With the increasing mobile telephones, DOT is trying to rearrange the number system for telephones. Considering the fact that landlines and CDMA lines are mostly on the decline, it is proposing to utilise these numbers for mobile phones. Accordingly landlines numbers will be restricted to numbers starting with 2 and 4. Series starting with 92 and 93, which are mainly for the CDMA numbers, will also be allotted to GSM telephones.
However, the proposal of the TRAI to allot ten digit numbers to landlines has not been accepted by the DOT.
