Korea's 4 Major Social Insurance Enrollment Verification: Complete Guide for Foreign Workers

What Is 4 Major Social Insurance Enrollment Verification?

Korea's 4 major social insurances (4대보험) refer collectively to the National Pension (국민연금), Health Insurance (건강보험), Employment Insurance (고용보험), and Industrial Accident Compensation Insurance (산재보험). All workers are legally required to be enrolled, and employers must file an enrollment (acquisition) report with each relevant agency immediately upon hiring a worker. "4 Major Social Insurance Enrollment Verification (4대보험 가입확인)" is the process of officially confirming — through formal documents — whether you are currently or were previously enrolled in these insurances.

How to Check Your Enrollment Online

1. National Health Insurance Service Website

Visit the National Health Insurance Service website (nhis.or.kr) and log in with a joint certificate (공동인증서) to obtain the '4 Major Social Insurance Subscriber Enrollment History Certificate (4대사회보험 가입자 가입내역 확인서)' free of charge. Your enrollment history for all four insurances — National Pension, Health Insurance, Employment Insurance, and Industrial Accident Insurance — is printed on a single document.

2. Government24

The same certificate can be issued through the Government24 portal (gov.kr). This service has been available since the former Minwon24 era. Log in with a joint certificate or a simple authentication method (e.g., Kakao, Naver) and search for "4대보험."

3. Employment Insurance Website

The Employment Insurance website (ei.go.kr) allows you to check your Employment Insurance insured status history separately. You can confirm your acquisition date, loss date, and reason for loss — useful for verifying eligibility for unemployment benefits (실업급여) or reviewing your job-change history.

Key Uses of the Enrollment Verification Certificate

① Proving Employment History (경력 증명)
The certificate is useful when you need to prove your period of employment at a previous workplace during a job change. This is especially important when a former employer has closed down and cannot issue an employment certificate. A Ministry of Employment and Labor administrative interpretation (고용노동부 행정해석, 2009.5.27.) states that in such cases, employment history may be recognized through objective documents including Employment Insurance system records, a withholding tax receipt (원천징수영수증), an income amount confirmation (소득금액확인서), and a 4 Major Social Insurance Enrollment Verification Certificate.

② Checking Eligibility for Unemployment Benefits (실업급여 수급 요건 확인)
To receive job-seeker benefits (구직급여), you must have accumulated at least 180 insured days within the 18 months prior to your separation date (Article 40 of the Employment Insurance Act, 고용보험법 제40조). You can use the enrollment certificate to calculate your insured period in advance.

③ Checking National Pension Enrollment History
You can confirm your enrollment period, which forms the basis for calculating your estimated National Pension benefit amount. If there are any gaps in your enrollment, note that since October 20, 2026, a foreign subscriber may apply for retroactive contributions (추납) only if their home country's pension law gives Korean nationals a comparable option (Article 126(6) of the National Pension Act / 국민연금법 제126조 제6항); from April 21, 2027, certain foreigners designated by Presidential Decree (based on visa status, length of residence and contribution period) will also be eligible. Check with the National Pension Service (국민연금공단).

2026 Four Major Social Insurance Rates at a Glance

For 2026, the upper limit of the standard monthly income (기준소득월액) for National Pension is KRW 6,590,000 and the lower limit is KRW 410,000 (applicable July 2026 – June 2027).

Note: These are statutory rates. Your actual deductions may differ if your employment contract specifies different conditions, though statutory minimums always apply.

What to Do If Your Employer Fails to Enroll You

If your employer has failed to file an enrollment report for the 4 major social insurances, you may report your acquisition of insured status under Employment Insurance yourself (Article 15(3) of the Employment Insurance Act, 고용보험법 제15조 제3항), and for the National Pension and Health Insurance you may request confirmation of your status (Article 14(4) of the National Pension Act, 국민연금법 제14조 제4항; Article 11(2) of the National Health Insurance Act, 국민건강보험법 제11조 제2항). Article 21 of the National Pension Act (국민연금법 제21조), Article 8(2) of the National Health Insurance Act (국민건강보험법 제8조 제2항), and Article 15 of the Employment Insurance Act (고용보험법 제15조) all stipulate the employer's reporting obligation. Violations may result in retroactive collection of insurance premiums. For the National Pension and Employment Insurance, failure to report is also subject to an administrative fine (Article 131(1)1 of the National Pension Act, 국민연금법 제131조 제1항 제1호; Article 118(1)1 of the Employment Insurance Act, 고용보험법 제118조 제1항 제1호).
