As per the latest data reported by the service providers, by the end of September 2013 about 102.49 million subscribers have submitted their requests to different service providers for porting their mobile number (MNP requests).
 
In MNP Zone-I (Northern & Western India) maximum number of requests have been received in Rajasthan (about 10.15 million) followed by Gujarat(about 8.86 million) whereas in MNP Zone-II (Southern & Eastern) maximum number of requests have been received in Karnataka (about 11.84 million) followed by Andhra Pradesh Service area (about 9.30 million).
 
In the month of September 2013, total number of subscribers who have submitted their request for MNP is 2.29 million.

In September, Telecom Regulatory Authority of India (TRAI) proposed that telecom service providers will have six months time to implement full mobile number portability.
 
Full MNP allows a subscriber to retain his mobile telephone number when he moves from one Access Provider to another irrespective of the mobile technology or from one cellular mobile technology to another of the same Access Provider. Presently the facility of MNP is restricted to the licensed service area only.
