Want to advertise your business in Naver Search AD or Korean shopping websites? You will need a digital marketing registration, or in Korean 통신판매업 신고증. A digital marketing registration is also known as mail-order business, telemarketing or online marketing registration.
With these two documents, you go to the district office (구청) of where your office is located. You may want to make sure the name of the business registration matches the one on the digital marketing registration (for example both in Korean or in English). The whole process will take around 3 working days.
