📍 Geographic Location of Yablanovo
Geographic Overview
The +359 4587 prefix is a geographic National Destination Code (NDC) assigned to the town of Yablanovo and its surrounding areas within Bulgaria. Yablanovo is a small settlement located in the central part of the country, administratively part of the Stara Zagora Province. This numbering area falls under the Bulgarian national numbering plan, which adheres to the ITU-T E.164 standard. The code is used for fixed-line (PSTN) services, connecting subscribers to the public switched telephone network.
Dialing Formats
When calling a number in Yablanovo from within Bulgaria, subscribers must dial the trunk prefix '0' followed by the area code and the local subscriber number. For example, a local number would be dialed as: 0 4587 XXX XXX. The total length of a national significant number (NSN) for Bulgarian fixed lines is typically 8 to 9 digits, including the leading '0' for domestic calls. For international callers, the country code +359 is used, followed by the area code without the leading '0'. Thus, an international call would be formatted as: +359 4587 XXX XXX.

Caller Instructions
For local callers within Yablanovo, it is possible to dial only the subscriber number for calls within the same exchange, but for clarity and to avoid misdialing, it is recommended to always use the full national format. For callers from other Bulgarian regions, dial '0' followed by '4587' and the subscriber number. For international callers, replace the leading '0' with +359. Ensure you have the correct country code and omit any leading zeros when dialing from abroad.
