Area Code 3131 – Mukacheve, Zakarpattia

Geographic Overview

The +380 3131 prefix is a geographic National Destination Code (NDC) assigned to the city of Mukacheve and its surrounding areas within the Zakarpattia Oblast of western Ukraine. This region, historically known as Transcarpathia, borders Hungary, Slovakia, Poland, and Romania, and Mukacheve serves as a significant economic and cultural hub in the area. The code is used for fixed-line (PSTN) services, connecting subscribers within the city limits and adjacent rural communities that fall under the same local exchange area.

Dialing Formats and Instructions

For callers within Ukraine, the national trunk prefix '0' is used before the area code, followed by the subscriber number. The complete national format is 0 3131 XXX-XX-XX (where X represents digits of the local subscriber number, typically 7 digits). For example, a local number might be dialed as 0 3131 123-45-67.

For international callers, the country code +380 is used, followed by the area code without the leading '0'. The international format is +380 3131 XXX-XX-XX, e.g., +380 3131 123-45-67. When dialing from abroad, you must replace the trunk prefix '0' with the international access code of your country (e.g., 00 from most European countries, 011 from North America) and then dial 380 3131...

Administrative and Jurisdictional Notes

Mukacheve is a city of oblast significance, and its telephone numbering is administered under the National Commission for State Regulation of Communications and Informatization (NCCIR) of Ukraine. The geographic allocation means that numbers with this prefix are tied to the physical location of the fixed line. As of recent years, Ukraine has implemented number portability for fixed lines, allowing subscribers to retain their numbers when changing operators within the same geographic area, but the prefix generally remains associated with the Mukacheve region.

Overlay and Future Considerations

Currently, there is no overlay code for Mukacheve; the 3131 prefix serves as the primary geographic code for the area. However, as with many regions, the demand for new numbers may lead to the introduction of additional codes in the future. For now, callers should continue to use the existing format. It is also important to note that while VoIP services may allow users to obtain numbers with this prefix, the geographic association remains for routing and emergency services purposes.
