You can upload e-ticket PDFs on seatgeek.com and in the iOS or Android app. Visit “My Tickets” on your computer and you'll see a box near the top of the page with some more information to help you get started. On iOS, head over to the “My Tickets” tab where you'll find a helpful “Add” button in the top right corner.
By adding an e-ticket to SeatGeek, you use your mobile device as your ticket to events that support mobile entry. Adding tickets to SeatGeek also makes it easy to send the ticket to someone else or list for sale on the SeatGeek Marketplace.
