Regulatory and Technical Notes
As a geographic number, the +380 4631 prefix is tied to the physical location of the fixed-line network. However, number portability allows subscribers to retain their numbers when switching between fixed-line operators within the same geographic area. Calls to these numbers are typically routed over the PSTN or VoIP networks, and tariff structures depend on the caller's operator and subscription plan. Since 2015, Ukraine has implemented a unified numbering plan, and all geographic numbers have a fixed length of nine digits after the country code, including the area code.
