Plan smarter, travel better.
How to use this for your Korea trip
- Download essential apps like Naver Map for navigation, Kakao T for ride-hailing/taxi, and Papago for translation before you arrive. Google Maps has limited functionality in Korea.
- Acquire a Wowpass card or T-Money for public transport and small purchases. Wowpass offers currency exchange, payment, and ATM functions, while T-Money is primarily for transport and some retail. Both are top-up cards.
- Be aware of the night taxi surcharge, which typically applies between 22:00 (10 PM) and 04:00 (4 AM). Fares can increase by 20-40% during these hours.
- Utilize instant tax refunds at participating stores like Olive Young for purchases between 15,000 KRW and 1,000,000 KRW. Present your passport at checkout to claim the refund immediately.
- For longer layovers or large luggage, consider T-Luggage services at major stations (e.g., Seoul Station) or airport facilities. T-Luggage at Seoul Station operates from 09:00 to 22:00 daily.

Frequently asked questions
Can I use my international credit card everywhere in South Korea, and what about cash?
Major credit cards (Visa, Mastercard) are widely accepted. However, for public transport top-ups (T-Money/Wowpass) or small vendors, cash is often needed. Subway station top-up machines frequently only accept cash. It's wise to carry some 10,000 KRW notes.
What time does the late-night taxi surcharge start in Korea?
The late-night taxi surcharge in South Korea typically begins at 22:00 (10 PM) and lasts until 04:00 (4 AM). During these hours, the fare can increase by 20% to 40%, depending on the city and specific taxi type.
How do I get a tax refund for my purchases at Incheon Airport?
For purchases eligible for tax refund (over 15,000 KRW from participating stores), complete the refund process at a Kiosk or tax refund counter at Incheon Airport before checking in your luggage if you need to show items. Kiosks are abundant in both terminals (T1 and T2) before security checks, and staff are available for assistance.
Which local apps are essential for tourists in Korea?
For navigation, Naver Map or Kakao Map are crucial as Google Maps has limited functionality. Kakao T is essential for taxis and ride-hailing. Papago is the best translation app. For food delivery, Baedal Minjok (Baemin) is popular, and KakaoTalk is the primary messaging app for communicating with locals and businesses.
What are the rules for liquids in carry-on baggage at Korean airports?
Liquids, aerosols, and gels in carry-on baggage are restricted to containers of 100ml or less. All these containers must fit comfortably within a single transparent, resealable plastic bag of 1-liter capacity (approximately 20cm x 20cm) per passenger. Exemptions apply for baby formula/food and essential medicines.
