Harassing phone calls, fake mobile calls blocked from 19 November
This is the second step stipulated by the Agcom regulation after the fixed-network call stop on 19 August 2025
Key points
It is a long-awaited date for citizen-consumers, the constant target of wild telemarketing: Wednesday 19 November the block on fake domestic calls from mobile numbers will come into force. A step that follows that of last 19 August, when a first regulatory clampdown was triggered with the entry into force of a resolution of the Agcom (Communications Guarantee Authority) against teleselling and wild telemarketing activities, with which operators must block calls from abroad that use fake Italian landline numbers to deceive citizens.
Blocking to mobile numbers
Precisely on 19 November, the extension of the 'spoofing' block to mobile numbers will be triggered: operators and call centres will no longer be able to use fake Italian mobile numbers to trick users into answering and offering them commercial contracts or financial investments. This is an important test to see whether the new rules will be able to limit the 15 billion unwanted calls that, Codacons estimates, Italians receive on their phones every year.
What is 'spoofing'
The phenomenon consists of the manipulation of the information carrying the identity of the caller (the so-called CLI) in order to prevent its identification and recall (the user displays a number that does not correspond to who actually originated the call).
These are in fact all those calls that are received from a non-existent and unregistered telephone number, in order to prevent their identification, for the purposes of aggressive or illegal telemarketing or teleselling or, even worse, calls that conceal fraud perpetrated by using a telephone number modified so as to present itself to the user receiving them as a public (e.g. law enforcement agencies) or private (e.g. a bank) entity.
The blocking of telephone calls from abroad with fixed-network CLI (Calling Line Identification), Agcom had informed Agcom two months after the implementation of the authority regulation introduced in August, had resulted in the filtering of approximately 43 million calls: 1.3 million spoofing calls per day.
