Leicester City Ticket Collection Information
As you may be aware, we are undertaking domestic away game validations with the primary objective of getting back to receiving full ticket allocations at as many away games as possible.
To help achieve that, we need to demonstrate to clubs that we have stopped the very small minority of fans that have previously caused trouble at away grounds from receiving tickets, and ensure that the people allocated tickets are actually the supporters using them (it is our understanding that this minority did not obtain tickets directly through the Club).
With this in mind, and as agreed in the Fans' Forum, we have implemented a number of ticket checks / validations over the past few seasons for away games. Despite having validated just c3k Season Tickets since we began the process in 2013/14 (mainly due to the lack of suitable locations for collections at / near away grounds), these validation exercises are showing positive signs of working. Post-match observations from the Police and stewards have pointed to improved fan behaviour at away matches, we negotiated the full allocation for West Ham (for the first time since 2009) and additionally, Hull City have allocated more tickets to us for the EFL Cup semi-final than we are entitled to (historically they have reduced our allocation).
Therefore we will now start to apply pressure on other clubs to increase our allocation, as well as making representations to the Premier League to contest any ongoing / further reductions. However, we kindly request that fans help self-police at away games, to ensure that gangways are kept clear which will undoubtedly help our cause.
To facilitate the validation process, after a lot of planning we have managed to secure a suitable location for the Leicester City game, and will be inviting all successful applicants to collect their ticket in Leicester on the day of the game.
Supporters will only be able to collect their own ticket in Leicester, with a passport or driving license as proof of identification. Additional details of the specific collection point location, and opening times can be found here, and will also be sent to each registered ticket holder, along with a ticket exchange voucher in the next couple of weeks.
If supporters are unable to collect their match ticket as requested, they will need to contact us on 0161 868 8000 to cancel the ticket before 5pm on Sunday 8th January. Please note, around 30% of people who have been asked to collect their ticket this season haven't done so.
