History
Algeria introduced an eight-digit national significant number for fixed and mobile subscribers in December 2000. In February 2008, ARPCE expanded mobile, value-added, VSAT and non-geographic VoIP formats to ten domestic digits. Geographic fixed-line numbers remained at nine domestic digits because of technical constraints in the fixed-network migration. The current ARPCE numbering overview preserves this distinction, while the regulator-published Algérie Télécom catalogue provides the detailed OAB-to-wilaya table used here.
The Algérie Télécom table lists both 21 and 23 for Algiers. This priority directory presents 21; code 23 is not claimed to be inactive.
