Is my Jeju private car legal? Plates, rentals and travel agencies explained

Step 1: read the licence plate

Korean plates show the vehicle's use in the Korean letter in the middle (for example 12하 3456).

• Yellow plate, letter 바 / 사 / 아 / 자: a commercial passenger vehicle (taxi, licensed charter). These are allowed to carry paying passengers.
• White plate, letter 하 / 허 / 호: a rental car. Whether the ride is legal depends on who rented it — see step 2.
• White plate, any other letter: a private car. Paid passenger transport in a private car is banned (Passenger Transport Service Act, Art. 81).

Ask the operator for the plate number before the trip, and check it again when the car arrives.

Step 2: rental car with a driver — when is it legal?

Korean law does not let rental cars be used to carry paying passengers, and normally bans rental companies from supplying drivers (Art. 34). There is an exception: a rental company may arrange a driver for certain renters, and foreign visitors are one of them. Separate rules allow drivers for 11 to 15-seat vans rented for tourism (6 hours or more, or to and from an airport or port).

So a legal set-up looks like this:

• The rental contract is in your name (or your group's), signed with a licensed rental company.
• The driver is arranged by that rental company.

It is illegal when the operator or driver rents the car in their own name and then charges you for the ride, or when a rental company carries paying passengers itself.

Step 3: booking through a travel agency

Many Jeju charters are sold by travel agencies on Xiaohongshu or WeChat. The agency itself must be a registered travel business (Tourism Promotion Act). Then check the car:

• Agency rents a car in its own name, adds a driver and charges you: illegal.
• Agency uses a private car: illegal — including the common line "the car is free, you only pay for the guide".
• Legal options: a yellow-plate licensed vehicle, or a rental contract in your own name with the driver arranged by the rental company.

If the agency can't show you which of these it is, treat it as a risk.

Why it matters to you

• Insurance: ordinary private or rental car insurance may not cover paid passenger transport. In an accident, you could be left without compensation.
• Trips cut short: Jeju police and city officials run joint checks at tourist spots. If the car is stopped, your day can end there.
• Penalties for operators: illegal paid transport can bring up to 2 years in prison or a 20 million KRW fine, and running an unregistered travel business up to 3 years or 30 million KRW (as reported by Korean media).

In May 2026 Jeju police reported a group that recruited tourists on Chinese social media and drove them in ordinary rental cars, charging 20,000–30,000 KRW per person.
