Area Code 177 – Borisov

Overview of Belarus Area Code +375 177

Area code 177 is a geographic National Destination Code (NDC) within the Belarusian numbering plan, assigned to the city of Borisov (also spelled Barysaw) and its surrounding district in the Minsk Region. The code is administered under the national prefix +375, which is the country calling code for Belarus as designated by ITU-T E.164. Calls to this region require the use of the full international format when dialing from abroad, and a trunk prefix 8 when dialing domestically from within Belarus.

Geographic Coverage and Administrative Jurisdiction

Borisov is a significant industrial and cultural center located approximately 70 kilometers northeast of the capital, Minsk. The area code 177 covers not only the city proper but also the Borisov District, which includes smaller towns and rural settlements. The region is part of the Minsk Region (Minskaya Voblasts), but it is distinct from the capital's own area codes (e.g., +375 17 for Minsk city). The administrative jurisdiction falls under the Borisov City Executive Committee, and local telecommunications services are provided by the national operator Beltelecom and other licensed providers.

Dialing Formats and Caller Instructions

To call a fixed-line subscriber in Borisov, the number structure is: +375 177 XXX-XXX (where X represents the subscriber number digits). The total length of the national significant number (NSN) is 9 digits, including the NDC (177) and a 6-digit subscriber number.

• International call from outside Belarus: Dial your country's international access prefix (e.g., 00 from most European countries, 011 from the US/Canada), then 375 (country code), then 177 (area code), then the 6-digit local number. Example: 00 375 177 123456.
• Domestic call from within Belarus (another region): Dial the trunk prefix 8, wait for a dial tone (in some networks), then 0177 (the area code with a leading 0), then the local number. Example: 8 0177 123456.
• Local call within Borisov: In most cases, you can dial the 6-digit subscriber number directly without the area code, but this depends on the operator's local dialing rules. For clarity, always use the full national format when in doubt.

Overlay Considerations and Numbering Plan

As of the latest updates, there is no overlay code for the Borisov area. The 177 code is exclusively assigned to this geographic region. However, the Belarusian numbering plan is managed by the Ministry of Communications and Informatization, and changes may occur. Subscribers in Borisov can keep their numbers when moving within the same area code, but number portability across geographic areas is not generally available for fixed lines. For VoIP and mobile services, the prefix is non-geographic and not tied to Borisov.

Practical Tips for Callers

When calling from a mobile phone, you may need to include the area code even for local calls, as mobile networks often require the full national number. Always verify the current dialing rules with your service provider. For international callers, note that Belarus uses the international dialing prefix +375, and the leading 0 used in domestic dialing is omitted when calling from abroad.
