If the venue has changed from the venue printed on your ticket, it's very likely that the ticket is still valid but the best way to confirm is to contact your seller using the contact details provided in your purchase order confirmation and ask them to forward across any correspondence on the venue change. This will provide the exact information as to whether the same tickets are valid, or if a new set will be released.

You may also be able to see information about a venue change on the original vendor's website event page for further reassurance.

If new tickets are released as part of the venue change - your seller will need to forward those to you.
