Coventry City are in the process of updating season ticket cards.
The club have said: "Existing Season Tickets will be updated for the new Season for supporters who have not moved price category or seat location for the new season. If fans have moved price category/seat location, they will be issued with a new card.
If you no longer have your Season Ticket card from last season, you can contact Shelagh.Brock@ccfc.co.uk to organise a new card to be sent.
From 5th July onwards, only new cards will be issued – regardless of whether seats/prices have changed, old cards will not be able to be updated."
