Systems and methods disclosed herein provide a geo-targeted online reservation system that ensures authenticity of customer devices requesting reservations by generating reservations only if threshold authentication conditions are satisfied. For example, a computing device registered with a server system receives inputs for requesting a reservation of a limited release product and for configuring the product. To authenticate the computing device, the server device transmits an electronic message to the computing device requesting the computing device to respond. A response to the message is one threshold authentication condition for generating the reservation. Upon determining that one or more threshold authentication conditions are satisfied, the server device generates a reservation for the product.
