Plug & socket types

Last updated: 20 December 2024

Plug & socket types around the world

There are currently 15 types of domestic electrical outlet plugs in use worldwide, each of which has been assigned a letter by the US Department of Commerce International Trade Administration (ITA), starting with A and moving through the alphabet. These letters are completely arbitrary: they don’t actually mandate anything.
