Until when do I need to claim the return expense insurance?

The period during which you can file a claim with the insurer is three years from the date you start receiving the insurance payout. If three years have passed, check if the transfer has been transferred to the Human Resources Development Service of Korea and apply for dormancy insurance. For insurance company claims, contact 1600-0266; for corporation applications, contact the Korea Industrial Human Resources Corporation at 1644-8000. This is different from the Departure Maturity Insurance or the Lump-Sum Return of the National Pension.
