What each type means for the caller
- Toll-free: 800
- Free to the caller, usually only from inside the country; the business that owns the number pays for the call. 9 digits after +420.
- Premium rate: 900, 905, 906, 908, 909 or 976
- Charged above a normal call at a rate set by the service, with part of the charge going to the service provider. 9 digits after +420.
- Shared cost: 81, 83 or 84
- The caller pays part of the cost and the owner pays the rest, so the price sits between a free and a normal call. 9 digits after +420.
- Universal access (UAN): 95 or 972–974
- One national number for a business with several sites, routed to the nearest or chosen office. 9 digits after +420.
- Personal number: 700 or 701
- A follow-me number that forwards to whatever phone its owner chooses, so the digits don't reveal the line behind it. 9 digits after +420.
- VoIP: 910 or 970
- Numbers issued for internet telephony services rather than a fixed line or a mobile network. 9 digits after +420.
Writing and dialling a Czech Republic toll-free number
Czech Republic has no trunk prefix, so the number is the same at home and abroad; in E.164 put +420 in front: 800 123 456 becomes +420800123456. Many freephone numbers still only accept calls from inside the Czech Republic, and a call from abroad that does connect is usually charged.
Toll-free and premium numbers in a phone list
In a lead or customer list, a toll-free number usually reaches a company line rather than a person, and a premium-rate number costs you money to call. The free toll-free number checker flags them in a pasted list or CSV, and the Czech Republic phone number format page covers mobiles and landlines.

- Ranges, lengths and examples: Google libphonenumber numbering-plan data (libphonenumber-js 1.13.15), the data our validator uses.
- Official plan: ITU-T E.164 national numbering plan for Czech Rep., which covers Czech Republic. The regulator’s filing is the authority when the two disagree.
The numbering plan only knows what a range was issued for.
In the US and Canada mobiles and landlines share the same prefixes, and anywhere a number can be ported or reassigned the range stops telling the whole story. A live carrier lookup asks the network data instead, which is what Pro + Phone ($49.99/mo) adds.
