Vietnam Address Assistant

Vietnam switched to a two-tier administrative system on 1 July 2025 with 34 provinces and 3,321 wards—districts are gone. But buyers still type old district names at checkout, creating address problems for shipping. This app adds a confirmation block to your Thank you page. It pre-fills the new province, ward and street from the address your buyer already entered. The buyer can review everything, fix any mistakes, and confirm. Once confirmed, the app writes province, ward, street and delivery notes to order attributes—your original Shopify shipping address stays untouched. Coverage includes all 34 provinces and 3,321 wards in both Vietnamese and English, so every order carries accurate location data for fulfillment.
