Whether you're managing a new supplier in Bratislava or checking in with a remote contractor in Košice, making international calls to Slovakia can be easier and more affordable than you think — if you know the right steps and tools. 

In this quick guide, we’ll cover how to dial Slovakia correctly from the United States, what the Slovakia country code is, and how modern SMBs can simplify international communication using DialLink’s cloud phone system. 

What’s the Slovakia Country Code? 

The country code for Slovakia is +421. It’s a three-digit number that identifies Slovakia in the international telephone numbering system. Anytime you call Slovakia from outside the country, including from the US, you need to start with this code to ensure your call is properly routed. 

How to Call Slovakia from the US, Step by Step 

Let’s break down the dialing sequence for both landlines and mobile phones: 

For Slovak Landlines: 

  1. Dial 011 – The international exit code from the US. 
  2. Dial 421 – The Slovakia country code. 
  3. Dial the area code – Usually 1 or 2 digits. 
  4. Dial the local number – Typically 6–7 digits. 

Example: Calling a landline in Bratislava would look like 011-421-2-XXXXXXX. 

For Slovak Mobile Phones: 

  1. Dial 011 or use the “+” symbol on mobile. 
  2. Dial 421. 
  3. Dial the mobile number without the leading 0. 

Example: For Slovak mobile number 0903-123-456, dial 011-421-903-123456 or +421-903-123456. 

Pro Tip 

On most smartphones, long-pressing the 0 key brings up the “+” symbol. 

Common Slovakia Area Codes 

Here are some of the most common area codes in Slovakia, along with the locations they correspond to: 

Area CodeRegion

31–37Western regions (e.g., Trnava, Nitra)
41–58Central & Eastern Slovakia (e.g., Žilina, Prešov)
901–949Mobile providers (various carriers)

Use these codes to ensure your call is routed to the correct region. 

When Should SMBs Make International Calls? 

Small businesses and startups commonly call Slovakia for: 

  • Working with remote developers or IT teams 
  • Managing logistics or manufacturing partners 
  • Supporting clients in Central Europe 
  • Exploring business expansion into the EU 

Time zone tip: Slovakia operates on Central European Time (CET), which is typically 6 hours ahead of Eastern Time (ET). 

How Much Does It Cost to Call Slovakia? 

Calling Slovakia using traditional carriers can range from $0.50 to $1.50 per minute. Some services also provide the option to purchase international calling credits or add-ons that reduce the per-minute rate.

How do you call a Slovakia number from the US?

To call Slovakia, dial: 011 + 421 + area code (or mobile prefix) + local number. Omit the initial 0 from Slovak mobile numbers. For example, to call 0903-123-456, dial: 011-421-903-123456.

What is the cheapest way to call Slovakia from the US?

The most cost-effective way is through a VoIP or cloud-based phone system like DialLink, which offers lower international rates than traditional carriers and added advanced call management features.

What is the country code for Slovakia?

How do you add a country code to a phone number?

On a landline, start with 011, then the country code (421), followed by the area code and number. On a mobile phone, use the “+” symbol instead of 011. Always remove the leading 0 from the local number.
