The Telecom Regulatory Authority of India (TRAI) has not recommended 11 digit mobile numbers and has stated that the country will continue following a 10-digit numbering for mobile services. Further, the TRAI has only suggested prefixing ‘0’ when mobile numbers are called from landlines.

As per the sector regulator, the change in the mobile number from 10 digits to 11 digits could lead to more dialing errors, infructuous traffic, and loss of revenue to the operator.

The introduction of a dialing prefix for a particular type of call is not akin to increasing the number of digits in the telephone number, TRAI said.

TRAI added that the recommendation on prefixing ‘0’ for calls from fixed line to mobile numbers will generate 2,544 million additional numbering resources for mobile services to cater to the future requirements. Additionally, TRAI has also recommended issuing of a revised and new National Numbering Plan (NNP) at the earliest, and has made suggestions on ways to free up unutilised capacities, to create space for mobiles services.

Recently, the Telecom Regulatory Authority of India (TRAI) released recommendations on ‘Ensuring adequate numbering resources for fixed line and mobile services suggesting that all data-only use SIM cards used for dongles etc. must shift from 10-digit numbering to 13-digit numbering allocated by Department of Telecommunications (DoT).
