Telephone numbers in Madagascar are seven digits long, the first two digits being an area code.
Recent ITU documents suggest the area code is preceded by a two digit operator code, for example "20" for Telecom Malagasy.

At national level, a closed numbering system of seven digits is used. That is, all subscriber numbers requested to the same operator Telecom Malagasy (local and national) can be obtained by dialling seven digits (ZPQMCDU).
