Area Code 6138 – Kamyanets'-Dniprovs'ka, Zaporizhzhia

Overview of Area Code +380 6138

Area code 6138 is a geographic National Destination Code (NDC) within the Ukrainian national numbering plan, assigned to the town of Kamyanets'-Dniprovs'ka and its surrounding district in the Zaporizhzhia Oblast of southeastern Ukraine. The code is part of the broader 613 numbering area, which serves the southern part of Zaporizhzhia region. Kamyanets'-Dniprovs'ka is located on the left bank of the Dnipro River, near the Kakhovka Reservoir, and is an administrative center of the Kamianka-Dniprovskyi Raion.

Geographic Coverage and Administrative Jurisdiction

The 6138 prefix covers the urban-type settlement of Kamyanets'-Dniprovs'ka and the adjacent rural localities within the raion. This includes smaller villages and agricultural communities that rely on the fixed-line infrastructure of the regional telecom operator. The area is primarily residential and agricultural, with limited industrial activity. The code is administered by the Ukrainian State Service of Special Communication and Information Protection, in accordance with the national numbering plan based on ITU-T E.164 recommendations.

Dialing Formats and Instructions

For callers within Ukraine, the national trunk prefix is 0, followed by the area code and the subscriber number. The local subscriber number length for 6138 is typically 5 digits, making the complete national significant number (NSN) 9 digits long (excluding the trunk prefix). For example, a local number might be formatted as:

• National dialing (from another Ukrainian city): 0 6138 2-34-56
• International dialing (from abroad): +380 6138 2-34-56

When calling within the same area code, local callers may often omit the trunk prefix and area code, dialing only the 5-digit subscriber number. However, for clarity and to avoid misdialing, it is recommended to use the full national format.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for the 6138 area. The numbering capacity is sufficient for the population density of the region. However, due to the ongoing modernization of Ukraine's telecom networks, some fixed-line services may be migrated to VoIP or fiber-optic infrastructure, but the geographic number assignment remains unchanged. Subscriber numbers are portable within the same geographic area, but not across different NDCs.

Caller Instructions

For local callers within Kamyanets'-Dniprovs'ka, dial the subscriber number directly. For callers from other Ukrainian cities, dial 0 then 6138 then the subscriber number. For international callers, dial the international access code (e.g., 00 from most countries, or + from mobile), then 380 (Ukraine's country code), then 6138, then the subscriber number. Ensure you drop the trunk prefix 0 when calling from abroad.
