Raw JSON database for Vietnamese administrative addresses according to Resolution 202/2025/QH15.

This package contains only the raw database and is designed to be used as a dependency in other JavaScript/TypeScript libraries.

Installation

npm install vietnam-address-database

console.log(addressData[0].version); // "1.1"

Usage in other libraries

This package is designed to be required/imported in other libraries:

// In your address processing library
const vietnamAddressDB = require('vietnam-address-database');

// Parse the data structure
let provinces = [];
let wards = [];
let wardMappings = [];

vietnamAddressDB.forEach(item => {
  if (item.type === 'table') {
    if (item.name === 'provinces') {
      provinces = item.data;
    } else if (item.name === 'wards') {
      wards = item.data;
    } else if (item.name === 'ward_mappings') {
      wardMappings = item.data;
    }
  }
});

// Now you can implement your own functions
function getProvinces() {

  return provinces.find(p => p.province_code === code);
}

function getWardMappings() {
