📍 Geographic Location of Vysočina Region
Geographic Coverage and Administration
The +420 56 country-code prefix is a geographic National Destination Code (NDC) assigned to the Vysočina Region (Kraj Vysočina) in the Czech Republic. This administrative region, located in the southeastern part of the country, encompasses districts such as Jihlava, Třebíč, Žďár nad Sázavou, Havlíčkův Brod, and Pelhřimov. The code serves both urban centers and rural areas, with major cities including Jihlava (the regional capital), Třebíč, and Žďár nad Sázavou.
Dialing Formats
Within the Czech Republic, calls to numbers using the 56 prefix require dialing the full nine-digit subscriber number, which includes the NDC. For example, a local call to a fixed line in Jihlava would be dialed as 564 123 456. Internationally, callers must use the Czech country code +420, followed by the nine-digit number, omitting any trunk prefix (the Czech Republic uses no trunk prefix). Thus, the same number would be dialed as +420 564 123 456 from abroad.
Number Structure and Overlays
Czech geographic numbers are nine digits long, including the NDC. The 56 code is subdivided into smaller exchange codes (e.g., 561 for Jihlava, 568 for Třebíč) to route calls efficiently. No overlay codes have been introduced in this region; the 56 prefix remains the sole geographic code for the area. However, number portability allows subscribers to retain their 56 number even if they relocate within the Czech Republic, which may result in a number no longer strictly tied to its original geographic area.
Caller Instructions
- Local callers (within the Czech Republic): Dial the nine-digit number directly, e.g., 564 123 456.
- International callers: Dial the international access prefix (e.g., 00 from most countries), then 420, then the nine-digit number, e.g., 00 420 564 123 456.
- Mobile callers within the Czech Republic can dial the number as they would any domestic fixed-line number.
When calling from abroad, ensure you replace the leading zero (if any) with the +420 country code. For example, if a local number is listed as 0564 123 456, you would dial +420 564 123 456.
Regulatory and Technical Notes
The Czech Telecommunication Office (ČTÚ) oversees the allocation and management of the national numbering plan. The 56 prefix is part of the E.164 international numbering plan, ensuring global interoperability. Calls to 56 numbers are routed via the PSTN and are also accessible through VoIP services that support geographic numbering. Emergency services (112) are reachable from any phone, regardless of the prefix.
