We never list seat numbers on our site because the seller may have many seats in a single row and there is no way of knowing which ones they are sending to each of their customers. However, tickets purchased in a single order will always be side by side unless the ticket details, which are displayed at checkout, state otherwise.
Don't be alarmed if you purchased tickets to a theater event and they appear to be separated. Most theaters split their seating and have odd numbers on one side and evens on the other. If this is the case, seat #1 and seat #3 would be next to each other.
If you see two listings in the same section and row or if you place two separate orders for what seems to be the same inventory, we cannot guarantee that the seats will be together because they are in different orders and possibly coming from different sellers.
