How to Check if a Korean Company is ”Safe” Before You Work

Did you know that in South Korea, foreign workers are disproportionately affected by wage theft? Recent data shows that while foreigners make up just 3.2% of the workforce, they account for 8.5% of all unpaid wage victims. That means as an expat, you are almost three times more likely to have your salary unpaid compared to a local Korean worker.

To make sure you aren't the next person working for free, you must verify that a company is "safe" before you ever sign an employment contract. This means doing your own background check to confirm they are a legally operating business with absolutely no history of labor violations or financial fraud.

Here are the two absolute legal checks you must perform on every Korean employer before you accept a job offer.

1. Verify Their Business Registration Number

Every legitimate company in South Korea has a 10-digit National Business Registration Number (사업자등록번호). By law, companies are required to display this number, usually at the very bottom footer of their official website. If a company does not publicly list this number, consider it your first major red flag.

Once you find the 10-digit number, you need to verify it through the Korean government.

1. Navigate to the National Tax Service (NTS) Hometax website.
2. Go to the business status inquiry page by clicking 증명-등록-신청 > 사업자등록 신청-정정-휴폐업 > 사업자상태 조회(사업자등록번호).
3. Enter the 10-digit business number and hit search

How to Read the Results:

• Clean & Legitimate: If the company is actively operating and paying taxes, the system will return the message: "부가가치세 일반과세자입니다" (General Value-Added Taxpayer).
• Danger Zone: If the company has shut down, gone bankrupt, or was caught for tax fraud, it will say "폐업자" (Closed Business) along with the date and reason. Never sign a contract with a closed entity.
• Fake Company: If you get an error saying "국세청에 등록되지 않은 사업자등록번호입니다" (Unregistered Business Number), the company is using a fake ID.

2. Check Their Labor Fraud History

Just because a company pays its taxes does not mean it pays its employees. With unpaid wages in Korea reaching record highs, surpassing 1.2 trillion won in just the first half of 2024, you must check if the employer has a history of wage theft.

To do this, you need to use the Ministry of Employment and Labor (MOEL) database. The Korean government publicly names and shames delinquent employers who have a legal record of malicious labor violations.

1. Navigate to the Ministry of Employment and Labor official website.
2. Look for the public disclosure list of delinquent employers (체불사업주 명단공개).
3. Search for the company’s official Korean name or the CEO's name.

If the company appears on this list, it means they have been legally convicted of withholding wages from their workers. The database will even show you the exact amount of unpaid wages they owe. If your prospective employer is on this list, do not accept the job under any circumstances.

Summary and Next Steps

Protecting yourself in the Korean job market requires proactive research. Remember to always run these two non-negotiable checks before signing any contract:

1. Verify the Business Number: Use the NTS Hometax site to ensure the company is legally registered and actively paying taxes as a "부가가치세 일반과세자".
2. Check the Labor Blacklist: Search the Ministry of Employment and Labor database to ensure the company has zero history of wage theft or labor abuse.

By taking five minutes to do this research, you can save yourself months of unpaid labor and legal headaches.
