A Korean 재직증명서 (Employment Certificate) is the workhorse document for almost any cross-border process that asks "what do you do for a living?" Skilled-worker visas, foreign mortgage applications, dependent-visa renewals, business-visitor letters, freelance tax filings abroad — they all want a recent 재직증명서, properly translated and often notarized.

This guide covers the 재직 vs 경력 distinction, what HR actually writes on the certificate, the job-title translation traps that get applications rejected, and how to translate cleanly in 2026.

재직증명서 vs 경력증명서 — the critical distinction

Two Korean certificates look almost identical but mean different things:

재직증명서 — "currently employed at" certificate. Issued by your current employer, valid for proving present employment status. Embassies and banks always want a 재직증명서 issued within the last 30–60 days.
경력증명서 — "career history" certificate. Lists past positions held at the issuing company. Valid even after you leave that employer. Useful for visa point systems and professional licensing that count years of experience.

A common error: applicants submit a 경력증명서 when the receiving party needs a 재직증명서. The two contain overlapping information but the issuing context is different. Ask in writing first.

What HR writes on a 재직증명서

A Korean Employment Certificate typically includes:

Employee's full name (Hangul + Hanja if used in older records) and RRN
Position / job title (직위, 직책)
Department (부서)
Date of hire (입사일자) and, if 경력, separation date (퇴직일자)
Salary information (선택 — often omitted unless requested)
Reason for issuance (발급 사유) — "for visa application", "for bank loan", etc.
Company name, registration number, address, phone
HR officer name and seal, plus company seal (법인인감)

The level of detail varies — some companies issue a one-line confirmation, others include the full employment package. Ask HR to include salary if your visa or mortgage requires it, since adding it later means a re-issued certificate.

Where it is required

재직증명서 translations appear in:

Skilled-worker visas (E-7 Korea, US H-1B, EU Blue Card, Australian 482) — proof of current employment
Mortgage applications abroad — income proof
Dependent-visa renewals — sponsor's employment proof
Freelance / contractor income proof for tax filings abroad
Professional licensing — years of experience for engineering, accounting, healthcare
Background checks for sensitive positions (banking, government contracting)

The receiving party's "valid issuance window" matters: most embassies require issuance within 30 days; banks within 60–90 days.

Translation pitfalls

Job title. Korean job titles use a hybrid of corporate hierarchy terms (사원, 대리, 과장, 차장, 부장, 이사) and functional titles (개발팀장, 마케팅 매니저). A literal translation like "차장 → Deputy Department Head" is technically correct but unfamiliar to foreign HR teams. The translator should use the equivalent foreign-system rank (Deputy Manager, Senior Manager, Director) while keeping the Korean title in parentheses for verification.

Department name. Korean departments mix English loanwords with Korean ("개발본부 마케팅팀"). The translation should preserve the hierarchy and use standard English department names — "R&D Division, Marketing Team" rather than literal "Development Headquarters Marketing Team".

Salary expression. Korean salaries are often expressed as 연봉 (annual) in KRW. The translation should keep KRW values as-is with a clear "KRW" label; do not auto-convert to USD/EUR — the receiving party will do its own conversion at its preferred FX rate.

Date format. Korean dates use YYYY.MM.DD. Many visa systems still process MM/DD/YYYY by default. Label clearly: "Date of hire (YYYY-MM-DD): 2018-03-15".

Company seal vs HR signature. Korean Employment Certificates carry two marks: the HR officer's signature/seal and the company seal (법인인감). Both must be visible in the translated layout. The company seal is the legally binding mark; missing it makes the certificate non-official.

Frequently asked questions

My company gave me an English 재직증명서 directly. Do I still need a translation? Often no, but check the receiving party's exact requirements — some only accept Korean-original + certified translation, not company-issued English versions.

Can the company seal be a digital signature instead of a physical stamp? Most embassies accept digital signatures from 공인전자서명 systems if the certificate shows the verification chain. Banks vary — ask first.

My job title doesn't have a clean English equivalent. How should it be translated? Use the closest functional equivalent (e.g., "Team Lead", "Senior Engineer") and keep the Korean title in parentheses. The receiving party can verify the original.

The salary on my 재직증명서 is in KRW. Should the translation convert it? No. Keep KRW values as-is. The receiving party will convert at its preferred FX rate.

A Korean Employment Certificate is one of the most reused documents in cross-border life — every new visa, every new mortgage, every new professional license needs a fresh one. Getting the job title and salary translated correctly once means you only have to update the dates each time.
