Entity boundary

Region vs. Telephone Area

Indonesia spans three time zones, and a geographic code can cover more than its best-known city. Current carrier or precise location cannot be established from a prefix alone.

A code listed beside a city reflects the featured numbering association; it does not assert that every community in Central Java uses that code or that the code stops at the administrative border.

Directory scope

This launch includes 1 verified or clearly qualified code association for the featured cities in Central Java.
