A Shopify Plus checkout extension that brings Korea's standard address-entry pattern into Shopify. Rather than typing a street address, the shopper searches the official Korean government address database API, picks the matching result, and the postcode and address fields autopopulate. Built as a Checkout UI extension — so Plus only, since Shopify restricts that surface — with a settings panel for field customisation and drag-and-drop placement. A 2026 update added address autocomplete alongside Shopify's native autocompletion. $10/month, 14-day trial. Launched 13 August 2024.
