Korean Passport Name Romanization Guide (Korean Name to English Spelling)

Last updated: 2026-06-25

Why a passport English name deserves care

A passport English name is the reference for all identity information used abroad — airline tickets, visas, overseas remittances, study and work documents. If a single letter differs between your ticket and passport, you may be denied boarding, and a mismatch between a visa and a passport can delay issuance. That is why it is most important to set the English name correctly the first time. On top of that, a registered passport English name is, in principle, hard to change, so it is better to understand the spelling rules and decide deliberately rather than on a whim.

Basic principle: National Institute of Korean Language romanization

When transcribing a Korean name into Roman letters, Korea uses the Romanization of Korean announced by the National Institute of Korean Language (revised in 2000) as the standard. This scheme aims to render the actual pronunciation of Korean as closely as possible in the English alphabet. The key points are as follows.

• Vowels — ㅏ a, ㅓ eo, ㅗ o, ㅜ u, ㅡ eu, ㅣ i. Writing "ㅓ" as "eo" and "ㅡ" as "eu" is the part most easily confused with English-style spelling.
• Consonants — the plain consonants ㄱ, ㄷ, ㅂ are g, d, b before a vowel and k, t, p as a final or before a consonant. ㅈ j, ㅊ ch, ㅋ k, ㅌ t, ㅍ p, ㅎ h.
• ㄹ — r before a vowel, l before a consonant or at the end of a word. ㄹㄹ is written ll.

Our Korean name to English converter applies these rules approximately and shows the surname and given name separately. For example, "김민수" becomes Kim Minsu and "강하늘" becomes Kang Haneul.

Surnames prefer the conventional spelling

Unlike given names, surnames overwhelmingly use conventional spellings that became fixed before the romanization scheme. By the romanization rules, "김" would be Gim, "이" would be I, and "박" would be Bak, but in practice almost everyone uses Kim, Lee, and Park. The Ministry of Foreign Affairs also accepts these common spellings.

Just as "정" splits into Jeong, Jung, or Chung and "이" into Lee, Yi, or Rhee, the same surname can have several spellings. There is no single correct answer; the most important thing is to follow the spelling your family already uses.

Joined or hyphenated given name?

A two-syllable given name can be spelled two ways. First, joining the syllables (e.g. 민수 → Minsu), and second, putting a hyphen between syllables (e.g. 민수 → Min-su). Both are allowed, and the Ministry of Foreign Affairs treats the hyphen as optional.

• Joined (Minsu) — the most common and concise. However, syllable boundaries can become ambiguous, as in "Seungah".
• Hyphenated (Min-su) — clearer syllable separation that is easier for non-Koreans to read. Writing "승아" as Seung-ah reduces pronunciation confusion.

Whichever you choose, it is best to stay consistent with existing documents (the English name on your resident registration, school records, family passports). Our converter shows both spellings, so compare them and choose.

Should you apply sound changes (consonant assimilation)?

Korean undergoes consonant assimilation, where pronunciation changes as syllables connect. For example "신라" sounds like [silla] and is written Silla, and "독립" sounds like [dongnip] and is written Dongnip. The romanization scheme, in principle, reflects these pronunciation changes.

Personal names, however, are a little different. Passport names tend to be spelled syllable by syllable, so many people prefer a spelling that does not apply sound changes. For example, whether to write the name "한라" as Halla by pronunciation or Hanra by syllable is your choice. Our converter shows a result that approximately reflects sound changes, so use it as a reference but adjust it yourself if you need a syllable-by-syllable spelling.

Family consistency matters most

The most common problem with passport English names is that family members spell the surname differently. If a father is Lee while a child is Yi, you may be asked for extra documents to prove the family relationship abroad. So the principle is to check the surname spelling on an earlier-issued family passport and match it exactly. Be sure to align a child's first passport with the parents' surname spelling.

Spelling changes are limited

A passport English name is, in principle, hard to change once registered. However, it may be changed in limited cases with a valid reason such as the following.

• A clear spelling typo (e.g. entering Minsu as Minssu by mistake)
• A spelling that clearly violates the romanization rules and needs correction
• Aligning the surname spelling with family members
• Resolving a mismatch with another long-used spelling (proof required)

Whether a change is possible and what documents are required vary case by case, so always confirm with the Ministry of Foreign Affairs passport guide or your passport issuing office.

Passport English name checklist

• Did you first check the surname English spelling on family (parents'/siblings') passports?
• Did you decide whether to use the joined or hyphenated style for the given name?
• Did you decide whether to apply sound changes (e.g. Silla vs. Sinra)?
• Does it match your tickets, visa, and existing documents?
• Did you confirm the final spelling at the Ministry of Foreign Affairs passport guide?

Summary

• A passport English name is recommended to follow the National Institute of Korean Language romanization, but it is not mandatory.
• Surnames prefer conventional spellings like Kim, Lee, Park, and should be consistent across the family.
• Given names can be joined (Minsu) or hyphenated (Min-su); consistency matters.
• A spelling is hard to change once set, so decide carefully before applying and confirm finally with the Ministry of Foreign Affairs.
