Area Code 3855 – Krasilov, Khmelnytskyi

Geographic Overview

The +380 3855 prefix is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network of Krasyliv, a city in the Khmelnytskyi Oblast of western Ukraine. This code 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 serves the city of Krasyliv and the surrounding rural settlements within the Krasyliv Raion. As a geographic code, it is tied to a specific administrative territory, and calls to this prefix are routed via the public switched telephone network (PSTN) to local exchanges.

Dialing Formats

For callers within Ukraine, the national trunk prefix is 0, so a local call to a Krasyliv number requires dialing 0 3855 XXX XXX (where X represents the subscriber number). For international callers, the country code for Ukraine is +380, so the full international format is +380 3855 XXX XXX. When dialing from abroad, the leading zero of the NDC is omitted. For example, a typical Krasyliv landline number might be dialed as +380 3855 12345 from outside Ukraine, or 03855 12345 from a Ukrainian mobile or fixed line.

Caller Instructions

Local callers within Krasyliv may sometimes use abbreviated dialing for numbers within the same exchange, but for clarity and consistency, the full national format is recommended. Mobile callers in Ukraine should always use the national format (0 3855 ...) even when dialing from within the same area, as mobile networks do not recognize local abbreviated dialing. Foreign callers should replace the trunk prefix 0 with the +380 country code. It is important to note that when traveling in Ukraine, international callers should use the local access code (00) or the plus sign (+) followed by the country code, depending on the phone system.

Regulatory and Technical Notes

As a fixed-line prefix, numbers under 3855 are primarily used by residential and business subscribers connected to the local PSTN. In recent years, some fixed-line operators have migrated to VoIP backbones, but the geographic significance of the prefix remains for number portability and emergency services routing. The Ukrainian numbering plan follows the closed dialing plan for fixed lines, meaning that the full national number (including the trunk prefix) must be dialed for all calls, except for emergency numbers. The code 3855 is not an overlay; it is the sole geographic code for the Krasyliv area. For any changes in numbering or operator assignments, consult the National Commission for State Regulation of Communications and Informatization (NCCIR).
