Systems and methods to verify and process requests received via social networking websites. In one aspect, a system includes a data storage facility to store data associated with a first phone number; and an interchange coupled with the data storage facility. The interchange includes a common format processor and a plurality of converters to interface with a plurality of controllers of mobile communications. The converters communicate with the controllers in different formats and with the common format processor in a common format. The common format processor receives a request from a first user via a social networking website, identifies a first phone number of the first user and a second phone number of a second user, based on the social networking website, and uses the converters to communicate with at least one of the mobile phones at the first and second phone numbers to confirm and/or approve the request.
