South Korea's Postal Code Format
South Korea uses a “우편번호” (postal code) system, which is a five-digit numeric format like 99999, with no letters or separators. This means it uses only numbers, and is the same as the US ZIP codes. According to the GeoPostcodes world postal code database, South Korea has 34,395 postal codes covering 269 regions and 5,050 towns.
우편번호 Format: 99999
- 5-digit numeric (introduced in 2015; previous system was 6-digit)
- 34,395 postcodes covering 269 regions and 5,050 towns
Example:
- 05581 - Seoul
Structure of Postal Codes
- Format: 99999, numeric
- Hierarchical levels: First 3 digits = broad administrative areas (provinces, metropolitan cities); last 2 digits = sequential / routing-based.
- Key challenges: Not perfectly aligned with administrative boundaries (mix of administrative and routing logic). Designed primarily for street-based addressing rather than locality-level aggregation.
Management & Authority
- Primary postal authority: Korea Post (www.koreapost.go.kr) and the Ministry of the Interior and Safety.
Addressing Standards
- Common address format: [Street Number] [Street Name], [Dependent Locality], [Post Town in Capitals] [Postcode]
- Administrative divisions used: 17 Sejong-daero, Jung-gu, SEOUL 04524
