Region vs. Telephone Area
The prefix +7 alone is not sufficient to identify a number as Russian. Russia also spans 11 time zones, so local time must be calculated for the specific city or region.
A code listed beside a city reflects the featured numbering association; it does not assert that every community in Rostov Oblast uses that code or that the code stops at the administrative border.
