It 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.

Overlay and Numbering Changes

As of the latest available data, there is no overlay code for 6457. The region uses a closed numbering plan, meaning that local calls within the same area code do not require the trunk prefix or area code. However, due to the volatile situation in the region, some numbers may have been reassigned or may not be reachable. It is always advisable to verify the current status with your telecom provider.

Caller Instructions

For local callers within the 6457 area: simply dial the subscriber number without any prefix. For callers from other regions of Ukraine, dial the trunk prefix 0, then the area code 6457, followed by the subscriber number. For international callers, replace the trunk prefix with the country code +380 and omit the leading zero of the area code. Be aware that international call charges may apply, and some service providers may require additional dialing prefixes depending on the country of origin.

Given the geopolitical circumstances, it is recommended to use alternative communication methods if traditional PSTN lines are unavailable. VoIP services may route calls to these numbers, but the actual termination may depend on the network infrastructure.
