The +421 country code, explained
슬로바키아's international country code is +421. It was assigned by the International Telecommunication Union under recommendation E.164 and is the dialing prefix at the start of every 슬로바키아 phone number written in international format.
You'll often see +421 referred to in search as the "421 area code". Strictly speaking, +421 is a country code — area codes are sub-national, used inside 슬로바키아. The practical meaning is the same: any number starting with +421 or 00421 is a 슬로바키아 number.
