Fraudulent international phone calls represent a growing threat to French consumers. Whether via premium-rate numbers, foreign country code spoofing, offshore call centres, or investment scams organised from abroad, the techniques are multiplying and growing more sophisticated. This guide gives you the tools to identify, avoid and report fraudulent international calls.
The main categories of fraudulent international calls
- Wangiri (one-ring scam): a single-ring call from an exotic code, designed to make you call back a premium international service.
- Offshore canvassing centres: centres operating from low-wage countries (Morocco, Tunisia, Senegal, Moldova) canvass French consumers, sometimes displaying fake French caller IDs.
- Cross-border investment scams: fraudsters based abroad contact you to offer fraudulent financial products — crypto, forex, exotic equities. The AMF (amf-france.org) maintains a regularly updated blacklist.
- Spoofing of French institutions from abroad: fraudsters display your bank's or the CPAM's number while calling from a server on the other side of the world.
Why these scams are difficult to prosecute
The cross-border nature of these frauds significantly complicates prosecution. VoIP infrastructure is often hosted in countries without mutual legal assistance treaties with France. Servers change hosting providers frequently. This is why individual prevention and vigilance remain the most effective tools — international extradition and asset seizure procedures are long and uncertain.
Daily protection habits
- Never call back an unknown foreign number that hung up in under five seconds without first checking on TelCheck.
- Check your phone bill every month to detect charges linked to unwanted international calls.
- Enable outgoing international call restrictions on your line if you never call abroad — most French operators offer this option.
- Report suspicious international numbers on TelCheck to alert the community.
How to report a fraudulent international call
Report any fraudulent international call on TelCheck (to help the community), on Signal Conso (signalconso.gouv.fr) (to alert French authorities), and directly to ARCEP (arcep.fr) if you suspect an organised campaign. In case of financial harm, file a police complaint and call France Victimes on 116 006 (free, 7 days a week).
