KorAddress: Korean Postcode

Korean shoppers expect a postcode search (우편번호 검색), not free-text address fields. Shopify's own autocomplete does not cover Korea, so KR customers type everything by hand and drop off on mobile. KorAddress puts the Daum/Kakao postcode search on your cart page and cart drawer. Customers pick an address, add a detail line (상세주소), and reach Shopify's native checkout with shipping prefilled. If anything fails, checkout opens as usual — the widget never blocks a sale.
