Vietnam Address Assistant

Vietnam replaced 63 provinces with 34 provinces and removed the district level on 1 July 2025. Customers still type old districts and wards at checkout, forcing merchants to rewrite addresses manually. This app reads the checkout address, matches it to the new province and ward, then shows the result on the Thank you page. Buyers confirm it or pick another ward in one tap. Only their confirmation saves the address to the order. The shipping address typed at checkout is never edited, and no buyer data is stored. Features full 2025 administrative data with all 34 provinces and every new ward. Saves confirmed addresses to order attributes and metafields. Works on standard Shopify checkout without needing Shopify Plus.
