How can I check if I am enrolled in health insurance? Should I ask the company?

You don't have to ask the company for help. You can obtain the Health Insurance Qualification Certificate yourself through Government24 or the National Health Insurance Service. When a foreigner becomes a workplace subscriber, the employer must report to the National Health Insurance Service within 14 days from that date. If you have no records, first check whether the filing deadline has passed and has not yet been reflected in the inquiry. Having no records does not mean you are unenrolled, so ask the National Health Insurance Service at 1577-1000 about the date you obtained your qualification and the status of your report. This certificate allows you to check the period you have been enrolled in health insurance.
