In addition, the FTC requires a process similar to TPV for many orders and to have reliable documentation of their orders, and other transaction types. Third-party verification is now the de facto standard for transactions of all types where a legally binding authentication and confirmation are required, but a signed document is impractical or impossible. It is being applied in hospitals and else where in healthcare for records releases; in schools for parental program approvals; by local governments as notification of impending actions; by attorneys themselves for service authorizations; by service providers for work authorizations. In all cases, based upon Federal Rules and the U.S.Code, phone verifications are authorized and legally binding, assuming that the verification is recorded and available for audit for a minimum of 24 months, and that identity of the authorizing person can reasonably be verified, such as by a social security number, driver's license, date of birth or other unique identifiers.
