Serial Codes were special codes that could be input in the game for various rewards. This feature was removed alongside the Invite Friends to get Moneko feature in the Version 4.3 Update.

Classification and Function

Gift Codes

These were one-time use codes that were sent to the winners of PONOS' contests. These codes would give the player items such as XP, Cat Food and Tickets.

Secret Codes

These were codes that when used, would unlock hidden Cat Units.

Merchandise Codes

These were one-time use codes that were included alongside Battle Cats merchandise (or in the case of Mob Cat and the 5 Kishidan Collaboration Units, movie tickets and CDs). They would give items or Cat Units.
