Geographic Overview
The +380 51 area code is the National Destination Code (NDC) for the Mykolayiv region of Ukraine, designated for fixed-line telephone services. This geographic code covers the administrative territory of Mykolayiv Oblast, including the city of Mykolayiv (also spelled Mykolaiv) and its surrounding districts. The region is a key industrial and maritime hub on the Southern Bug River, near the Black Sea. Subscribers within this area are assigned numbers in the format +380 51 XX XX XX, where the total subscriber number length is seven digits after the country code.
Dialing Formats
For local callers within Ukraine, the national trunk prefix '0' is used before the area code. Thus, to call a fixed line in Mykolayiv from another Ukrainian city, you would dial: 0 51 XXX XX XX. For international callers, the format is: +380 51 XXX XX XX (or 00380 51 XXX XX XX from countries using the international prefix 00). It is important to note that the leading '0' is dropped when dialing from abroad.
Geographic Coverage and Numbering
The +380 51 code is a geographic allocation, meaning that the number is tied to a physical location. The numbering plan follows the ITU-T E.164 recommendation, with the country code +380, followed by the NDC (51), and the subscriber number. The Mykolayiv region includes several cities and towns, such as Pervomaisk, Voznesensk, and Ochakiv, all of which fall under the same area code. There are no overlay codes currently in effect for this region, so the 51 code is the sole geographic code for the oblast.
Caller Instructions
When calling a Mykolayiv fixed line from abroad, always use the international format: +380 51 followed by the seven-digit local number. If you are within Ukraine but outside the Mykolayiv region, dial 0 51 and then the seven-digit number. For local calls within the same area code, you may need to dial the full national number (including the area code) depending on the current regulations; however, it is always safe to use the full national format. Ensure you have the correct country code and area code to avoid misdialing.
