Why is a mobile number required?
Halocard requires a valid phone number to:
- Send SMS codes (known as "3D-Secure verification codes") to approve some online purchases. Please note these code are sent at the request of the merchant (not Halocard) in order to minimize fraud.
- To recover your account in the event suspicious activity is detected and/or your account has become compromised.
Disposable and burner numbers are not recommended and are used at your own risk.
