India Cellphone Numbering

All mobile numbers in India have the prefix 9 (This includes pager services,

but the use of pagers is on the decline). Each zone is allowed to have multiple

private operators (earlier it was 2 private + BSNL, subsequently it was changed

to 3 private + BSNL in GSM 900/1800, now it also includes 2 private

+ BSNL in CDMA). All cellphone numbers are 10 digits long, (normally)

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.
