Regularly updated dataset of China's administrative divisions with ID-card address parsing. Distributed via Composer and versioned for use in forms, validation, and address-related scenarios.

This project has been parsed by Zread. View project overview

Features

• 📦 Nationwide administrative division data, synced regularly from public sources like the National Bureau of Statistics
• 🆔 ID-card parsing: address lookup, gender, date of birth, and checksum validation
• 📅 Historical data and change records — trace revoked, merged, or renamed regions
• 🔗 Built-in cascader data conversion, ready for frontend province-city-district linkage components
• 🏷 City tier classification (level_1 / level_2 / level_3)
• 🚀 Composer install, zero dependencies

Requirements

• PHP >= 7.4

Installation

composer require hejunjie/china-division

Included Data Files

File	Description
data.json	Current valid administrative division data
history.json	Historical region data (revoked, merged, or renamed regions)
diff.json	Administrative division change records (region code mappings)

You can also work with the JSON files directly without the Division helper class.

Usage

Retrieving Data

<?php
use Hejunjie\ChinaDivision\Division;

// Current division data
$data = Division::getData();

// Historical division data
$history = Division::getHistory();

// Change records
$diff = Division::getDiff();

ID-card Parsing

<?php
use Hejunjie\ChinaDivision\Division;

// Get province, city, and district from an ID-card number
$info = Division::getAddressInfo('11010119960124993X');
// ['province' => '北京市', 'city' => '市辖区', 'area' => '东城区']

// Get gender
$sex = Division::getGenderFromIdCard('11010119960124993X'); // '男'

// Get date of birth
$birthday = Division::getBirthdayFromIdCard('11010119960124993X');
// ['year' => '1996', 'month' => '01', 'day' => '24']

// Validate an ID-card number
$isValid = Division::isValidIdCard('11010119960124993X'); // true

Cascader Data & City Tiers

<?php
use Hejunjie\ChinaDivision\Division;

// Convert to cascader format (for frontend province-city-district linkage components)
$cascaderData = Division::convertToCascaderData();

// Get city tier data (level_1 / level_2 / level_3)
$levels = Division::getCityLevels();

Note

The methods above provide basic usability. For performance-critical scenarios, consider caching the data in Redis and implementing your own query logic.
