1. A computer-implemented method for verifying authenticity of electronic ticket data associated with electronic tickets to events, comprising: generating, at a verification system, a plurality of unique identifiers, each unique identifier of the plurality of unique identifiers corresponding to an electronic ticket to an event, and each unique identifier of the plurality of unique identifiers enabling a user to gain entry to a venue associated with the event; receiving, at an assignment system and via an interface, a communication from a first user device associated with a first user, the communication corresponding to a request for an electronic ticket to the event, the electronic ticket being associated with electronic ticket data indicating that the electronic ticket is assigned to a second user device associated with a second user, the electronic ticket data including a unique identifier of the plurality of unique identifiers, and the assignment system enabling re-assignment of previously-assigned electronic tickets, and when a previously-assigned electronic ticket is requested to be re-assigned to another user device, the verification system is automatically used to verify the authenticity of the previously-assigned electronic ticket before enabling the re-assignment; transmitting, at the assignment system, a verification request to the verification system in response to receiving the request, the verification request including the electronic ticket data; automatically initiating, at the verification system, a verification process in response to receiving the verification request, the verification process verifying whether the unique identifier corresponds to a valid electronic ticket to the event, the valid electronic ticket corresponding to a unique identifier of the plurality of unique identifiers, wherein when the verification process verifies that the unique identifier corresponds to a valid electronic ticket, the electronic ticket is enabled for transfer from the second user device to other user devices; receiving, at the assignment system, an indication that the verification process has completed, the indication indicating that the unique identifier corresponds to a valid electronic ticket to the event; and in response to receiving the indication, facilitating transfer of the electronic ticket from the second user device to the first user device.
