📍 Geographic Location of Novo Zhelezare
Geographic Overview
The +359 3177 prefix is a geographic National Destination Code (NDC) assigned to the town of Novo Zhelezare and its surrounding areas within the Plovdiv Province of Bulgaria. This code is part of the Bulgarian PSTN numbering plan, which follows ITU-T E.164 standards. The administrative jurisdiction falls under the Plovdiv Municipality, and the area is served by fixed-line operators, including the incumbent Bulgarian Telecommunications Company (BTC) and alternative carriers that have implemented local loop unbundling.
Dialing Formats
When calling a landline in Novo Zhelezare from within Bulgaria, subscribers must dial the trunk prefix 0 followed by the area code 3177 and the subscriber number. The national significant number (NSN) is 8 digits long, comprising the NDC and a 4-digit local subscriber number. For example, a local number such as 1234 would be dialed as 03177 1234 from anywhere in the country.
For international callers, the Bulgarian country code +359 replaces the trunk prefix, and the leading 0 is omitted. Thus, the same number would be dialed as +359 3177 1234. It is essential to note that the area code is an integral part of the number and cannot be omitted, even for on-net calls within the same exchange.
Coverage and Localities
The 3177 area code covers Novo Zhelezare and may also serve adjacent hamlets and rural zones within the Plovdiv Province. The region is primarily agricultural, with a low population density, and the subscriber base is relatively small. This means that the number range is not fully exhausted, and new allocations are rare.
Overlay and Numbering Considerations
Currently, there is no overlay code for the 3177 area. Bulgaria's numbering plan is closed, and the National Regulatory Authority (CRC) manages the allocation of NDCs. As of the latest updates, no changes are anticipated for this geographic area code. However, subscribers should be aware that number portability is available for fixed-line services, allowing users to retain their numbers when switching operators, though the geographic significance of the prefix remains unchanged.
Caller Instructions
For local callers within Novo Zhelezare, the full national format (including the area code) is always required. For callers from other Bulgarian regions, dialing 0 before the area code is mandatory. International callers must use the +359 country code and drop the leading zero. Always verify the subscriber number length, as it is fixed at 4 digits after the area code.
