The present invention provides methods and devices for determining the location, identity and age of a user who desires to initiate a gaming session from an uncontrolled environment such as a home, a gaming kiosk or a hotel room. In some implementations, the user's location is determined in part by reference to a database of land telephone lines and corresponding addresses. The location may be verified by other methods, e.g., by determining the location of an Internet service provider's network device that is near a user's host device or via a cellular telephone network. The user may be asked to input a confirmation number and/or make an oral response during a telephone call to a telephone number associated with the uncontrolled environment. The user may also be prompted to make statements verifying his or her identity, age, a maximum amount available for wagering or other statements.
