Area Code 31 – Zakarpattia

Geographic Overview

The +380 31 area code is the national destination code (NDC) for the Zakarpattia region (Zakarpatska oblast) in western Ukraine. This geographic code is assigned to fixed-line telephone services within the administrative boundaries of the oblast, with its administrative center in the city of Uzhhorod. The region borders four countries—Poland, Slovakia, Hungary, and Romania—and the code covers both urban and rural subscribers across the oblast.

Coverage and Major Cities

Subscribers within the +380 31 code are located in the following key cities and districts:

• Uzhhorod (the oblast capital)
• Mukachevo
• Khust
• Berehove
• Vynohradiv
• Svaliava
• Rakhiv
• Tiachiv

The code also serves smaller towns and rural communities throughout the region, ensuring comprehensive fixed-line coverage.

Dialing Formats

When calling a fixed-line number in the Zakarpattia region, the dialing format depends on the caller's location.

National dialing (within Ukraine): To call a Zakarpattia fixed-line number from another city in Ukraine, dial the trunk prefix 0, followed by the area code 31, and then the subscriber number. For example, a local number in Uzhhorod might be formatted as:

• 0 31 2 61-23-45 (where '2' is the central office code and '61-23-45' is the subscriber line)

Thus, the complete national number is 0312612345.

International dialing (from abroad): Callers outside Ukraine must use the international access prefix of their country (e.g., 00 from most European countries, 011 from the US/Canada), followed by Ukraine's country code 380, then the area code 31 (without the leading 0), and the subscriber number. For example:

• +380 31 2 61-23-45

So the full international format is +380312612345.

Local and Foreign Caller Instructions

Local callers within Zakarpattia: For calls between different fixed-line subscribers within the same area code, it is often possible to dial only the subscriber number (without the area code) if the call is within the same local calling area. However, for calls to other districts within the oblast, the full national format (0 31 ...) is required. Always check with your local service provider for specific dialing rules.

Foreign callers: When calling from outside Ukraine, always replace the trunk prefix '0' with the country code '+380' and drop the leading '0' of the area code. Ensure you have the correct international exit code for your country.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan updates, the 31 area code is not subject to an overlay. The subscriber number length within the code varies, but the total length of the national significant number (NSN) is typically 9 digits (including the leading '0' for national dialing). The code is exclusively geographic, meaning it is tied to the physical location of the fixed-line connection. Mobile numbers in Ukraine use separate non-geographic codes (e.g., 50, 63, 67, 95, etc.) and are not affected by this area code.

For accurate and up-to-date dialing information, always consult your telecommunications provider or the national regulator, the Ukrainian State Center of Radio Frequencies (UCRF).
