Czechia country code (prefix) or dialing code with an interactive map and travel information to explore Czechia.
The + initiates an international call, followed by the country code (here 42 for Czechia). Alternatively, in most countries (with some exceptions, for example, USA, Canada, Australia, and Russia) 00 can also be used to initiate a foreign call.
