Fight against spam in Ukraine
Since October 2, 2025, mobile operators in Ukraine have blocked nearly 60 thousand numbers from which unsolicited advertising calls were made. In the first three months of this mechanism's operation, 59,071 numbers were blocked, indicating its effectiveness in combating spam.
Criteria for blocking spam numbers
The blocking of spam numbers became possible due to new criteria used for call checks. Among the main blocking criteria are:
- calls without communication;
- average call duration of less than 60 seconds;
- more than 50% of calls to different numbers;
- impossibility to call back;
- playback of a recorded message.
This allows for the detection and blocking of numbers used for sending spam.
“Since October 2, mobile operators are required to block spam numbers – and this mechanism has already demonstrated its effectiveness.”
Mikhailo Fedorov, Minister of Digital Transformation of Ukraine
In addition, there are possible ways to report spammers, such as contacting the mobile operator, submitting a complaint on the NCEC website, or calling the government's 'hotline' at 1545.
The implementation of new technologies, particularly 5G, also plays an important role in this process. The main advantage of 5G technology is a data transmission speed of about 500 Mbps per subscriber. Lviv became the first city in Ukraine where this technology was launched, which can help further combat spam and improve communication quality for users.
With the blocking of spam numbers and the introduction of new technologies like 5G, Ukraine is taking steps to improve the quality of communication and protect its citizens from intrusive advertising. This not only enhances the convenience of using mobile services but also creates a safer information environment. Continuing monitoring and improving spam protection mechanisms remain a priority for regulators and mobile operators in the future.
