I am leaving Korea and want to make sure I do not miss any important mail after departure?

Korea Post does not offer international mail forwarding in the traditional sense, so you need to plan ahead. The most reliable approach is to update your address with every important sender before you leave, including your bank, immigration, NHIS, NPS, your employer, and any subscription services.

For mail that arrives after your departure, you have a few options. You can ask a friend in Korea to receive and scan or forward important documents. Some expats use paid mail forwarding services like ePostBox or similar virtual address providers, which receive your mail, scan it, and forward physical items abroad for a fee. The cost is usually around 30 to 50 thousand won per month plus shipping.

For tax documents and pension refund notices specifically, register an overseas address with the National Tax Service and NPS before you leave. They will send notices to your foreign address directly. Also set up online accounts for your Korean bank if you have not already, since some require periodic confirmation that you can do remotely with a registered overseas address.
