How to Update Your Address on Korea’s Health Insurance Card (NHIS Official Guide)

Moving to a new home in Korea is exciting — but it comes with a critical admin task that many foreigners overlook: updating your address with the National Health Insurance Service (NHIS, 국민건강보험공단). Miss this step and your premium bills, insurance correspondence, and the physical health insurance card itself may never reach you.

This guide covers exactly how to update your NHIS address record after moving, which documents you need, and where to go — based entirely on official NHIS sources.

Key Takeaways

Key Takeaways

• Notify NHIS of your new address within 14 days of moving to avoid missed premium notices.
• Visit the nearest NHIS Center for Foreign Residents — specialized centers exist in Seoul, Ansan, Suwon, Incheon, and Uijeongbu.
• Bring your Alien Registration Card (ARC) as your primary identification document.
• Update your ARC address at the local immigration office before visiting NHIS for a smoother process.
• Multilingual support (English, Chinese, Vietnamese) is available at 033-811-2000.

Why Your NHIS Address Record Matters

Your registered address in the NHIS system is the delivery destination for:

• Monthly premium invoices — non-delivery can lead to missed payments and potential coverage penalties
• Your physical health insurance card (건강보험증) — mailed to your address upon initial enrollment or re-issuance
• Official policy notices and eligibility certificates
• Health checkup notices and results

According to the Seoul Metropolitan Government’s official insurance guidance, if you move and fail to report your new address, “detailed address information must be accurately reported to prevent disadvantages due to failure to deliver mailed materials.” (Source: Seoul Metropolitan Government — Insurance)

Who Needs to Update Their NHIS Address?

You must update your NHIS address record if you:

• Move to a new apartment, house, or room within Korea
• Relocate from one city to another (e.g., Seoul to Busan)
• Change university dormitories
• Move from a goshiwon (고시원) to a regular apartment
• Change your registered household address for visa/ARC purposes

This applies to all NHIS subscribers — whether you’re on an employer-sponsored plan (직장가입자) or a self-employed/local plan (지역가입자).

Step 1: Update Your Alien Registration Card Address First

Before visiting NHIS, update the address on your Alien Registration Card (ARC) at your local immigration office. Your NHIS subscriber record is linked to your ARC registration, so keeping them in sync avoids discrepancies during verification.

To update your ARC address:

1. Visit the immigration office (출입국사무소) with jurisdiction over your new address
2. Submit a Change of Place of Residence Report (체류지변경신고)
3. Present your ARC, passport, and proof of new address (e.g., lease agreement)
4. Report within 14 days of moving (required by immigration law)

For guidance on immigration procedures, contact the Immigration Information Center at 1345 (available in English, Chinese, Vietnamese, and more). Official portal: Hi Korea (hikorea.go.kr)

Step 2: Notify NHIS of Your New Address

After updating your ARC, notify NHIS directly. The primary method for foreigners is a visit to the NHIS Center for Foreign Residents that covers your new residential area.

According to the official NHIS English website, foreigners who wish to report changes such as their place of residence, passport number, or visa must visit the designated NHIS Center for Foreign Residents with jurisdiction over their residential address. (Source: NHIS — Guidance for Foreigners)

• Proof of new address — lease agreement (전세/월세 계약서), utility bill, or official move-in confirmation

For registering foreign dependents (e.g., a spouse or child whose documents are from abroad), additional documents are required:

1. Family relations certificate or marriage certificate
2. Certification by the Foreign Ministry (overseas) or an Apostille
3. A Korean translation notarized by a notary public, dated within 9 months

What Happens If You Don’t Update Within 14 Days?

The 14-day notification window is not merely advisory. If you miss it:

• Premium invoices go undelivered — you may accumulate unpaid balances without realizing it
• Late payment surcharges may apply if bills are not received and paid on time
• Health insurance card or official documents sent to your old address cannot be forwarded
• Your employer or NHIS may be unable to contact you regarding coverage changes

This 14-day requirement is stated in official guidance from the Seoul Metropolitan Government’s living resources for foreigners. (Source: Seoul Metropolitan Government — Insurance)

Frequently Asked Questions

Can I update my NHIS address online without visiting an office?

NHIS does provide online services through the NHIS website (nhis.or.kr), but the official guidance specifically directs foreigners to visit an NHIS Center for Foreign Residents in person for address and personal information changes. Phone consultation is available at 033-811-2000 to clarify what can be handled remotely.

Does updating my ARC address automatically update my NHIS record?

Not necessarily. While your ARC and NHIS records are linked, NHIS explicitly instructs foreigners to separately report address changes to their dedicated Foreign Residents Centers. Updating only your ARC without notifying NHIS may leave your insurance billing address unchanged.

I moved outside Seoul — which NHIS center do I use?

NHIS Centers for Foreign Residents in the Seoul–Gyeonggi–Incheon area are located in Guro-gu (Seoul), Ansan, Suwon, Bupyeong (Incheon), and Uijeongbu. For other regions, contact the main NHIS call center at 1577-1000 or the English line at 033-811-2000 to locate the nearest branch.

What languages does NHIS support for foreigners?

NHIS provides consultation in English, Chinese (Mandarin), Uzbek, and Vietnamese through the dedicated foreign language line at 033-811-2000. The main 1577-1000 line also connects to foreign language support by pressing extension 6. Source: NHIS official Contact Us page (nhis.or.kr/english/wbheaa02000m01.do).

Can I request a reissue of my health insurance card if it was sent to the wrong address?

Yes. After updating your address with NHIS, you can request a new card to be sent to your correct address. Contact the NHIS call center at 1577-1000 or visit your nearest NHIS branch or Foreign Residents Center.

Conclusion

Updating your NHIS address after moving in Korea is a straightforward process — but it requires action on your part. The 14-day window is tight, so make it part of your move-in checklist: update your ARC first, then visit the NHIS Center for Foreign Residents nearest to you with your ARC in hand.

For any questions, the NHIS English-language line at 033-811-2000 is your fastest resource. All center addresses and contact numbers in this guide are sourced directly from the official NHIS website.
