Each zone is allowed to have multiple private operators (earlier it was 2 private +BSNL/MTNL, subsequently it was changed to 3 private + BSNL/MTNL in GSM 900/1800, now each zone has 4-5 operators including BSNL/MTNL in GSM, and 2 private + BSNL/MTNL in CDMA). All mobile phone numbers are 10 digits long, split up as OO-AA-NNNNNN where OO is the operator code, AA is the zone Code assigned to the operator, and NNNNNN is the subscriber number. Recently, some operators have been allotted "OOAA" series beginning "8".The same have begun to roll out.
