Area Code 5451 – Mid-Buda, Sumy

Geographic Overview

The +380 5451 dialing prefix is a geographic National Destination Code (NDC) assigned within the Sumy Oblast of northeastern Ukraine. Specifically, it serves the rural locality of Mid-Buda (also transliterated as Mydbuda or Seredyna-Buda) and its surrounding administrative district. This area lies close to the Russian border, within the historical region of Sivershchyna. The code is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the framework of ITU-T E.164.

Calling Formats

For callers within Ukraine, the national trunk prefix '0' is used, followed by the NDC and the subscriber number. The complete national significant number (NSN) for a Mid-Buda subscriber is 10 digits, formatted as 0 5451 XX-XX-XX. For example, a local number might be dialed as 0 5451 2-34-56 from other parts of Ukraine.

International callers must use the Ukrainian country code +380, drop the leading '0', and dial +380 5451 XX-XX-XX. For instance, from abroad you would dial +380 5451 2-34-56 to reach the same subscriber.

Geographic Allocation and Coverage

This prefix is classified as a geographic number, meaning it is tied to a specific physical location and local loop. The Mid-Buda district is a predominantly rural area, and the subscriber base includes fixed-line residential and business services, as well as some legacy PSTN connections. The code is administered by the Sumy branch of Ukrtelecom, the incumbent operator, though alternative fixed-line operators may also use it for local services.

Dialing Instructions

• Local calls (within Mid-Buda): In most cases, local calls within the same exchange may be dialed using only the subscriber number (XX-XX-XX), but to avoid confusion, it is recommended to use the full national format.
• National long-distance calls (from other Ukrainian cities): Dial 0 5451 followed by the subscriber number. For example, from Kyiv, you would dial 0 5451 2-34-56.
• International calls to Mid-Buda: Dial your country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), then 380 5451 and the subscriber number. For example, from the US, dial 011 380 5451 2-34-56.

Overlays and Numbering Changes

As of the latest updates, there are no overlay codes or mandatory 10-digit dialing changes affecting this area. The Ukrainian numbering plan maintains a closed dialing plan for geographic numbers, meaning the NDC is always required for national calls, even for local calls if dialed from a mobile phone or another fixed line in a different exchange.

For businesses or individuals in Mid-Buda, it is essential to display numbers in international format (+380 5451 ...) on websites and marketing materials to ensure accessibility for international clients and to avoid confusion with other Ukrainian codes.
