Do I need a plug adapter in Korea?
Korea vs. Popular Home Countries: Quick Reference
South Korea runs on 220V, 60Hz, Type C/F plugs. Here's how that compares to the countries most visitors to Korea travel from.
| Country | Voltage | Frequency | Plug Type | Adapter Needed? |
|---|---|---|---|---|
| United States | 120V | 60Hz | A/B | Yes |
| Canada | 120V | 60Hz | A/B | Yes |
| United Kingdom | 230V | 50Hz | G | Yes |
| Japan | 100V | 50Hz | A/B | Yes |
| China | 220V | 50Hz | A/C/I | Sometimes |
| Australia | 230V | 50Hz | I | Yes |
| Germany | 230V | 50Hz | C/F | No |
| France | 230V | 50Hz | C/E | Sometimes |
| India | 230V | 50Hz | C/D/M | Sometimes |
| Philippines | 220V | 60Hz | A/B/C | Sometimes |
| Vietnam | 220V | 50Hz | A/C | Sometimes |
| Thailand | 220V | 50Hz | A/B/C/O | Sometimes |
| Singapore | 230V | 50Hz | G | Yes |
| Indonesia | 230V | 50Hz | C/F | No |
| Brazil | 127V | 60Hz | C/N | Sometimes |
"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.
Notice how each socket sits inside a recessed well instead of flush with the surface — that's normal for Korean outlets and power strips, not a defect in this one. It matters because a bulky universal adapter body sometimes can't reach the bottom of that recess: the pins don't seat fully, the connection is loose, or the adapter doesn't go in at all. If yours won't fit, don't force it — a slimmer adapter, or one of the compact Type C/F-only adapters sold locally, will usually clear the recess fine.
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
Just need the plug to fit?
If everything you're bringing is already dual-voltage — true for nearly all phone, tablet, and laptop chargers (check the fine print near the plug for "100-240V") — all you need is something that gets your plug into a Korean socket. A plain, no-frills adapter is smaller than a universal multi-country one, and its slimmer body is more likely to seat fully in Korea's recessed outlets described above. If you're traveling from continental Europe, you likely already own a Type C/F-compatible plug and don't need to buy anything at all.
A basic Type C/F travel plug adapter covers this without paying for USB ports or extra country pins you won't use.
Charging more than one device at once?
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 for your phone. If you're only charging one device, the basic adapter above is cheaper and simpler.

Check the label near the plug first. If it already says "100-240V," a plug adapter alone is enough — skip this. If it lists only a single voltage (110V or 120V), Korea's 220V can damage it without a voltage converter rated for its wattage, not just a plug adapter — dryers and straighteners often draw 1000-1800W, more than small electronics converters are built for. If you'd rather not carry one, a cheap dual-voltage travel hair dryer, or buying one locally at Daiso, is usually simpler than converting your current one.
A 2000W+ step-down voltage converter covers most single-voltage hair tools — check its wattage rating against your device before buying.

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-down 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.
