Area Code 4850 – Teplodar, Odesa

Geographic Overview

The Ukrainian national destination code 4850 is a geographic area code assigned to the city of Teplodar, located in the Odesa Oblast of southern Ukraine. Teplodar is a small, planned city situated approximately 30 kilometers northeast of Odesa, the region's administrative and economic hub. The code 4850 is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the framework of ITU-T E.164. It is used for fixed-line PSTN services within the city limits and its immediate administrative territory.

Dialing Formats

For callers within Ukraine, the local dialing format requires the trunk prefix 0 followed by the area code and the subscriber number. Thus, a typical Teplodar fixed-line number is dialed as 0 4850 XX XX XX (where X represents the local 6-digit subscriber number). For international callers, the Ukrainian country code +380 replaces the trunk prefix, resulting in the format +380 4850 XX XX XX. When dialing from abroad, the leading zero is omitted. For example, a complete international number might appear as +380 4850 123 456. Within Teplodar, local calls may be possible using only the 6-digit subscriber number, depending on the operator's network configuration, but using the full national format is always safe.

Geographic Coverage and Administration

The 4850 code is exclusively allocated to Teplodar, which is a city of regional significance. It does not cover the larger Odesa metropolitan area, which uses the separate code 482 for its central districts. Teplodar's numbering capacity is managed by the Odesa branch of Ukrtelecom, the incumbent fixed-line operator, though alternative operators may also provide services under this code. As of the latest numbering plan updates, there are no overlay codes for Teplodar; the 4850 code serves the entire city and its adjacent settlements. The subscriber number length is 6 digits, making the total national significant number (NSN) length 9 digits (excluding the trunk prefix), consistent with the Ukrainian standard.

Caller Instructions

Local callers within Teplodar should dial the 6-digit subscriber number if supported, or the full national format 0 4850 XX XX XX for reliability. Callers from other Ukrainian cities must always use the national trunk prefix: 0 4850 XX XX XX. International callers should use their country's international exit code (e.g., 00 from most European countries, 011 from the US/Canada) followed by 380 4850 XX XX XX. No additional prefixes are required. It is important to note that while some VoIP services may allow direct IP-based dialing, traditional PSTN calls follow these standard routing rules.

Practical Considerations

Teplodar's numbering range is relatively small due to the city's modest population (approximately 10,000 inhabitants). However, the code remains fully operational and is used by residential and business subscribers alike. As with all Ukrainian geographic codes, number portability exists within the country, meaning a subscriber may retain their 4850 number even if they switch to a different fixed-line operator, as long as they remain within the same geographic area. For businesses, having a Teplodar number reinforces local presence and can be more cost-effective for customers calling from the region.
