SeatGeek lists tickets from many markets and sellers, but not all markets support promo code use. Many promo codes also have restrictions on them, including but not limited to: minimum purchase amount, first-time buyer only, and expiration date. You can view restrictions for any code you have applied on your account page.
If you’ve got a promo code you want to redeem, simply change “All Ticket Types” on the event page to “Promo Eligible” and this will filter the listings for you! If your promo code is eligible to be used then you’ll see the discount reflected at checkout!
