South Korea address format notes
Romanized Korean road-name addresses place the building number with the road name, followed by district, city or province, postal code, and country.
Postal code
Current postal codes use five digits; generation is format-only rather than a road-address database lookup.
South Korea uses five-digit postal codes. These samples do not claim road-level compatibility.
Phone format
Phone values are non-contact format examples.
Common mistakes
- Using the retired six-digit postal-code assumption.
- Forcing Korean data into a US city/state hierarchy.
- Treating romanized output as deliverability verification.
