China's Postal Code Format
China uses a "邮政编码" (postal code) system, which is a six-digit numeric format, like 999999, with no letters or separators. This format is similar to US ZIP codes in that both are numeric, but differs as China's postal codes have six digits compared to the five digits of standard US ZIP codes, and they do not feature the ZIP+4 extension. According to the GeoPostcodes world postal code database, China has 40,690 postal codes covering 59,683 regions and 1,008,545 towns.
Postal Code Format: 999999
- Six-digit numeric format (no letters)
- Some addresses use only the first four digits (default codes ending with 00)
- 40,690 postal codes covering 59,683 regions and 1,008,545 towns
Examples:
- 100000 - Beijing (Municipality)
- 200000 - Shanghai (Municipality)
- 510000 - Guangzhou, Guangdong
- 610000 - Chengdu, Sichuan
Structure of Postal Codes
- Format: 999999, numeric
- Hierarchical levels: 1–2 digits = main region; 3rd = postal region; 4th = county/city; last two = delivery area within that city.
- Key challenges: Postal codes don’t always fully align with administrative divisions; some regions use default 4-digit codes (ending “00”) instead of specific ones.
Management & Authority
- Primary postal authority: China Post.
- Update frequency: Uncertain, as administrative divisions change more frequently than postal codes.
Addressing Standards
- Common address format: Recipient → building → street → postal code → locality/county. Online it’s often one string from province down to street/number.
- Administrative divisions used: Provinces, autonomous regions, municipalities, prefecture-level cities, county-level divisions.
- Transliteration: Pinyin variations can affect search and validation.
Special Characteristics
- Some addresses use only the first four digits of the postal code, treated as "default postal codes" linked to "default regions" (ending with 00).
- Changes in administrative division names and status impact data stability.
- Geolocation accuracy is limited due to China's national policy on geospatial data security.
