"Import of mobile handsets without International Mobile Equipment Identify (IMEI) number or with all-zero IMEI is prohibited with immediate effect," the Director General of Foreign Trade said in a notification.

IMEI - a unique 15-digit number - helps authorities trace the handset that has been used to make a call.

The Department of Telecom (DoT) had earlier directed telephone operators to disconnect services to subscribers who own handsets that do not have the IMEI code as such phones posed a security threat.

However, since then, the Cellular Operators Association of India has developed a software for embedding genuine identity code - issued by the global association of telecom operators - on handsets without the requisite IMEI numbers.
