There will be no cash turnstiles before the game against West Ham on Tuesday, January 31, following a request from the police.
Only Town supporters already on the Club database will be able to buy tickets on the night from the Ticket Office but are advised to get to the ground early.
Town's Ticket Office Manager, John Ford, told the Club website: "We have a strict policy of only selling tickets in the home areas to home supporters which is why only those on our database will be able to purchase tickets from the Ticket Office on the night.
"We're expecting a big crowd for the visit of West Ham and all supporters are encouraged to get to the ground as early as possible to avoid the queues."
Town supporters on the Club database can still buy tickets in person from the two Planet Blue stores (on Portman Road or in the Buttermarket, Ipswich) or under the
Ticket section on this website.
