Overview of Slovakia's +421 902 Mobile Prefix
The +421 902 prefix is a non-geographic mobile network code assigned within Slovakia's national numbering plan, as governed by the Regulatory Authority for Electronic Communications and Postal Services (RU). Unlike geographic area codes that correspond to specific cities or regions, 902 is location-independent and exclusively used for mobile services. This prefix is part of the 90x series, which is allocated to mobile network operators (MNOs) and mobile virtual network operators (MVNOs) operating in Slovakia.
Technical Formatting and Dialing Procedures
Slovak mobile numbers, including those beginning with 902, follow the ITU-T E.164 international standard. The full international format is +421 902 XXX XXX, where '902' is the national destination code (NDC) and the remaining seven digits constitute the subscriber number. When dialed domestically, the leading '0' trunk prefix is used: 0902 XXX XXX. For callers from abroad, the international access prefix (e.g., 00 or +) is followed by the country code 421, then the NDC without the leading zero, and the subscriber number.
Example: A Slovak mobile number might be +421 902 123 456. From within Slovakia, you would dial 0902 123 456. From the United States, you would dial 011 421 902 123 456, while from most European countries, you would dial 00 421 902 123 456.
Number Portability and Routing
Slovakia implemented mobile number portability (MNP), allowing subscribers to retain their 902 numbers when switching operators. Consequently, the prefix does not indicate a specific carrier; it merely identifies the original allocation range. Routing is determined by a central database, ensuring calls and SMS are delivered correctly regardless of the current network.
Usage and Services
Numbers under 902 are used for voice calls, SMS, MMS, and mobile data services. They support standard GSM/UMTS/LTE/5G technologies. As with all Slovak mobile numbers, calls to 902 numbers may incur charges depending on the caller's plan and the subscriber's roaming status. International SMS and voice routing follow standard interconnection agreements.
Regulatory and Dialing Considerations
There are no geographic restrictions for 902 numbers; they can be used anywhere in Slovakia. When dialing from abroad, always omit the initial '0' of the domestic trunk prefix. Ensure you use the correct international exit code for your country. For emergency services, always dial 112 or the local emergency number, regardless of the prefix.
