Jeju Car Rentals: Rules for International Driving Permits (IDP)

Jeju is one of the few places in South Korea where renting a car genuinely makes sense — buses skip most of the coastline, taxis add up fast, and the island’s best spots sit down roads that no tour group visits. But in 2026, one thing still catches international visitors off guard at the rental counter: the IDP rules. Korean rental companies are strict. Show up without the right paperwork and you walk away without a car, regardless of what you booked online. This guide covers everything you need to have in hand before you land at Jeju International Airport (CJU).

Who Can Actually Rent a Car in Jeju

Before worrying about permits, check whether you meet the basic eligibility requirements. Korean rental companies apply these consistently across all major operators in Jeju.

• Minimum age: 21 years old for most standard vehicles. Some companies raise this to 23 or 26 for specific categories like larger SUVs or premium cars.
• Driving experience: At least one year, calculated from the issue date printed on your original domestic license. Premium or larger vehicles often require two to three years.
• Young driver surcharge: Drivers under 25 typically pay an additional fee of around KRW 10,000–20,000 (approx. USD 7–15) per day, depending on the company and vehicle.
• Valid passport: Must cover the entire rental period.
• Original domestic driving license: The physical card issued by your home country. A photo on your phone is not acceptable.
• International Driving Permit (IDP): Mandatory for the vast majority of international visitors. More on this below.
• Credit card in the primary driver’s name: Required for both payment and the security deposit. Debit cards are not accepted for the deposit at most major companies.

All documents must be valid for the full rental duration. If your domestic license expires during your Jeju trip, the rental company will refuse to hand over the keys.

What the IDP Is — and Why Korea Is Strict About It

An International Driving Permit is not a license in its own right. It is a certified translation of your domestic license into multiple languages — including Korean — that allows foreign authorities to verify your driving credentials without a language barrier. It does not replace your home license. It works only when carried alongside it.

South Korea is a signatory to the 1949 Geneva Convention on Road Traffic. This means Korea officially recognises IDPs issued under that convention. IDPs issued under the 1968 Vienna Convention are also accepted. When you present your IDP at a Jeju rental counter, the agent checks that it is current, that the issuing country matches your domestic license, and that it was issued on the basis of the license you are currently holding.

Validity rules in Korea:

• An IDP is typically valid for one year from its date of issue.
• When used in Korea, it is valid for up to one year from your entry date — or until the IDP’s expiry date, whichever comes first.
• If you are staying in Korea for more than one year and want to keep driving, you would need to obtain a Korean driving license. For tourists on a standard trip, this is irrelevant.

The critical point: the IDP, your original domestic license, and your passport must all be presented together. Korean traffic police can ask for all three during a roadside check. Rental companies will not hand over a vehicle unless all three documents are physically in front of them.

How to Get Your IDP Before You Leave Home

This is the part people leave too late. IDPs cannot be obtained in Korea. You must arrange yours before departure, through the officially designated authority in your home country.

• USA: AAA (American Automobile Association) — apply in person at any AAA branch or by mail. Cost is around USD 20. Processing takes a few days in person, longer by mail.
• Australia: NRMA (NSW), RACV (Victoria), RACQ (Queensland), RAA (SA), RAC (WA) — your state’s motoring club. Apply in person for same-day issue.
• UK: Post Office — apply in person at a participating branch. Cost is around GBP 6.
• Canada: CAA (Canadian Automobile Association) — apply through your regional CAA club.
• Japan: Japan Automobile Federation (JAF) — apply in person or by post.
• Germany: ADAC — apply in person at any ADAC branch.

Most IDPs are issued on the same day or within a week. The IDP is valid for one year from its issue date, so there is no benefit to applying months in advance unless your home license itself is close to expiry. Apply no more than a month or two before your trip so you have maximum validity remaining when you land in Jeju.

Bring two passport-sized photos to your appointment — most issuing authorities require them. Some countries now offer online applications, but confirm your country’s process directly with the issuing body, as procedures differ.

Drivers Who Cannot Use an IDP

Not every country has signed the 1949 or 1968 driving conventions. Citizens of countries outside these agreements — including China, Vietnam, and Indonesia — cannot obtain a recognised IDP. This creates a real problem for Jeju car rentals.

The technical alternative for these visitors is a notarised Korean translation of their domestic driving license. In practice, however, the situation is complicated. Most major car rental companies in Jeju — including Lotte Rent-a-Car and SK Rent-a-Car — require either an IDP or a Korean driving license. They do not typically accept certified translations from international tourists as a standalone document. This effectively makes it difficult for visitors from non-convention countries to rent a car through standard commercial channels.

If you hold a license from China, Vietnam, Indonesia, or another non-convention country, your options in 2026 are limited:

1. Contact specific local Jeju rental companies directly (in Korean, ideally) before your trip to ask whether they accept notarised translations. Smaller operators occasionally have more flexibility.
2. Use Kakao Taxi or hire a private driver for the day instead — this is increasingly popular with Chinese visitors to Jeju and works well for covering the main highlights.
3. Consider a combination of the public Jeju intercity bus network for major routes and taxis for final-kilometre access to remote spots.

Step-by-Step: Booking and Picking Up Your Rental in Jeju

Step 1: Pre-book — do not skip this

Jeju’s rental car supply tightens dramatically during peak periods: summer (July–August), Chuseok, Lunar New Year, and spring blossom season (late March–April). In 2026, dynamic pricing means leaving your booking to the last minute can easily double the daily rate. Aim to book at least four to six weeks ahead for peak dates.

Where to book:

• Lotte Rent-a-Car (www.lotterentacar.net) — largest fleet in Korea, English booking portal available.
• SK Rent-a-Car (www.skrentacar.com) — second largest, reliable service and English support.
• Klook (www.klook.com), Creatrip (www.creatrip.com), Trazy (www.trazy.com) — international aggregators that bundle Jeju rentals. Good for price comparison and English-language booking flows.
• Socar (www.socar.kr) and Green Car (www.greencar.co.kr) — app-based car-sharing services. Technically usable by international visitors with a valid IDP, but registration requires a Korean phone number and local payment method. The apps remain primarily in Korean in 2026, making them less accessible for first-time visitors.

During pre-booking, you will be asked for your IDP number, domestic license number, and passport number. Have all three ready.

Step 2: Airport pickup

Most major rental companies have counters inside or directly adjacent to Jeju International Airport (CJU). Many operate shuttle buses to their main depots, which are typically five to ten minutes from the terminal. Follow the “Rent-a-Car” signs after baggage claim — they are in English.

At the counter, hand over your passport, original domestic license, and IDP simultaneously. The agent will verify all three against your booking details. This takes about five minutes if everything matches. Any discrepancy — a name transliteration difference, an expired IDP, a missing original license — will halt the process.

Step 3: Security deposit and contract

The security deposit is authorised (not charged) on your credit card. Expect KRW 200,000–500,000 (approx. USD 150–370) depending on the vehicle class. This hold is released when you return the car in satisfactory condition. Read the rental agreement before signing, particularly the sections on fuel policy and insurance coverage limits.

Vehicle Inspection and What to Watch Before You Drive Off

This step is where disputes start if you skip it. Before accepting the keys, walk around the car with the rental agent and check for existing damage: scratches along the door sills, scuffs on bumpers, chips in the windshield. In bright Jeju sunlight, even minor paint damage is visible.

• Take a short video walking around the entire car, including the roof, before getting in.
• Confirm that every mark visible in your video is documented on the rental agreement. Get the agent to initial next to any additions.
• Check the tires — note any existing wear or damage, as tires are often excluded from CDW coverage.

If you are renting an electric vehicle (EV) — increasingly common in Jeju in 2026 as fleets expand — also note the battery charge level at pickup and confirm what the agreed return charge level is. Check that the charging cable is in the boot and undamaged. Ask the rental agent to show you the nearest fast-charger locations on a map; Jeju has reasonable EV charging infrastructure but coverage at remote trailheads is patchy.

Driving in Jeju: Road Rules, Navigation Apps, and Fuel

Korea drives on the right side of the road. Traffic signs use international symbols, and most major tourist-route signs also appear in English. A few rules catch international drivers out:

• Speed limits: 30–50 km/h in urban areas, 60–80 km/h on rural roads, 80–100 km/h on expressways. Speed cameras are frequent and automated fines are sent to the rental company, who charge them to your card.
• Right turn on red: Permitted after a full stop, unless a sign prohibits it — but yield fully to pedestrians and oncoming traffic before proceeding.
• Bus lanes: Yellow-marked lanes on main roads are bus-only during specified hours. Driving in them outside those hours is fine; inside those hours it is a fineable offence.
• Tolls: Jeju Island has no toll roads. This simplifies everything — no Hipass transponder needed, no cash worries at booths.

For navigation, skip the built-in GPS unit offered by the rental company. They run in Korean and update slowly. Use your smartphone instead.

• Kakao Navi (카카오내비): The best option. Real-time traffic, speed camera alerts, parking availability at major Jeju sites, and solid English support in 2026. The sound of the turn-by-turn voice prompt through your phone speaker feels reassuringly clear even on winding Hallasan approach roads.



• T-Map (티맵): Strong alternative, also with real-time traffic and English mode.
• Naver Map (네이버 지도): Better for searching restaurant or café names than for turn-by-turn driving.

Download Kakao Navi and T-Map before boarding your flight to Jeju. Offline caching ensures they work in areas with weak signal near Hallasan’s summit trails.

Most Jeju gas stations operate on a full-to-full fuel policy. Return the car with a full tank. Petrol stations are plentiful on the main Jeju coastal road (1132 Route) and in Jeju City and Seogwipo. Unleaded petrol runs approximately KRW 1,700–1,850 per litre (approx. USD 1.26–1.37 per litre) in 2026.

2026 Budget Reality: What Car Rentals Actually Cost in Jeju

All prices below use an exchange rate of 1 USD ≈ 1,350 KRW.

Daily rental rates

• Budget — Compact car (Kia Morning, Hyundai Casper): KRW 30,000–60,000 (USD 22–45) low season / KRW 50,000–100,000+ (USD 37–75+) peak season.
• Mid-range — Mid-size sedan (Hyundai Avante, Kia K3): KRW 40,000–80,000 (USD 30–60) low season / KRW 70,000–150,000+ (USD 52–110+) peak season.
• Comfortable — SUV (Kia Seltos, Hyundai Tucson): KRW 60,000–120,000 (USD 45–90) low season / KRW 100,000–200,000+ (USD 75–150+) peak season.

Insurance

• Basic mandatory cover: Included in the base rental fee. Covers third-party liability up to a defined limit only.
• Standard CDW: KRW 10,000–20,000/day (USD 7–15). Reduces your liability for damage to the rental car but leaves a deductible of KRW 100,000–500,000 (USD 75–370).
• Super CDW / Full coverage (zero deductible): KRW 20,000–40,000+/day (USD 15–30+). Highly recommended. Read the fine print — tires, wheels, and undercarriage damage are typically excluded even from full coverage packages.

Add-ons

• GPS unit (if not using your phone): KRW 5,000–10,000/day (USD 4–7).
• Child or booster seat: KRW 10,000–20,000/day (USD 7–15), usually capped for longer rentals.
• Young driver surcharge (under 25): KRW 10,000–20,000/day (USD 7–15).

Parking

Many natural attraction car parks in Jeju are free or low-cost. Downtown Jeju City and Seogwipo paid lots typically charge KRW 1,000–2,000/hour (USD 0.75–1.50), with daily maximums at larger facilities. Popular coastal spots like Hyeopjae Beach and Jeongbang Waterfall have paid lots that fill up early on summer mornings.

Common Mistakes That Get Tourists Turned Away at the Counter

These are not edge cases — rental staff in Jeju report seeing all of these regularly:

1. Bringing only the IDP, no original license. The IDP is meaningless without the original domestic license beside it. Both must be physical documents.
2. Assuming a digital or smartphone IDP will be accepted. As of 2026, physical IDPs are required by Korean rental companies without exception. There are no pilot programs for digital IDP acceptance at commercial rental counters.
3. Presenting a domestic license from a different country than the IDP. If your IDP was issued in Australia but you are now a UK license holder, it is invalid. The issuing country must match the license country.
4. Using a debit card for the security deposit. Virtually all major Jeju rental companies require a credit card — not a debit card — for the deposit hold. Bring a credit card in the primary driver’s name.
5. Booking for one driver but a partner wants to drive. Additional drivers must be registered at the counter and their documents verified. This usually costs KRW 5,000–10,000 per additional driver per day. Do not let an unregistered person drive — insurance is void.
6. Returning the car on empty. The full-to-full fuel policy is standard. Rental companies charge a significant premium to refuel on your behalf — often well above the pump price.
7. Skipping the pre-return inspection photos. Before returning, photograph the car again from all angles. This protects you if the company later claims damage occurred during your rental.

Frequently Asked Questions

Do I need an IDP to rent a car in Jeju if my license is in English?

Yes. Even if your domestic license is printed in English, Korean rental companies require an IDP for non-Korean license holders. The IDP requirement is based on national convention rules, not on whether your license is legible in Korean. An English-language license alone is not sufficient at any major rental company counter in Jeju in 2026.

Can I get an IDP after arriving in South Korea?

No. IDPs must be obtained in your home country through the officially designated motoring authority before departure. There is no facility to issue an IDP inside South Korea for foreign visitors. If you arrive without one, you cannot legally rent or drive a car in Jeju.

How far in advance should I book a rental car in Jeju?

For travel during peak periods — July, August, Chuseok, Lunar New Year, and late March to mid-April — book four to six weeks ahead at minimum. In 2026, dynamic pricing means late bookings during peak season can cost two to three times the standard daily rate, and inventory genuinely runs out for popular vehicle categories.

Are electric vehicles available to rent in Jeju, and do IDP rules still apply?

Yes to both. EV fleet availability expanded significantly in Jeju by 2026, with models from Hyundai and Kia available at major rental companies. The same IDP, original license, and passport requirements apply regardless of whether the vehicle is petrol, diesel, or electric. Ask about charging infrastructure when you pick up the car, as coverage at remote sites varies.

What happens if I am stopped by police without my IDP?

Driving without a valid IDP — even with your original domestic license — constitutes unlicensed driving under Korean law. You could receive a fine, and your rental insurance may be voided if an accident occurs. Korean traffic police conduct roadside checks, particularly around popular Jeju tourist areas. Always carry all three documents: passport, original domestic license, and IDP, together in the car.
