A system and method for enabling out of band biometric verification is disclosed. The system includes a biometric engine coupled with an interactive messaging system and configured as an identity provider. The biometric identity provider includes a biometric enrollment process using open standard authentication protocols. The identity provider may answer calls generated by a service provider for biometric verification request for a user by sending an interactive message to a wireless mobile device associated to the user. The user captures and sends a biometric input to the identity provider. Biometrics provided by a user are compared by the biometric engine against biometric templates stored for that user in order to verify the user. The identity provider then sends a response back to the service provider. The service provider may grant or deny services to a user depending on the response.
