Overview of +420 607
The prefix 607 is a non-geographic mobile network code within the Czech numbering plan, assigned under the country calling code +420. Unlike geographic area codes, 607 does not correspond to a specific city or region; it is used exclusively for mobile services. Numbers with this prefix are part of the national destination code (NDC) 607 and have a total length of nine digits after the country code, following the format +420 607 XXX XXX.
Technical Allocation and Usage
In the Czech Republic, the Telecommunication Office (ČTÚ) allocates number ranges to mobile network operators (MNOs) and mobile virtual network operators (MVNOs). The 607 prefix is currently assigned to a specific operator, but due to mobile number portability (MNP), a subscriber may retain their 607 number even if they switch to a different operator. Therefore, the prefix does not guarantee a particular network; routing is determined by the current operator of the number.
Dialing and Formatting
For international callers, the number must be dialed in full international format: +420 607 XXX XXX (or 00420 607 XXX XXX from countries using the international prefix 00). Within the Czech Republic, callers dial only the nine-digit national number: 607 XXX XXX. There is no trunk prefix (such as '0') used in the Czech Republic; the national significant number (NSN) is nine digits long, starting with 6 for mobile services.
Voice and SMS Routing
Calls and SMS messages to +420 607 numbers are routed over the PSTN and mobile networks. For international SMS, the sender must use the full international format, including the plus sign and country code. The Czech numbering plan supports number portability, so when a number is ported, the routing is updated in a central database to ensure calls and messages reach the subscriber regardless of the original operator.
Practical Considerations
When contacting a Czech mobile number with the 607 prefix from abroad, be aware of potential charges: international tariffs apply, and the receiving party may incur roaming charges if they are outside the Czech Republic. For businesses, it is essential to verify the current operator of a 607 number if you need to confirm network compatibility for services like SMS delivery or call termination. However, for general communication, the number behaves like any other mobile number in the Czech Republic.
