Now, prefix ‘0’ before calling up any mobile number from a landline
Now onwards, while dialling a mobile number from a landline, you will have to prefix ‘0’. This rule came into effect from January 15 and is in line with a directive issued by the Department of Telecommunications (DoT).
Irrespective of the service provider, this rule applies to everyone in India.
The directive was issued last November. In case you fail to prefix ‘0’ before dialling a mobile number from your landline, the call won’t go through. Most telecom operators have started informing their customers about this change of rule. However, there won’t be any change in calls from landline to landline, mobile to landline, or mobile to mobile.
According to the DoT, the directive was issued to ensure “adequate numbering resources for fixed-line and mobile services”. It also directed telecom operators to apprise subscribers of the change in rule. “This announcement (dialling the prefix ‘0’) should be played whenever a subscriber dials a fixed to mobile call without prefixing ‘0’” read the order.
On its official Twitter handle, the DoT put up a tweet informing users of the rule. It stated: “Landline users will be required to add the prefix '0' before dialling a mobile number from January 15, 2021.”
Few days later, on November 25, 2020, the Ministry of Communications and Information Technology issued a circular, where it stated that the prefix ‘0’ rule will free up sufficient numbering resources for future use. The circular added, “A total of approximately 2,539 million numbering series is expected to be generated from the above.”
Telcos have started informing their fixed-line users that the new rule is now applicable. Earlier, a person had to prefix ‘0’ only while calling a mobile phone from a landline outside a service area.
