DoT has amended the National Numbering Plan 2003 for migration from the existing 10-digit mobile numbering plan to an 11-digit numbering plan by prefixing “9” to the two-digit PLMN Access Code. The proposed migration is likely to be implemented from January 1, 2010. The current numbering plan was formulated in 2003 on a forecast of 50 per cent teledensity by 2030, allowing for 750 million telephone connections (fixed and mobile). With the country adding 10-14 million mobile subscribers each month, the wireless subscriber base has already crossed 500 million a year ahead of the target.
