Telephone numbers in the Czech Republic

From Wikipedia, the free encyclopedia

Following the break-up of Czechoslovakia in 1993, the successor states, the Czech Republic and Slovakia, continued to share the 42 country code, until 1997, with the Czech Republic adopting 420 and Slovakia adopting 421.

Country Code: 420


On September 22, 2002, the Czech Republic adopted a closed numbering plan, with nine-digit numbers used for local and national calls, and the dropping of the trunk code 0.

Before the change, the following arrangements would have been made for calls to Brno:

Local call:         xx xx xx xx
National call:      05/xx xx xx xx
International call: +420 5 xx xx xx xx

After the change, the dialing arrangements for calls to Brno were as follows:

Within Czech Republic:  5xx xxx xxx
Outside Czech Republic: +420 5xx xxx xxx

In the case of mobile numbers, which had to be dialed in full, the only change was that the 0 was no longer used:

Within Czech Republic:  602 xxx xxx 
Outside Czech Republic: +420 602 xxx xxx

[edit] Emergency calls

  • Ambulance: 155 or 112
  • Police: 158 or 112
  • Fire brigade: 150 or 112
  • Municipal police: usually 156 or 159 (not universally available)

These numbers are always toll-free.

[edit] Prefixes

The first 1-3 digits (after +420) of the telephone number can indicate location or network. Note: As the subscriber can retain his/her telephone number when he/she decides to change the operator, this division may not be 100% true. If you have a mobile starting for example with 73 and you decide to quit your contract with T-mobile and reassign your number to, let's say, Vodafone, then a short voice message in Czech and English is played to those who call you, stating "you are calling out of a T-mobile network" before ringing tone.
