You answered a call and something felt wrong. The caller was too insistent, knew surprising personal details, put you under pressure, or hung up abruptly when you asked a question. You may have shared no sensitive information — or you may have done so without immediately realising it. Either way, your actions in the next few minutes are critical.
Step 1: stay calm and note down the details
Immediately write down everything you can remember: the displayed number, time of the call, the name given, the organisation claimed, what was asked, and what — if anything — you shared. These details will be valuable if you need to file a complaint or contact your bank.
Step 2: check the number on TelCheck
Enter the calling number in TelCheck (telcheck.fr). Within seconds you will get a reputation score, the number's category, and comments from other users who received the same call. If dozens of users have already flagged it as a "fake bank adviser" or "CPF scam", this confirms you likely dealt with organised fraud.
Step 3: assess what you shared
- You gave an SMS code received during the call: contact your bank immediately, 24/7. That code likely authorised a transaction. Request an emergency block.
- You gave banking details (card number, IBAN): call your bank to cancel your card and monitor for unusual debits.
- You gave CPF or Mon Compte Formation credentials: log in immediately at moncompteformation.gouv.fr, change your password and check your training history.
- You gave personal data (name, address, national insurance number): report to the CNIL (cnil.fr) and monitor for unexpected post or emails in coming weeks.
- You installed software at the caller's request: disconnect the device from the internet immediately, change all passwords from a different device, and visit cybermalveillance.gouv.fr for specialist support.
Step 4: report the number and the incident
Even if you suffered no direct harm, report the number on TelCheck (telcheck.fr) to warn other users. Also report the incident on Signal Conso (signalconso.gouv.fr).
Step 5: file a complaint if you suffered harm
- Online at service-public.fr.
- At your nearest police station or gendarmerie.
- With your bank, which has a legal obligation to process unauthorised-transaction refund requests.
- Call France Victimes on 116 006 (free, 7 days a week) for support through the process.
Step 6: protect yourself going forward
Register on Bloctel (bloctel.gouv.fr) to reduce unsolicited commercial calls. Enable two-factor authentication on all sensitive accounts. Be wary of follow-up contacts — scammers sometimes sell lists of "active" numbers to other fraudsters.
