who has recently left their job as a National Health Insurance dependent in South Korea, the correct acquisition code to use is ’07’, which designates a transition from regional subscriber status, according to the National Health Insurance Service.

Navigating the dependent registration process requires strict adherence to statutory deadlines and documentation rules set by South Korean health authorities. According to the National Health Insurance Service, the primary subscriber—the working child—must initiate the application directly rather than the dependent parent. Applications submitted within 90 days of the dependent’s loss of workplace subscriber status, which occurs the day after resignation, allow the dependent’s qualification to be retroactively applied. Filings completed after this 90-day window take effect only from the actual date of submission.

Required Documentation and Filing Procedures

Applicants must supply a detailed certificate of family relations issued within the preceding three months, according to official agency guidelines. This document must display all resident registration numbers in full. Submissions can be completed online through the Four Major Public Insurance Information Linkage Center portal or the official National Health Insurance Service website. After logging in, applicants select the dependent qualification acquisition menu, input the parent’s personal details, relationship status, acquisition date, and the specific acquisition code ’07’, before uploading the required PDF or image files of the supporting certificates.

Verifying Qualification Loss Dates

Exact dates for qualification loss can be verified prior to filing by accessing the qualification inquiry menu on the National Health Insurance Service website or through the official mobile application, according to health authorities. Ensuring the precise date prevents processing delays caused by mismatched timelines during the review of the electronic application.
