    Technical info on Czech phone numbers

    • In the Czech Republic, phone numbers follow the E.164 international numbering plan, as is the case in most countries.
    • Country code:
    • The Czech Republic's country code is +420. When dialing from abroad, you need to prefix the local number with this code.
    • Area codes: 2-3 digits
    • Area codes in the Czech Republic can be either two or three digits long. They are used to identify specific geographic regions or certain types of services.
    • Local numbers: 7-8 digits
    • Local phone numbers in the Czech Republic are typically seven or eight digits long, depending on the area code. When combined with the area code, the total number of digits (excluding the country code) is nine.
    • Number format:
    • +420 ABC DEFGHI (8-digit local number) or +420 AB CD EFGH (7-digit local number)
    • Phone numbers in the Czech Republic are usually written with a space separating the area code from the local number, and with additional spaces within the local number for easier readability.
    • Mobile numbers: Start with 6 or 7
    • Mobile phone numbers in the Czech Republic usually start with a 6 or 7, followed by eight more digits. There is no specific area code for mobile numbers, as they are not tied to a particular geographic region.

    The history behind Czech phone numbers

    • The history of phone numbers in the Czech Republic can be traced back to the early 20th century when telephone networks began to be established in the country. The Czech Republic, formerly part of Czechoslovakia, has had its own telecommunication system and numbering plan since gaining independence in 1993.
    • Early telephone networks (1900s-1940s):
    • The first telephone lines in Czechoslovakia were installed in the early 1900s. Telephone numbers were short, typically consisting of only 2-4 digits, and were often assigned based on the subscriber's location or occupation.
    • Nationalization and growth (1940s-1980s):
    • After World War II, the government nationalized the telecommunication industry, leading to significant growth in telephone infrastructure. The numbering plan was expanded, and phone numbers began to include an area code to identify the geographic region of the caller.
    • Independence and the new numbering plan (1993-present):
    • Following the split of Czechoslovakia into the Czech Republic and Slovakia in 1993, both countries established their own numbering plans. In the Czech Republic, a new numbering plan was introduced in 1996, featuring a 9-digit format (including the area code). The format is usually written as +420-XXX-XXX-XXX, where +420 is the country code for the Czech Republic, followed by the area code and the local number.
    • Introduction of mobile phone numbers:
    • With the advent of mobile phone technology in the late 1990s, new number ranges were allocated for mobile networks. Czech mobile phone numbers generally start with a 7, followed by 8 digits, although other formats may also be used.
    • Number portability:
    • In 2006, number portability was introduced in the Czech Republic, allowing users to switch between mobile and landline operators without changing their phone number.
    • Short codes and special numbers: The Czech Republic also has short codes and special numbers for various services, such as emergency services (e.g., 112 for general emergencies), information services, and premium rate services.

    Please read if you make EU to EU connections

    Jul 19, 2016

    This only applies if you forward your European FlyNumber to a European regular phone number and or make outgoing calls from your EU FlyNumber to an EU number

    Anytime our system needs to make an EU to EU connection via POTS/PSTN ( Regular phone numbers) you pay this rate.

    Otherwise, it’s the regular per min rates - you’re never charged both rates, it’s one or the other.

    Or If you have a European FlyNumber and are calling European phone numbers

    Example: If you buy a UK FlyNumber and forward the calls to a European phone number -this applies.

    Example: Call from UK caller > UK FlyNumber > Euro Phone number . The rate you would want to look up is for the " Euro phone number "

    Example: If you have a Ireland FlyNumber and call a UK Mobile number, you would pay the UK mobile rate found below

    Luxembourg or Czech number to call into Germany

    Jul 12, 2021


    I won’t be able to qualify for a German number but I want to call into Germany for as cheap as possible to look for a job. I am currently in Canada

    I see this:

    However, I don’t think this applies if I buy a Czech number from FlyNumber and then call into Germany. So my primary question is what is cheapest way of going about calling into Germany for me?

    Here are some other questions too please:

    1. What are the setup costs
    2. what are the fixed monthly costs
    3. what are the costs of inbound calls (call setup, p/minute)
    4. what are the costs of outbound calls (call setup, p/minute)
    5. how much time does it take to setup the service
    6. what is the contract duration and contract cancellation policy
    7. can i keep the virtual number if i decide to switch providers?

    Thank you

    NYC phone numbers -Inside scoop

    Nov 01, 2022

I’ve been outside the city for a while now so […]

I personally was always attracted to grids, so anytime I got to use them, for example- in school or other places , I was always delighted. Then, around 2012 we released […]
