The calling codes for the Czech Republic might seem straightforward, but they come with important specifics that are essential for anyone wishing to connect over the phone, whether domestically or internationally. The official country code for the Czech Republic is +420, which you will need to dial after the international access code, often referred to as the international call prefix. Understanding how to use these codes correctly can ensure seamless communication with friends, family, or business associates in this beautiful Central European country.

Calling the Czech Republic from Abroad

If you are situated outside the Czech Republic and wish to make a call, the format you should follow is:

International Access Code (IAC) + Country Code (420) + Nine-digit local number

For example, if you are calling from the United States, you would begin with the IAC 011, then proceed with 420, followed by the nine-digit Czech phone number. In the UK or Ireland, the IAC is 00, so you would dial 00-420 followed by the number. Australians would use 0011-420, while callers from Singapore would initiate the call with 001-420.

It's crucial to note that local Czech numbers do not have an additional trunk prefix or area code when dialed from outside the country. For instance, if a Czech number appears as (0)380 712 651 domestically, you would drop the zero when dialing internationally — thus dialing +420 380 712 651.

Structure of Czech Phone Numbers

Czech phone numbers are comprised of nine digits, encompassing both landline and mobile services within the same numbering framework. Here are some noteworthy aspects to understand regarding Czech phone numbers:

  • Unified Numbering: Unlike many countries, the Czech Republic does not have distinct area codes; the region and operator codes are embedded directly within the nine-digit number.

  • Landline Numbers: Typically begin with digits ranging from 2 to 5, historically linked to geographic regions.

  • Mobile Numbers: Generally begin with a number block from 601 to 799, which helps signal mobile operators. This distinction can also lead to variations in calling rates within the country.

Making Calls Within the Czech Republic

When you are calling someone within the Czech Republic, the process is even simpler. You can just dial the nine-digit number directly — there is no need to prefix it with the country code (+420) or any additional dialing codes. This direct approach streamlines local communications considerably.

While public phone booths have become rare due to the ubiquity of mobile phone usage, major post office telephone offices still exist as a fallback option if you need to place a call.

Special Numbers

In the Czech Republic, toll-free numbers commence with 800, and these calls remain free when dialed from within the country. However, international callers may incur charges, so it's advisable to verify the costs beforehand.

For emergencies, the country follows a brief numbering format for urgent services:

  • 112 – General European emergency services

  • 150 – Fire brigade

  • 155 – Ambulance

  • 158 – Police
