Area Code 1716 – Dzerzhinsk

Overview of Area Code +375 1716

Area code 1716 is a geographic National Destination Code (NDC) within the Belarusian national numbering plan, governed by the Ministry of Communications and Informatization of the Republic of Belarus in accordance with ITU-T E.164 recommendations. It serves the city of Dzerzhinsk and the surrounding Dzerzhinsk District, located in the Minsk Region. Dzerzhinsk, formerly known as Koydanovo, is an administrative center situated approximately 30 kilometers southwest of the capital, Minsk. The code is used for fixed-line (PSTN) services, including traditional analog lines and VoIP-based fixed telephony that retains a geographic presence.

Geographic Coverage and Administration

The +375 1716 code covers the urban area of Dzerzhinsk and its adjacent rural settlements within the district. The region is part of the Minsk Region, one of the six administrative regions of Belarus. The code is assigned to the Dzerzhinsk city executive committee and local telecom operators, primarily the national incumbent Beltelecom, which provides local, national, and international fixed-line services. The geographic allocation ensures that calls to this code are routed to the Dzerzhinsk area, regardless of the service provider, as long as the subscriber retains a fixed-line number with a geographic indicator.

Dialing Formats

Understanding the correct dialing format is essential for both domestic and international callers.

• Domestic Calls (within Belarus): When calling a Dzerzhinsk fixed-line number from another Belarusian city or mobile phone, you must dial the trunk prefix 8, followed by the area code and the subscriber number. The format is: 8 1716 XXX-XX-XX. For example, to call a local number 1234567, you would dial 8 1716 1234567.
• International Calls (from outside Belarus): Callers from abroad should dial the international access prefix (e.g., 00 from most countries, or + from mobile phones), followed by the Belarus country code 375, the area code without the leading trunk prefix, and the subscriber number. The format is: +375 1716 XXX-XX-XX. For instance, from the United States, you would dial 011 375 1716 1234567; from the UK, 00 375 1716 1234567.
• Local Calls (within Dzerzhinsk): For calls between fixed-line subscribers within the same local area, it is often possible to dial only the subscriber number (6 or 7 digits) without the area code. However, due to the increasing use of VoIP and mobile networks, it is recommended to always use the full national format (8 1716) to avoid routing issues.

Number Structure and Length

Belarusian geographic numbers consist of a country code (+375), a three-digit area code (or sometimes two-digit for larger cities), and a subscriber number of 6 to 7 digits. For Dzerzhinsk, the subscriber number is typically 6 digits, giving a total length of 12 digits in international format (+375 17 16 XXX-XXX). The area code 1716 is sometimes split as 17 (Minsk region) and 16 (Dzerzhinsk district), but for dialing purposes, it is treated as a single NDC.

Overlay and Numbering Changes

As of the current numbering plan, there is no overlay code for Dzerzhinsk. The area code 1716 is exclusively used for the Dzerzhinsk district. However, the rapid growth of mobile and VoIP services has led to increased number portability. Subscribers may retain their geographic number even if they switch to a VoIP provider, but the number remains associated with the Dzerzhinsk geographic area for routing and emergency services (112).

Caller Instructions

For local callers within Belarus, always include the trunk prefix 8 when dialing from a mobile or from another fixed-line area. For foreign callers, remember to replace the trunk prefix with the international access code and use +375. If you are using a VoIP service, ensure that you have correctly configured the dialing plan to handle international prefixes. When calling from a mobile phone within Belarus, you can also use the international format (+375 1716...) as many mobile networks accept it.
