Area Code 3116 – Krumovo, Plovdiv

Overview of Area Code 3116 (Krumovo, Plovdiv)

Area code 3116 is a geographic National Destination Code (NDC) assigned to the town of Krumovo and its immediate vicinity, located within the Plovdiv Province of Bulgaria. Administratively, Krumovo is part of the Rodopi Municipality and lies approximately 10 kilometers southeast of the city of Plovdiv, the second-largest city in Bulgaria. The code is used for fixed-line (PSTN) services within this specific locality, following the Bulgarian numbering plan regulated by the Communications Regulation Commission (CRC) under the framework of ITU-T E.164.

Geographic Coverage and Dialing Formats

The 3116 area code covers Krumovo and the surrounding rural areas, including nearby villages such as Ustina and Tsalapitsa (though some may have their own codes). Subscriber numbers within this code typically consist of 5 to 6 digits, resulting in a total national significant number (NSN) length of 8 to 9 digits when combined with the trunk prefix and area code. For local calls within the same area code, callers in Bulgaria may dial only the subscriber number without the area code, depending on the operator's local dialing rules. However, for calls from other fixed or mobile networks within Bulgaria, the format is: 0 3116 XXX XXX (where X represents the subscriber digits). For international callers, the Bulgarian country code (+359) replaces the leading zero, so the international format becomes: +359 3116 XXX XXX.

Caller Instructions

For local callers (within Bulgaria): When dialing from a different geographic area or from a mobile phone, you must include the trunk prefix '0' followed by the area code 3116. For example, to call a landline in Krumovo from Sofia, dial: 0 3116 12345. For international callers: Dial your country's international access code (e.g., 00 from most European countries, 011 from the US/Canada), then Bulgaria's country code 359, followed by the area code without the leading zero, and the subscriber number. Example from the US: 011 359 3116 12345. From a mobile phone, you can typically use the '+' sign: +359 3116 12345.

Overlay and Numbering Considerations

As of the latest CRC updates, there is no overlay code for 3116; the code is dedicated solely to the Krumovo area. However, number portability is available in Bulgaria, allowing fixed-line subscribers to retain their numbers when changing operators within the same geographic area. This means that a number with the 3116 prefix may be served by any licensed fixed-line operator, not only the incumbent. When calling, the cost is determined by the caller's operator and the destination's type (geographic fixed line). Calls to 3116 numbers are typically charged at standard national fixed-line rates, and they are not considered premium or special tariff numbers.
