Why Do You Need a Korean Address in English?

Whether you are shipping a package internationally, applying for a Korean visa, sending money overseas, or ordering from a Korean online store, you need your Korean address written in English. An incorrectly formatted address can lead to delivery delays, returned packages, or failed applications. JUSOME uses the official Korean Government Address API to provide accurate, internationally recognized English addresses instantly.

English-speaking users often struggle with the Korean address format, which reads from largest to smallest unit — the opposite of the Western convention. JUSOME automatically converts any Korean address into the correct international format, compatible with FedEx, DHL, EMS, Amazon, and major Korean online platforms like Coupang and Naver Shopping.

Understanding the Korean Address System

Korea uses two address systems. The road name address (도로명주소), officially adopted in 2014, is based on street names and building numbers — similar to Western addresses. For example: 1, Sejong-daero, Jung-gu, Seoul, Republic of Korea. This is now the standard for all government and business documents.

The older lot number address (지번주소) is based on land parcel numbers within administrative districts. For example: 1-1 Sejong-ro, Jongno-gu, Seoul. Many older records and buildings still use this system.

JUSOME supports both. Enter either address type and it will automatically provide the road name address, lot number address, English address, and postal code — all at once.

Official Format for Korean Addresses in English

Korean addresses in English follow the international small-to-large format: building number, street name, district (gu), city, country. For example, 서울 중구 세종대로 1 becomes 1, Sejong-daero, Jung-gu, Seoul, Republic of Korea.

For apartments, building (동) and unit (호) numbers use hyphens: 10동 1001호 becomes Apt. 10-1001. Korean postal codes are 5-digit numbers, written as Postal Code: 04524 or appended as (04524).

JUSOME follows all official international formatting standards, so the English addresses provided can be used directly on any international shipping form, visa application, or business document.

Using Korean Addresses for International Shipping

When shipping to Korea from abroad or sending packages internationally, an accurate English address is essential. Most international carriers require the address in English or Roman characters.

EMS (Korea Post) requires an accurate English address and postal code. FedEx and DHL recommend including a contact phone number alongside the address. For Amazon and eBay, simply copy the English address from JUSOME and paste it into the shipping fields.

JUSOME-converted addresses follow international standards and work with all major carriers. If a form requires fields split by street, city, and zip code, use the individual address components shown in the result.
