Get a Slovak phone number for your business.

Q: What types of Slovak phone numbers can I register?

We offer two types: 800 toll-free numbers which are free for callers, and local geographic numbers with city-specific area codes such as 02 for Bratislava, 055 for Košice, 051 for Prešov, 041 for Žilina, and 037 for Nitra.

Q: Do I need a local address in Slovakia?

800 toll-free numbers are available with a worldwide address. Local geographic numbers require an address in the number’s area-code zone.

Q: How does the 800 toll-free number work in Slovakia?

An 800 number allows customers to call you for free from any Slovak landline or mobile network. You, as the number owner, cover the call costs. This is widely used for customer service and support lines in Slovakia. Note that 800 toll-free numbers can only be dialed from within Slovakia — they cannot be called from abroad.

Q: What is the format for Slovak phone numbers?

Slovak numbers use the country code +421 . Domestically, all numbers are dialed with a trunk prefix 0 followed by a 9-digit number. Bratislava uses the short area code 02 with an 8-digit subscriber number. Other cities use two-digit area codes like 055 (Košice) or 041 (Žilina) with a 7-digit subscriber number. When advertising internationally, use +421 2 XXXX XXXX for Bratislava (dropping the leading 0). Toll-free numbers are 0800 XXX XXXX domestically or +421 800 XXX XXXX internationally.

Q: Who regulates Slovak telephone numbers?

The Regulatory Authority for Electronic Communications and Postal Services (RÚ) is the national authority responsible for telecoms regulation in Slovakia, including the assignment and oversight of telephone numbers.

Slovak customers call a Slovak number, and that makes a difference to both response and trust. Which number you can have depends on one thing: whether you have an address in Slovakia. Below is what is possible either way.

The question that decides everything

Which Slovak number can your business have?

In Slovakia the regulator decides which Slovak number you can have. Some numbers need your business to have an address in Slovakia; below you can see what is possible for each number.

What a number abroad costs

€49 per monthper number

The same amount in every country — a Slovak number costs no more than a number at home. Including the full phone system: forwarding, IVR menu, call queue, call recording and statistics.

Just testing the market

€250 per yearprepaid

One line, one forwarding number, no features. For anyone who first wants to know whether the phone rings at all before setting up a phone system. That is less than €21 a month — under half the full rate, with exactly one thing that works: the number rings and the call reaches you.

And the call charges

Those depend on where the call goes

A call that arrives in Slovakia and goes on to a VoIP line in your own country costs a different amount from one to a Slovak mobile. You get that rate with your proposal; it is the one thing we cannot put on the page, because it differs per route.

How it works

From request to a ringing phone

You tell us what you need
Which city or which type, and whether you have a Slovak address. If you're not sure, we'll look at it with you.
We check and send a quote
Within one business day you get a proposal with the current rates and an honest answer on whether it can be done. Sometimes the answer is that an 0800 number will serve you better than a local number.
The registration
For local numbers we submit the proof of address to the regulator. That is the only part you have to wait for.
Forwarding to your team
The call arrives in Slovakia and lands with your team, wherever they work. The caller dials a Slovak number and never notices the difference.
