M2M devices will have a 13-digit mobile number; here is why


Nov 11, 2011
Under this latest development, the existing mobile users’ numbers will be ported to 13-digits starting from October 1, 2018. The last date to complete the process would be December 31, 2018. “It is decided that 13-digit M2M (Machine-to-machine) numbering plan will be implemented from July 1, 2018. From this date onwards, all new M2M mobile connections will be allocated 13-digit numbers only… Migration of existing 10-digit M2M numbers will start latest by 1 October 2018 and shall be completed by 31 December 2018,” the official was quoted saying in the report.

If the decision is implemented, India will become the country with the longest mobile numbers, with China the only country at scale with 11 digit mobile numbers, not counting the area code. Apart from this, only French ‘regions’ of Gaudeloupe, Martinique and Reunion have longer numbers.

Meanwhile, the Ministry of Communication in a letter written to TRAI has reportedly said that ’13-digit numbering scheme has been approved for SIM-based M2M devices’. A M2M sim is actually the technology which enables devices and sensors or things to communicate with each other and with other Internet-enabled devices and systems. These sims can be used in any mobile phone.

The problem, however, with a 13-digit number is that it would be virtually impossible for a person to remember it, possibly leading to massive dislocations across business processes like banks where provisioning has been made to capture only 10 digit mobile numbers.

if we group numbers into groups of 3/4/5 digits we can easily remember them.

example: See this 13 digit number +91 9898882213875

in 3 digit grouping: +91 989 888 221 3875
in 4 digit grouping: +91 9898 8822 13875
in 5 digit grouping: +91 98988 82213 875
in 4+5 digit grouping: +91 9898 88221 3875

seems the normal users will not be affected; but still a possibility in distant future considering our sheer population.
The move, contrary to speculations doing rounds right now on social media, will not affect phone users. It is meant only for the SIM cards that are used in machines, such as internet-connected appliances.

Enough confusion. No 13 digit number for normal population. Period.

Already we have enough 10 digit series which we can't be replenished until the next 100 years.

We have

9xxxx Series , 8xxxx Series, 7xxxx Series with lots of unused numbers which will be again put in use.

From past few months 6xxxx series also is being supplied.

- We have 15% of subscribers not using their present numbers according to recent VLR data
- Aadhar linking will weed out more 10% connections which could be non genuine.
- Operators like Tata docomo, Aircel shutting down or Voda-Idea merging some 4-5 crore people will stop using same network cuz they will have dual SIM's.

Right now the genuine users come around 96 crores (0.96 Billion), out of the 120 crore (1.20 Billion) TRAI's number. https://gadgets.ndtv.com/telecom/news/indian-telecom-subscriber-base-dips-to-120-crores-in-october-trai-1787101

9XXXXXXXXX series alone has 9 billion numbers. India's population = 1.30 billion!

So Don't panic!
