Four Major Social Insurance Enrollment Certificate: How to Get It and Where to Use It (2026)

What Is the Four Major Social Insurance Enrollment Certificate?

The four major social insurance enrollment certificate (4대보험 가입확인서) is an official document proving that you are currently enrolled in Korea's four social insurances: National Pension (국민연금), Health Insurance (건강보험), Employment Insurance (고용보험), and Industrial Accident Compensation Insurance (산재보험). It is required in a wide range of situations — employment, job changes, loans, visa applications, housing subscription (청약), and more — so knowing how to obtain it in advance will save you considerable time.

Note for foreign workers: Your employment contract may specify terms that differ from the statutory minimums, but enrollment in the four major insurances is a legal obligation, not a contractual option.

This article does not cite specific court rulings and is written primarily with reference to the relevant statutory provisions.

Legal Basis for Mandatory Enrollment

Enrollment in the four major social insurances is a legal obligation, not a choice.

• National Pension: Under Article 8 of the National Pension Act (국민연금법 제8조), workers aged 18 or older and under 60 are mandatory subscribers.
• Health Insurance: Under Article 6 of the National Health Insurance Act (국민건강보험법 제6조), all workers at workplaces are automatically enrolled as workplace subscribers (직장가입자).
• Employment Insurance: Under Article 8 of the Employment Insurance Act (고용보험법 제8조), the insurance applies to any business that employs workers, and the employer bears the obligation to report the acquisition of insured status.
• Industrial Accident Compensation Insurance: Under Article 6 of the Industrial Accident Compensation Insurance Act (산업재해보상보험법 제6조), the insurance applies automatically to all businesses that employ workers.

Workers employed for fewer than 15 hours per week (ultra-short-hour workers, 초단시간 근로자) may have limited coverage under National Pension and Health Insurance, but Employment Insurance and Industrial Accident Insurance apply to them in principle.
