First digit 7 was reserved at first exclusively for radiophone use (iDEN technology), but soaring demand for new mobile numbers eventually forced unnumber ranges starting with 7 to be released for general mobile use.Historically, the higher ranges of the 9 initial digit ( 96-99 ) were originally assigned to the old state monopolies before the privatization of Brazil's telephony system, and later to their privatized direct successors. In order to create a competitive market, later the Brazilian government auctioned further mobile service licenses, filling the available number ranges backwards - first with the lower ranges of 9 (91-95) , then 8 , and so on.[5] As a consequence, in the beginning 9 was more commonly assigned to mobile operators that older technologies such as AMPS (analog), TDMA and CDMA, while for some time 8 was specifically reserved for all new GSM licenses. Now GSM is almost universally adopted by Brazilian mobile operators and this distinction is no longer meaningful. Mobile phone numbers always have eight or nine digits now, but seven digits were usual in the first years. The last area code to convert fully to eight digits was 61 (comprising the national capital, Brasília, and neighbouring areas), in 2005.
