We recommend you make sure you have ID with you when attending any WeGotTickets event. Any official ID, either with a photo or signature, should be fine. If the venue needs you to bring anything unusual we'll specify this in your confirmation email.
You will also need proof of age or concessionary status, if applicable.
PLEASE NOTE: You do not need to print your confirmation email - and it's more than 400 times better for the environment if you don't (see here)
