NSN length 9 International call prefix 00 | Country calling code +244 Trunk prefix none | |
Telephone numbers in Angola are 9 digits long (except for special 1xx service numbers like Police and Emergency services), and must always be dialed in their entirety. Land-line (fixed-line) numbers start with digit 2, followed by 1 or 2 digits area code that corresponds to a geographic area. After the area code, there is the telecoms operator identifier, which consists of 1 digit, then the subscriber number. Mobile numbers have no geographic area, and they start with the operators identifier which currently are 91 and 92. (needs updating)
