Area Code 37 – Chernivtsi

Geographic Coverage and Administrative Jurisdiction

The +380 37 country-code prefix is the national destination code (NDC) for the Chernivtsi Oblast of Ukraine, a region located in the southwestern part of the country, bordering Romania and Moldova. This geographic area code is assigned to fixed-line telephone services within the oblast, covering the administrative center of Chernivtsi city as well as the surrounding districts and towns, including Storozhynets, Kitsman, Zastavna, and Novoselytsia. The region is served by a mix of incumbent operators and alternative fixed-line providers, all of which route calls through the Ukrainian PSTN using the E.164 numbering plan.

Dialing Formats and Number Structure

When dialing a fixed-line number in the Chernivtsi region from within Ukraine, callers must use the trunk prefix '0' followed by the area code '37' and the subscriber number. The complete national significant number (NSN) for Chernivtsi numbers is nine digits in length, comprising the area code '37' and a seven-digit local subscriber number. For example, a local number might be formatted as 0 37 2 123-456. From abroad, callers must dial the international access prefix (00 or +), then the country code '380', followed by the area code '37' and the subscriber number, omitting the leading '0'. Thus, the same number would be dialed as +380 37 2 123-456.

Overlays and Numbering Changes

As of the latest ITU-T and Ukrainian national numbering plan updates, the Chernivtsi region does not have an overlay code. The area code '37' is exclusively assigned to geographic fixed-line services in this oblast. However, due to the ongoing modernization of Ukraine's telecommunications infrastructure, some fixed-line numbers may be migrated to VoIP or IP-based platforms, but they retain the geographic NDC for regulatory and emergency service routing purposes. Callers should always verify the current dialing procedures with their service provider, especially when calling from mobile networks, as some operators may require the national trunk prefix even for local calls.

Caller Instructions

For local callers within the Chernivtsi region, dialing a number in the same area code may require only the seven-digit subscriber number, depending on the operator's local dialing plan. However, for calls from other regions of Ukraine, the full national format (0 37 ...) is mandatory. International callers must use the plus sign (+) or their country's international exit code, followed by 380 and the area code without the leading zero. It is important to note that calls to Chernivtsi fixed lines are charged at national geographic rates, which are typically lower than mobile rates. For emergency services, callers should dial 101 (fire), 102 (police), or 103 (ambulance) regardless of the area code.
