Introduction
The API checks the last time that the SIM card associated with a mobile number (MSISDN) changed. The response may be a timestamp or a yes/no for a defined period (e.g. last 24h).
Key Benefits
- Increased security without additional friction for the user.
- Reduces fraud costs.
- Builds customer confidence in digital journeys and improves customer retention.
- Helps fulfil regulatory requirements for ‘Strong Customer Authentication’ (SCA) under PSD2.
Use Cases
- Fraud prevention in banking: A bank may query the API when a transaction appears suspicious. The SIM swap information feeds into the bank risk decision engine and security measures are applied accordingly by the bank.
- Fraud prevention for password reset (various sectors): Password reset is often protected via a mobile verification e.g. SMS One Time Password. The online service provider may query the API to secure the mobile verification. A recent SIM swap may indicate a risk of account takeover fraud and the service provider can adapt the security measures accordingly.
