As long as the shipping label for your order has not yet been printed, you can still edit your shipping address.
To see if you can still edit your shipping address, please login to your seetickets.us account.
Click the blue DETAILS button next to your purchase.
If you see the Edit Shipping Address link next to your address, then you can update the address.
If you do not see the "Edit Shipping Address" option, unfortunately no edits can be made and we are unable to re-ship tickets.
