Suspicious calls from a 04 number: what to do?
Receiving a call from an unknown 04 number does not necessarily mean it is dangerous — but it pays to stay vigilant. Best practices: do not call back an unknown number without identifying it first. Never share personal information, banking details, or passwords over the phone, regardless of what the caller claims. If the call seems suspicious (pressure tactics, urgency, requests for money, identity impersonation), hang up immediately. Report the number on TelCheck to help the community. If you have been a victim of fraud, file a report online at cybermalveillance.gouv.fr or directly with law enforcement.
