Overlay and Numbering Considerations
As of the latest ITU-T E.164 national numbering plan for Ukraine, there is no overlay code for the Ruzhin area. The 4138 code is exclusively geographic and does not serve mobile or non-geographic services. Subscriber numbers are fixed and not portable to other geographic areas, though number portability exists for mobile services. The Ukrainian regulator, the Ukrainian State Centre of Radio Frequencies (UCRF), manages the allocation of such codes.
For businesses and residents in Ruzhin, this geographic code provides a local presence and is essential for routing calls within the PSTN. When dialing from abroad, ensure you have the correct international access code (e.g., 00 from most European countries, or 011 from North America) before the country code.
