Passport Name Romanizer
Turn a Korean name into its passport spelling, following the official romanization rules.
About this tool
When you apply for a Korean passport you have to decide how your name is spelled in the Latin alphabet. This tool applies the official Revised Romanization rules to produce a standard spelling and shows the alternatives that are also accepted. Type your surname and given name together and it separates them for you.
Surnames are the tricky part. The rules would give one spelling, but passports accept the conventional forms that have been in use for decades — Lee rather than I, Kim rather than Gim, Park rather than Bak. So the surname options are listed roughly in order of how commonly they are used and you pick one. Two-syllable surnames such as Namgung and Seonwoo are detected automatically; if yours is not, set the surname length yourself.
Given names are written as one word by default, and a hyphen between syllables is also permitted. Two things are worth knowing. If you already hold a passport, the spelling on it is the one you should keep — changing a romanized name later is difficult. And families are best keeping a single spelling of the shared surname, because differing spellings make proving a family relationship abroad more troublesome. The conversion runs in your browser and your name is never sent to a server.
