Tickets for the middle Sunday of Wimbledon were made available at 15:00 BST on Saturday in an online-only sale.
An extra day has been scheduled for the first time since 2004 to help clear the backlog after rain disrupted play.
A total of 22,000 tickets will be on sale on a first come-first served basis via the Ticketmaster website, with a maximum of two per household.
They will be priced at £20 each for ground passes to outside courts, £40 for Court One and £70 for Centre Court.
Women take centre stage
The order of play will be released later in the day although it is thought there will be at least eight singles matches - mainly in the women's draw - and a variety of doubles contests.
