In 2026, number spoofing allows fraudsters to display an official bank or utility caller ID on your screen. At the same time, perfectly legitimate companies sometimes call from unknown numbers. Identifying a trustworthy professional call requires a structured verification process.
A step-by-step verification process
- 1. Check the number on TelCheck. Community reputation scores and caller comments reveal within seconds whether the number is linked to aggressive canvassing or a known scam.
- 2. Verify the company's legal existence on Societe.com or Infogreffe.fr. A company absent from the French commercial register is a major red flag.
- 3. Find the official number and call back yourself. Never redial the number that called you. Find the company's official contact on its website or at service-public.fr.
- 4. Check sector-specific registers: financial advisers on ORIAS (orias.fr), investment firms on the AMF (amf-france.org), banks and insurers on the ACPR (acpr.banque-france.fr).
Red flags and your rights
Artificial time pressure, refusal to provide a callback number, requests for immediate payment, and demands for personal codes are all clear warning signs. Register on Bloctel (bloctel.gouv.fr) and report abusive numbers to the DGCCRF via Signal Conso (signalconso.gouv.fr).
