Slovakia phone numbers — common questions
What is the country code for Slovakia?
The international dialling code for Slovakia is +421. A virtual Slovakia number is issued inside that numbering plan, so it appears as a local number to anyone calling or texting from within the country.

Do I need an office in Slovakia to get the number?
You do not need a physical office, but you do need a company registered in Slovakia. When registering the number you provide its address in Slovakia. The number itself is virtual — it routes to your PBX phone system, 3CX or SIP setup.

The number handles voice calls — inbound and outbound — and can receive WhatsApp calls. Inbound SMS is not available in this country.
