A vishing call cannot be handled through a single reporting button. The right channel depends on what actually happened: a suspicious call, an associated SMS, a fake website, data disclosed, a bank debit or an immediate threat. In 2026, official French channels exist, but they do not serve the same purpose.
The right reflex can be summarized in three steps: secure, preserve evidence, report. Secure the victim or exposed account first, keep evidence, then choose the reporting route according to the channel and the loss.
The simple rule: secure, preserve evidence, report
Before choosing a platform, classify the incident with three questions: is there immediate danger, was there loss or compromise, and which channel carried the attack? This is consistent with Service-Public guidance on phishing and vishing.
1. First reduce the operational risk
If the victim disclosed a code, password, bank detail or internal information, the first move is to reduce damage: block or dispute payments, change affected access, alert IT in a professional context and record the evidence.
2. 33700: the right channel for SMS, unwanted calls and voice spam
33700 is the French platform against unwanted SMS and calls. Service-Public states that reports can be made through 33 700, an online form or screenshots. It is not a complaint, a banking assistance service or a promise of immediate blocking.
3. PHAROS: only when public illegal online content is involved
The Service-Public page on illegal online content states that PHAROS is used to report content published on the Internet when it is accessible to web users and falls within specific illegal categories. A simple phone call usually belongs to 33700, the operator, the bank, 17Cyber or a complaint depending on severity.
4. 17Cyber: assistance when the victim needs guidance
17Cyber is presented as a public online assistance service for victims of cyber malicious activity. It helps diagnose and orient, but does not replace bank blocking, telecom reporting or a complaint.
5. The operator: essential when the line or number is involved
The telecom operator should be contacted when the incident affects the line itself: suspected spoofing, SIM swap, repeated calls, premium-rate number, blocking requirement or technical traces. Structured monitoring through HUHU real-time alerts helps teams spot reputation issues earlier.
Recommended alert order by scenario
| Situation | First action | Additional report |
|---|---|---|
| Suspicious call without data disclosed | Do not call back, keep number and time | 33700 if unwanted or fraudulent call |
| Bank code or password disclosed | Bank or affected service, change access | 17Cyber for guidance, complaint if loss occurred |
| Public fake website used in the scam | Keep URL and screenshots | Website reporting, PHAROS only if the content fits its scope |
What evidence should be kept before reporting?
Keep the displayed number, date, time, call duration, associated SMS messages, links, screenshots, scam script and actions already taken. HUHU has a dedicated guide on evidence to keep after a fraudulent call.
The case of call centers and support teams
The playbook should separate four queues: victim assistance, telecom signal, web content and brand reputation. This complements our guide to 33700 and voice spam.
