"Sometimes" means your country uses more than one plug shape and only one of them matches Korea's Type C/F sockets — use the checker above to see your exact result. Select any of the 45 countries above for the full voltage and plug breakdown.
Korea's Power Outlets, Explained
South Korea's electrical grid runs on 220 volts at 60Hz, using Type C and Type F plugs, both of which have two round pins. This standard is shared with most of continental Europe, which is why European travelers rarely need an adapter. Countries that run on 100-127V systems, most notably the United States, Canada, Japan, Taiwan, and parts of Central America, use flat-pin plugs (Type A/B) that will not physically fit Korean sockets, and their appliances are often built for a lower voltage.
Korea standardized on 220V decades ago as part of a national grid upgrade, aligning it with the European convention used across much of Asia today. Hotels in major cities occasionally provide dual-voltage outlets or built-in adapters at the front desk, but it's safest not to rely on this and to travel prepared.
The two prongs of a Type C or Type F plug are round rather than flat, which is the main visual giveaway that your existing charger won't physically fit a Korean wall socket. If you've traveled in continental Europe before and your adapter worked there, the same adapter will almost certainly work in Korea too.
Travel Adapter Tips
What to pack
A single universal travel adapter that supports Type C/F output covers Korea and most of Europe, Southeast Asia, and South America in one device. Look for one with a built-in USB-A/USB-C port so you can skip carrying a separate charger block. If you're traveling with single-voltage appliances (hair tools, small kitchen gadgets), pack a compact step-up voltage converter as well, or plan to buy a dual-voltage version locally.
Ceptics 45W Universal Travel Adapter (Type A/C/G/I, dual USB-C) — a compact, highly-rated option that covers Korea's Type C/F outlets along with most other destinations.

Frequently Asked Questions
Can I use my hair dryer in Korea?
Only if it's dual-voltage (rated 100-240V, usually printed near the plug). Single-voltage hair dryers from the US, Canada, Japan, or Taiwan can be damaged, or pose a fire risk, if plugged into Korea's 220V outlets without a step-up voltage converter. Many travelers just buy a cheap dual-voltage travel hair dryer instead.
Will my phone charger work in Korea?
Almost certainly yes. Nearly all modern phone, tablet, and laptop chargers are dual-voltage (100-240V, 50/60Hz) and work fine in Korea. You'll only need a plug adapter if your home country doesn't already use Korea's Type C or Type F plug.
What type of plug does Korea use?
South Korea uses Type C and Type F plugs, both with two round pins. Type F is more common in hotels and modern buildings, but most Type C plugs fit the same sockets.
What voltage does Korea use?
South Korea runs on 220V at 60Hz, different from countries like the US, Canada, Japan, and Taiwan, which use 100-127V.
Do I need a voltage converter for Korea?
Only for single-voltage appliances from a 100-127V country, such as hair dryers, curling irons, or shavers without a 100-240V rating. Dual-voltage electronics like phone and laptop chargers don't need a converter, only a plug adapter if the plug shape differs.
Can I buy a universal adapter in Korea if I forget one?
Yes. Universal travel adapters are widely available at Incheon and Gimpo airport convenience stores, Daiso branches, and electronics markets like Yongsan.
