Overlay and Numbering Changes

As of the latest updates, there is no overlay code for this area.

It is advisable to check with the local telecom operator for any recent changes in dialing procedures.

Caller Instructions

• Local callers: If you are within the same area code (i.e., calling from another number in Dzerzhynsk), you can dial the subscriber number directly without the area code. For example, dial 123 45 67.
• National callers: When calling from other regions of Ukraine, always use the trunk prefix '0' followed by the area code and subscriber number: 0 4146 123 45 67.
• International callers: Use the full international format: +380 4146 123 45 67. This ensures proper routing through the international gateway.

Important Notes

This area code is strictly for fixed-line services. Mobile numbers in Ukraine have their own non-geographic codes (e.g., 50, 66, 95, etc.) and are not tied to a specific region. If you are trying to reach a mobile user in Dzerzhynsk, you would need to dial their mobile number with the appropriate mobile prefix. Also, be aware that number portability exists in Ukraine, allowing users to keep their numbers when switching operators, but for fixed lines, portability is limited.
