Club members will also receive priority.
Over 6,000 fans - the list is still growing - have shown an interest in becoming new season ticket holders from next season.
Ticket office manager Karen Murphy said: "Season tickets have always increased by approximately 3,000 per season and that underlines the phenomenal support we have at Tottenham Hotspur.
"The continued growth of the number of season ticket holders at the club has meant we've had to look closely at the situation and we will limit season tickets to 23,000 next season.
"We are well aware of the high level of interest in becoming a season ticket holder and as a club, we feel our long-term future is with our younger fans.
"We have received over 6,000 applications to date for new season tickets so for the time being we have decided to give priority to families and children.
"But we advise anyone who wants to become a season ticket holder next season to register here as soon as possible."
