Telephone numbers in Trellin are assigned by the Department of Telephonic Administration, an administrative office under the Ministry of Energy and Communications. Numbers have ten digits, the first three signifying the area code or the mobile network operator's code.
Structure
Trellin uses a ten-digit numbering plan, with the first three digits assigned to landlines and mobile numbers based on their area or mobile network operator's code. Until 1984, provinces were assigned an area code for the entire province, but most were subsequently divided as domestic phone ownership increased. In general, provinces with a population above five million were split into two or three subregions. For mobile network operators, the third digit is not reserved for the operator's code, an alteration introduced in 2005 amid soaring rates of mobile phone ownership.
