The table below summarises the plug types, voltage and frequency of electrical current in both Korea, North and Yemen.
| Korea, North | Yemen | |
|---|---|---|
| Plug Types | C | A, D, G |
| Voltage | 220V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Korea, North uses Plug Type C.
In Yemen there's more than one socket type in use. You may require more than one adaptor.

The voltages found in Korea, North (220V) and Yemen (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Korea, North and Yemen is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
