Korean Address to English — Convert & Validate (주소 영문)

Convert South Korean addresses to official English and validate them against the government's road-name address database (행정안전부 도로명주소, juso.go.kr). Paste addresses in Korean or English — road address, old lot-number (jibun) address, with apartment unit numbers or building names — and get:

• the official English road address (e.g. 152 Teheran-ro, Gangnam-gu, Seoul) and English jibun address;
• the 5-digit postal code, city/province, district and neighborhood in English;
• the unit romanized (101동 1203호 → 101-1203, 3층 → 3F, 지하1층 → B1F);
• a ready-to-print international mailing line: 101-1203, 152 Teheran-ro, Gangnam-gu, Seoul, 06236, Republic of Korea;
• whether the address exists, and alternatives when it is ambiguous.

No API key or Korean account needed. The official address API only issues keys to Korean registrants; this Actor gives you the same data in bulk, in English JSON.

Typical uses

• Cross-border e-commerce & shipping to Korea — validate customer addresses and print correct English labels.
• Forwarders and 3PL — normalize Korean addresses from orders, detect typos and non-existent addresses.
• CRM / data cleaning — convert Korean address columns to English with postal codes.
• AI agents — "What is this Korean address in English?", "Is this a valid address in Seoul?"
