The next three digits after the country code provide information about the exact location of the number. In 2002 the area codes were standardized:

2 – Prague
31, 32 – Central Bohemian Region
35 – Karlovy Vary Region
37 – Plzeň Region
38, 39 – South Bohemian Region
41, 47 – Ústí nad Labem Region
46 – Pardubice Region
48 – Liberec Region
49 – Hradec Králové Region
51, 53, 54 – South Moravian Region
55, 59 – Moravian-Silesian Region
56 – Vysočina Region
57 – Zlín Region
58 – Olomouc Region

Mobile prefixes are either two or three digits, between the range of 602 to 608 and 72 to 79. However since cell phone numbers can be kept when you change your provider, it is not possible to derive the network provider from the prefix number. If you call a mobile number that is no longer registered with the original provider, you will hear a short message before you are put through. This way you know whether you have to pay more for the call.

The useful telephone service numbers

112 – general emergency number
155 – medical emergencies
150 – fire department
158 – police
154 – towing service
1230,1240 – emergency road service

There are two types of public payphones in the country, those accepting coins, and those accepting telephone cards. Telephone cards can be bought at news stands, post offices, department stores etc. Using public payphones is convenient if you are not staying in the Czech Republic for very long. They are very expensive however if you make international calls. To make international calls from the country you have to dial 00, followed by the appropriate country code. Since international calls are usually very expensive there is a huge number of different calling cards available. These allow you to make relatively cheap phone calls to a specified country.
