How can I get back on NHIS (National Health Insurance Service) after being unenrolled?

To re-enroll in NHIS after being unenrolled, visit your local NHIS branch office with your passport, ARC, and proof of current residence in Korea such as a lease contract or utility bill. If you were unenrolled due to leaving the country for an extended period, you may need to show your entry stamp or immigration record proving you have returned.

There are a few things to be aware of. If you were unenrolled for not paying premiums, you will likely need to pay the outstanding balance before being re-enrolled. NHIS may also charge you retroactively from the date you became eligible again, which is typically the date you re-entered Korea or the date your new visa was issued. The process itself is usually straightforward and can be done in a single visit. Bring all your documents and the staff will handle the paperwork. Once re-enrolled, your coverage starts immediately. If you have trouble communicating, the NHIS customer service line at 1577-1000 has English support, and you can also ask them which branch office is closest to you.
