Additionally, outbound services have resumed to all countries for which it is currently possible.

International air traffic is limited to charter and cargo flights only, with operations mainly confined to a few flights from Ulaanbaatar to Seoul. Mongol Post is accepting all types of mail to a reduced number of destinations to include the United States of America. It is also able to accept and deliver all types of inbound mail received via Seoul, but there may be some delays due to sanitization processes at the exchange office.
