Area Code 3628 – Miladinovo

Overview of Area Code 3628 in Bulgaria

Area code 3628 is a geographic National Destination Code (NDC) within the Bulgarian national numbering plan, conforming to ITU-T E.164 standards. It is assigned to the town of Miladinovo and its immediate surrounding areas. Miladinovo is a small settlement located in the Yambol Province of southeastern Bulgaria. The code is administered by the Communications Regulation Commission (CRC) of Bulgaria and is used exclusively for fixed-line (PSTN) services.

Geographic Coverage and Administrative Jurisdiction

The 3628 area code covers Miladinovo and the adjacent localities within the municipality of Tundzha, which falls under the administrative jurisdiction of the Yambol Province. This region is primarily rural, with agriculture being the dominant economic activity. The code serves residential subscribers, local businesses, and public institutions within this defined geographic area. As a geographic code, it is tied to the physical location of the subscriber's line, and calls to this code are routed to the local exchange serving Miladinovo.

Dialing Formats and Caller Instructions

For callers within Bulgaria, the national trunk prefix 0 is used before the area code. The full national dialing format is 0 3628 XXX XXX, where X represents the subscriber's local number. For example, a local number might be dialed as 03628 12345 from a Bulgarian fixed or mobile line. When calling from abroad, the international access prefix (typically 00 or +) is used, followed by Bulgaria's country code +359, the area code without the leading zero, and the subscriber number. Thus, an international caller would dial +359 3628 12345.

Overlay Considerations and Numbering

As of the latest CRC updates, there is no overlay code for the 3628 area. Subscribers in Miladinovo have a uniform number length of 8 digits when including the area code (0-3628-XXXX). The numbering capacity is sufficient for the low population density of the area, and no changes are anticipated in the near future. Local calls within the same area code can be made using only the subscriber number, but for clarity and to avoid confusion, it is recommended to use the full national format.

Practical Guidance for Callers

For local callers within Miladinovo, dialing the 5-digit subscriber number directly may work, but it is safer to use the full national format. For callers from other Bulgarian regions, always include the trunk prefix and area code. For international callers, ensure you replace the leading zero with the country code. Mobile and VoIP users should note that calls to geographic numbers are typically charged at standard fixed-line rates, which may vary depending on the operator and subscription plan. Emergency services (112) and directory inquiries (1180) are accessible without the area code.
