Date: 27 November 2020 Tags: IT, Mobile & Computers

Issue

The department of telecommunications (DoT) has made it mandatory to prefix 0 for all calls made from fixed lines to mobiles, effective 15 January.

 

Background

The Telecom Regulatory Authority of India’s (TRAI) had in May recommended a '0' prefix for all such calls to create sufficient numbering space for telecom service providers.

 

Details

  • Dialling “0” mobile phone numbers was a practice followed by outstation callers. This was avoided after government allowed inter-circle mobile number portability.

  • India has 10 digits mobile numbering plan with “0” and “1” reserved for special purposes. This means that effectively 800 crore combination of mobile numbers are possible.

  • The numbers in “9” series have all been used. To distinguish these mobile numbers from certain landline numbers having 10 digits code, prefixing has been made compulsory.

  • TRAI has also recommended that all 10 digit numbering code to be shifted to 13 digit code for M2M communication.

  • The decision to add prefix will not only clear the overlap between landline and mobile number carrying the same series but also free up numbering resources for mobile phones in future.

 

TRAI
