Gauteng Area Codes
South Africa

This page connects Gauteng administrative geography with carefully qualified telephone-code associations. Telephone zones can cross administrative borders, so the two entities are not treated as identical.

Entity boundary

Region vs. Telephone Area

Telephone areas do not always follow provincial borders. Province pages and telephone-zone pages are separate entities, and a prefix alone does not prove a caller’s current physical location or carrier.

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

Directory scope
