Czech Republic Phone Number Format for Local & International Calls

The key components of the Czech Republic phone number format include the country code, the area code, and the receiver number. Each part has its specific role. Here are more details on them.

The country code is the designated code you must dial when you call any nation from outside its borders. The country code for the Czech Republic is ‘420’, which you must dial when calling the nation from overseas.

Czech numbers use a prefix-based system. There’s no distinct area code to dial separately, unlike many other countries. Also, the landline numbers and mobile numbers use separate prefixes.

Landline Number Prefix

Landline numbers use a regional prefix at the beginning of the phone number for local calls. This prefix is usually a single or double digit (like 2, 3, 4, or 5) and varies by region.

Some Popular Landline Phone Prefixes in the Czech Republic:

Mobile Number Prefix
 

Mobile numbers begin with a three-digit mobile prefix that typically identifies the original mobile operator. These prefixes (like 601, 720, 773, etc.) appear at the start of the phone number and help distinguish mobile lines from landlines.

Mobile Phone Prefixes in the Czech Republic:

Subscriber number is the unique set of digits that is assigned to each phone line. Both landline and mobile numbers are always 9 digits in the Czech Republic. If the number starts with 2-5, it is recognized as a landline number, and if the number starts with 6 or 7, it is a mobile number.

For local calls, the Czech phone number structure consists of 9 digits, which include a regional prefix (for landlines) or a mobile prefix (for cell phone numbers) and subscriber number. Likewise, the toll-free number consists of the toll-free prefix.

Czech landline numbers for local calls are composed of 9 digits, which include the regional prefix and the subscriber’s number. There’s no trunk code (like “0”), and local calls are made using the full number directly.

The Czech mobile phone number structure for local calls consists of 9 digits, including the mobile prefix and the subscriber number. These numbers are easily identified by their starting digits, typically 6 or 7.

Toll-free numbers in the Czech Republic for local calls also consist of 9 digits, starting with a toll-free code (800), followed by a 6-digit subscriber number. These numbers are commonly used by businesses and customer service teams.

The international phone number format for the Czech Republic includes the exit code of your country, followed by the Czech Republic country code, regional/mobile prefix, and subscriber number.

Czech landline numbers for international calls consist of the exit code, Czech country code (+420), followed by a 9-digit number, which includes a regional prefix and the subscriber’s number.

Czech mobile numbers for international calls include the exit code, the Czech country code, followed by a 9-digit mobile number (mobile operator prefix + subscriber number).

Toll-free numbers in the Czech Republic, when dialed internationally, include the exit code, the Czech country code, followed by a toll-free prefix and subscriber number.

Note: When dialing toll-free numbers from abroad, charges may apply depending on the service provider.

Emergency phone numbers in the Czech Republic follow a simple 3-digit structure that can be dialed directly for immediate emergency services. These numbers provide immediate access to critical services such as the police, the fire department, or medical assistance. They’re available 24/7 and are free to call.

When calling the Czech Republic, avoid dialing the wrong phone number format or including the trunk code in the phone number. You must also consider the time differences between your country and the Czech Republic. Otherwise, it may lead to calling at inappropriate hours for the recipient.

A common mistake people make when calling internationally is forgetting to include either the country code or the exit code. You must dial your country’s exit code and the Czech country code before dialing the local number when calling from abroad.

While mobile phones often allow the + sign to replace the exit code, traditional landline phones require the numeric exit code (e.g., 00 in many countries).

Czech phone numbers, whether landline or mobile, do not use a trunk code like 0 in their standard 9-digit format, unlike many other countries. However, some callers mistakenly include a leading 0 when dialing locally or internationally, which can result in a failed call.

The Czech Republic follows Central European Time (CET), which is several hours ahead of countries like the United States. Many people forget to check the time difference before calling.

For example, if you call from the US in the evening, it might be late at night or early morning in the Czech Republic. This often results in missed or unanswered calls. To avoid this, always check the local time and call during regular business or daytime hours.
