Registration, verification and notification system

A non-transitory computer-readable storage medium containing instructions that, when executed by a processor, cause the processor to perform a method of verification and notification, the method comprising:

• receiving, from a user, information via a computing interface presented to the user as a result of an attempt by the user to access a service, the received information including a telephone number associated with the user;
• verifying the telephone number by:
• establishing a telephonic connection with the user using the received telephone number;
• communicating a verification code to the user through the telephonic connection;
• receiving, via the computing interface, a submitted verification code that is entered by the user;
• and
• verifying the telephone number if the submitted verification code is the same as the communicated verification code;
• completing a registration of the user based on the received information and verified telephone number, wherein the completed registration enables the user to access the service;
• maintaining a record of one or more notification events associated with actions that require acknowledgement by the user;
• upon receiving an indication of an occurrence of an established notification event, transmitting a message addressed to the verified telephone number indicating the occurrence of the notification event;
• and
• receiving, from the user, an acknowledgement of an action associated with the established notification event.
