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 xxAfter the change, the dialing arrangements for calls to Brno were as follows:
Within Czech Republic: 5xx xxx xxx Outside Czech Republic: +420 5xx xxx xxxIn 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 xxxEmergency calls (always toll-free)
Prefixes
The first 1-3 digits (after +420) of the telephone number indicates location or network. For mobile phones, since there is number portability, the mobile phone code only indicates the original operator. For example, when a person calls a number starting with 73 (T-mobile) but had been ported to another operator, a short voice message in Czech and English is played stating "you are calling out of a T-mobile network" before the ringing tone.
