Slovakia – Country Code 421

LAST UPDATE: February 12th, 2020

Calling to Slovakia

  • Do not include a leading ‘0’ 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 mislabeled:

  • 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 mislabeled 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.

… to a mobile (cellular) phone or text (SMS)

Use the same call sequence.

Mobile phone numbers are represented by phone numbers starting with ‘901’ through ‘959’ inclusive.

When calling a mobile phone user, dial to the country where the mobile phone is registered, regardless of where the person is roaming.
