Area Code 5756 – Krasnokutsk, Kharkiv

Overview of Area Code 5756

Area code 5756 is a geographic National Destination Code (NDC) within the Ukrainian public switched telephone network (PSTN), allocated to the town of Krasnokutsk and its surrounding administrative district in the Kharkiv Oblast (region) of eastern Ukraine. This 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. The geographic area served by 5756 is primarily rural, with Krasnokutsk acting as the administrative center. The code covers the settlement and nearby villages within the Krasnokutsk Raion, which is situated approximately 100 kilometers northwest of the city of Kharkiv.

Dialing Formats and Usage

For callers within Ukraine, the national trunk prefix 0 is used before the area code. Thus, to call a fixed-line subscriber in Krasnokutsk, you dial: 0 5756 XX XX XX (where X represents the subscriber's local number). For international callers, the Ukrainian country code +380 replaces the trunk prefix, so the international format becomes: +380 5756 XX XX XX. For example, a local number might be formatted as 0 5756 2 34 56 domestically and +380 5756 2 34 56 from abroad. It is important to note that the total number of digits after the country code is 9, which is standard for Ukrainian fixed-line numbers. The subscriber number length within the 5756 area is typically 5 to 7 digits, depending on the specific exchange capacity.

Geographic and Administrative Context

Krasnokutsk is a small urban-type settlement with a population of around 7,000 residents. The area code 5756 is assigned to the local telephone exchange that serves the town and the surrounding rural communities. The Kharkiv region is known for its industrial and agricultural significance, but Krasnokutsk itself is primarily agricultural, with some light industry. The code is considered a geographic number, meaning that the tariff for calls to this number is based on the distance from the caller's location, as per traditional PSTN regulations. However, with the widespread adoption of VoIP and mobile telephony, many residents and businesses may use alternative communication methods, but the fixed-line infrastructure remains operational.

Overlays and Number Portability

As of the latest available data, there are no overlay codes for the 5756 area. The Kharkiv region has multiple area codes for different towns, and 5756 is unique to Krasnokutsk. Subscribers in this area can participate in fixed-line number portability, allowing them to retain their number if they switch to a different fixed-line operator, provided the new operator serves the same geographic area. For callers, it is essential to always include the trunk prefix (0) when dialing domestically, even if the call is made from a mobile phone, as Ukrainian numbering regulations require the full national significant number (NSN) to be dialed.

Practical Tips for Callers

• Domestic calls: Dial 0 5756 followed by the local subscriber number.
• International calls: Dial your country's exit code, then 380 5756, followed by the local subscriber number.
• Mobile calls: Even when calling from a Ukrainian mobile phone, you must include the trunk prefix 0 before the area code.
• Emergency services: In Ukraine, emergency numbers (101, 102, 103, 104) are short codes and do not require the area code.
