What are Webkinz secret codes?

Webkinz secret codes are special alphanumeric sequences found on tags accompanying the retail toys. Purchasers of the stuffed animals can enter the code on the Webkinz website to gain a digital version of that individual pet in the online game Webkinz World.

This virtual game world allows players from around the world to interact, adopt pets and purchase in-game items with virtual money. While a Webkinz account is only good for one year, purchasing and registering a new pet extends the account's membership for another year. Ganz, the creator of Webkinz, makes a variety of other toys that can be registered with the account and used in-game.
