History
The Fundamental Technical Plan National 2000 established the base numbering framework, with later ministerial amendments updating geographic and service allocations. Outbound international carrier-selection prefixes vary, so the plus sign is the safest universal format.
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.
