Chinese Province Codes: Complete ISO 3166-2:CN Reference (2026)

China has 34 province-level administrative divisions, each with an ISO 3166-2:CN code. This reference covers all provinces, municipalities, autonomous regions, and special administrative regions.

Overview

Municipalities (4)

Municipalities are province-level cities under direct central government administration.

Provinces (23)

Note on Taiwan (CN-71): ISO 3166-2 lists Taiwan as a province of China under code CN-71. However, Taiwan also has its own ISO 3166-1 entry as a separate territory with alpha-2 code TW (alpha-3 TWN, numeric 158). The @koshmoney/countries package includes both entries. Use TW when you need to reference Taiwan as a distinct entity.

Autonomous Regions (5)

Autonomous regions have larger populations of ethnic minorities and enjoy certain legislative rights.

Special Administrative Regions (2)

SARs operate under the “one country, two systems” principle with their own legal and economic systems.

Note: Hong Kong and Macau each have their own ISO 3166-1 alpha-2 codes (HK and MO). When building address forms or shipping integrations, use HK and MO as separate country entries rather than CN-91/CN-92.

Code Examples

Look Up All Chinese Subdivisions

import { subdivision } from '@koshmoney/countries';
 
// Get all 34 subdivisions
const cnSubs = subdivision.getByCountry('CN');
console.log(cnSubs.length); // 34

Look Up a Specific Province

import { subdivision } from '@koshmoney/countries';
 
subdivision.get('CN-44');
// { code: 'CN-44', name: 'Guangdong', type: 'Province' }
 
subdivision.get('CN-11');
// { code: 'CN-11', name: 'Beijing', type: 'Municipality' }
 
subdivision.get('CN-91');
// { code: 'CN-91', name: 'Hong Kong', type: 'Special administrative region' }

Validate a Province Code

import { subdivision } from '@koshmoney/countries';
 
subdivision.isValidCode('CN-44');    // true (Guangdong)
subdivision.isValidRegion('CN', '44'); // true
subdivision.isValidCode('CN-99');    // false

Tree-Shaking: Import Only China Data

// Import only Chinese subdivisions for smaller bundles
import { subdivisions } from '@koshmoney/countries/subdivision/CN';
 
Object.keys(subdivisions);
// ['CN-11', 'CN-12', 'CN-13', ..., 'CN-92']

Use Cases

E-Commerce Shipping

Chinese provinces have different shipping zones and delivery times. Use subdivision codes to determine shipping rates:

import { subdivision } from '@koshmoney/countries';
 
function getShippingZone(provinceCode: string): string {
  const sub = subdivision.get(provinceCode);
  if (\!sub) return 'unknown';
 
  // SARs ship differently
  if (sub.type === 'Special administrative region') return 'sar';
  // Municipalities tend to have faster delivery
  if (sub.type === 'Municipality') return 'tier-1';
  return 'standard';
}

Address Validation

Validate that a province code belongs to China before processing:

import { subdivision } from '@koshmoney/countries';
 
function validateChineseAddress(provinceCode: string): boolean {
  return subdivision.isValidCode(provinceCode)
    && provinceCode.startsWith('CN-');
}

Numbering System

China’s subdivision codes follow a geographic numbering pattern:
