How to call Slovakia (country code +421)

Calling to Slovakia

  • A leading ‘0’ is not included in the international call sequence – it is only used in Slovakia for domestic long distance calls and domestic calls to a mobile phone.
  • A leading '+' in the phone number means 'dial your country's exit code'.
  • Calling from a mobile phone: dial from on the country where you're currently located.
  • Calling from a VoIP or satellite phone: dial from on the country where the phone is registered.

Slovakia’s country code may be mis-labelled:

  • Country code 00421 (exit code of ’00’ used in many European, Asian, and African nations followed by Slovakia’s country code of ‘421’).
  • Country code 011421 (exit code of ‘011’ used in the United States and Canada followed by Slovakia’s country code of ‘421’).

When calling to a mis-labelled country code, remove the exit code from the call sequence and replace it with the exit code of the country the call is dialed from.
