Abstract: A system and method are described for verifying a user. More specifically, a user contacts a goods or service provider and gives that provider information about himself or herself in order to register for receipt of goods or services. The provider then uses this information along with other information detected from another source, such as a network provider, to verify that the user is providing accurate information. Once the provider has determined that the information provided by the user is accurate, the user is allowed to register for certain services or purchase goods. A component of these systems and methods is to perform format and frequency of usage checks on the received data from the user and/or the network provider.
