How to Call the Czech Republic from the US: A Guide for SMBs and Startups

Let’s say you’re about to connect with a supplier in Prague or follow up with a remote team member in Brno. You pull out your phone — and pause. What’s the correct format to dial a number in the Czech Republic from the US? 

If you’re a small business or startup navigating international communications, this guide is for you. Whether you’re managing distributed teams, coordinating with partners, or expanding your European customer base, we’ll show you how to make high-quality calls to the Czech Republic without draining your budget. 

What’s the Czech Republic Country Code? 

The Czech Republic country code is +420. Anytime you’re dialing a number there from the US, you’ll need to include this code after the international exit code (011). It tells the global phone network that your call is headed to the Czech Republic. 

How to Call the Czech Republic from the US, Step by Step 

Here’s how to dial a Czech phone number correctly from the United States: 

For Czech Landline Numbers: 

1. Dial 011 – the US exit code. 
2. Dial 420 – the Czech Republic country code. 
3. Dial the local landline number – typically 9 digits long. 

Example: If the number is 234 567 890, you would dial: 011-420-234-567-890. 

For Czech Mobile Numbers: 

1. Dial 011 (or use “+” on mobile). 
2. Dial 420. 
3. Dial the mobile number – usually starting with 6 or 7 and 9 digits total. 

Example: If the mobile number is 777 123 456, you would dial: 011-420-777-123-456.  Or on mobile: +420-777-123-456. 

Bonus Tip: 

If you’re using a smartphone, long-pressing the 0 key gives you the “+” sign, which acts as a substitute for the international exit code (011).
