Electricity & Voltage
The standard voltage in Korea is 220 volts (and 60 Hertz, or cycles), and the outlet has two round holes. If you do not have a multi-voltage travel adapter, you can borrow one from your hotel’s front desk for free of charge (however, some establishment may request a minimal fee as deposit, covering for possible loss). If you would like to purchase one in Korea, you can find them at the airport, any of the retail stores, major duty-free shops, convenience stores or even stationery stores.

Currency, Credit Cards, & Traveler’s Checks

Korea’s official monetary unit is the won (KRW). When you need to exchange your foreign currency into Korean won, visit a bank, exchange service center, or an authorized exchange. (Bank business hours: 09:00-16:00, closed on Saturdays, Sundays and public holidays.)

Most of the businesses in Korea widely use and accept payment by credit cards, including at major hotels, department stores, large restaurants and stores. Visa, MasterCard, American Express and other credit cards can be used.

Traveler’s checks can be exchanged for cash at banks or exchange booths. A number of stores still accept the checks instead cash. Nonetheless, the forms of credit cards and debit cards have become a more preferred means of payment by travelers. Thus trading checks is hardly observed nowadays as there is seemingly a decreasing number of stores that offer this service.

Tax and Tipping

Korea’s Tax Free System can largely be divided into “Duty Free” and “Tax Refund.” In Duty Free shops, no tax is applied to the price of the items, including Value Added Tax (VAT) and Individual Consumption Tax. These stores are generally operated by large department store chains located in airports and downtown.

Tax Refund refers to shops that apply a tax to the items and after purchasing at the full price, tourists can apply for a refund of the taxes paid before leaving the country. In general, tax refunds can be received by submitting the receipt at the proper tax refund booth when leaving the country. However, from January 1, 2016, tourists can receive an immediate tax refund below a certain limit when shopping at certified Tax Free stores. Starting at department stores and marts where foreigners typically shop, the immediate tax refund system is expanding to all Tax Free shops. You can get a refund for 10% of your purchasing price.
