How the Plug and Socket Types by Country works
This table of plug types by country lists the sockets, mains voltage and frequency used in 228 countries and territories. Search a country before a trip to see which travel adapter to pack, or search a type such as G or a voltage such as 120 V to see everywhere it is used.
How to read the plug types by country table
Plug types use the lettering popularised by the IEC, from Type A, the two flat pins used in North America and Japan, to Type O in Thailand. Where a country uses several types, all are listed, most common first. Voltage is the nominal supply voltage, shown as the single-phase figure followed by the three-phase figure where the source gives both, and frequency is 50 or 60 Hz.
Adapter or converter
An adapter only changes the shape of the pins, so it is enough when your device runs on the local voltage. Most phone chargers, laptop bricks and camera chargers are marked 100–240 V and 50/60 Hz and need nothing more. A hair dryer, kettle or other heating appliance built for 120 V will burn out on 230 V, so it needs a voltage converter or a dual-voltage model.
Why frequency matters less than voltage
Nearly all modern electronics run on either 50 or 60 Hz. The difference shows up in older mains-synchronised clocks, some motors and turntables, which run fast or slow on the wrong frequency. Japan is split, with 50 Hz in the east and 60 Hz in the west, which is why it is listed with both.
FAQ
Which plug type does the UK use?
The United Kingdom uses Type G, the three rectangular-pin plug defined by BS 1363, at 230 V and 50 Hz. Types D and M survive for older round-pin circuits and lighting, and bathrooms may have a shaver socket that takes two-pin plugs.
Do I need a converter for the US or only an adapter?
The United States runs at 120 V and 60 Hz with Type A and B sockets. Anything marked 100–240 V, such as most chargers, only needs a plug adapter; a single-voltage 230 V appliance needs a step-up converter to work there.
Where does this plug type data come from?
It is taken from the Wikipedia table Mains electricity by country, which cites national standards bodies and the IEC World Plugs list, and was retrieved on 30 September 2026. It is shared under CC BY-SA 4.0, so reuse of the download must carry the same licence.
Can I download the plug types by country list?
Yes. The CSV and JSON buttons give you all 228 rows with the country, plug types, voltage, frequency and national standard, ready for a travel checklist, a spreadsheet or a product listing that ships worldwide.
