Seal registration (인감 신고)
A person who wants a seal certificate must first register the seal with the certifying authority (증명청) that has jurisdiction over their address (or administratively managed address). A person with alien registration registers with the authority that has jurisdiction over their place of stay. The certifying authority is the mayor, county head or district head, and this seal work is delegated to the head of the eup, myeon or dong (or branch office), including for foreigners.
