About Korean romanization

Romanization converts Korean text written in Hangul into the Latin alphabet so it can be read and typed by people and systems that don't use Hangul — needed for passports, international shipping addresses, academic citations, and official documents. This tool romanizes Korean names and road-name addresses following South Korea's Revised Romanization of Korean, the government-designated standard.

How the romanization is generated

Names and addresses are first decomposed into their individual Hangul components (initial, medial, and final consonant/vowel), then mapped to Latin letters according to the Revised Romanization rules — including sound-change rules like assimilation and liaison that adjust spelling based on how adjacent syllables actually sound when spoken together, not just a literal letter-by-letter substitution. Addresses are additionally parsed into their administrative parts (province/city, district, neighborhood, road, building number) and reordered into the building-number-first Western address format.

Frequently asked questions

Why doesn't this match the spelling on my existing passport?
Passport name romanization has historically had more individual flexibility, and older passports may use the previous McCune-Reischauer romanization system or a personally chosen spelling rather than the current Revised Romanization standard used by this tool — if you have an existing official document, that spelling generally takes precedence for consistency.
What are the sound-change rules mentioned, like assimilation and liaison?
Korean pronunciation shifts certain consonant sounds depending on what follows them — for example, 종로 is pronounced (and romanized) as "Jongno" rather than a literal "Jongro", because the 'ㄹ' sound assimilates to 'ㄴ' next to the preceding 'ㅇ' sound. The Revised Romanization standard requires reflecting these pronunciation shifts, not just transliterating each written syllable independently.
Does this handle compound Korean surnames?
Yes — the tool recognizes common two-syllable Korean surnames (like 남궁 or 황보) and keeps them together as the family name rather than misreading the first syllable as part of the given name.
