Region vs. Telephone Area
Domestic long-distance and outbound international calls use a two-digit carrier selection code. The safest universal representation is the plus format. Mobile number portability means a prefix does not reliably identify the current operator.
A code listed beside a city reflects the featured numbering association; it does not assert that every community in Rio de Janeiro uses that code or that the code stops at the administrative border.
