Belgian telecom operators intercepted over 103 million fraud calls in the first half of 2026. Spoofing in particular remains a major problem, despite stricter measures from the telecom sector and the government.
The Belgian Institute for Postal Services and Telecommunications (BIPT) works closely with Belgian telecom operators to curb telecom fraud. The most recent figures show that the sector is making significant progress, but criminals are continuously adapting their methods. The fight against fraud therefore remains an ongoing challenge.
The data shows that the telecom sector is increasingly capable of detecting and blocking fraudulent communication before it reaches consumers. Nevertheless, vigilance remains essential, especially as fraudsters explore new channels such as WhatsApp to continue their activities.
103 million calls
The report shows that in the first half of 2026, over 103 million fraudulent communications were intercepted. In more than 70 percent of these cases, it concerned spoofing, where criminals use a fake phone number to gain trust. In addition, over 7.2 million fraudulent SMS messages and 419 million fraudulent emails were blocked. Approximately 6,000 fraudulent mobile numbers were also deactivated and 53,000 numbers were blocked.
The BIPT points out that fraudsters are adapting their tactics. Although spoofing and smishing are less successful due to the measures taken, fraud is shifting to other channels such as WhatsApp, over which telecom operators have less control. The institute is currently investigating how this form of fraud can be countered. The messaging app is testing a new feature to warn you about potential scam messages.
Role of legislation and cooperation
The BIPT highlights the impact of the amended legislation that enables the blocking and deactivation of fraudulent numbers. In addition, the institute works closely with the financial sector, which can report suspicious numbers. After validation, the BIPT can request operators to block these numbers immediately.
Telecom operators are continuously investing in advanced detection systems and cooperation with authorities to detect new forms of fraud more quickly. Nevertheless, the BIPT emphasizes that consumers also play a crucial role in the fight against telecom fraud.
The BIPT warns against calls displayed as “private”, “anonymous”, or “unknown”. Although not all such calls are fraudulent, they should be considered suspicious. Consumers are advised not to answer such calls directly, but to send them to voicemail to evaluate messages calmly.
