Hey there,

Every Hatchtopia Life Plush Toy comes with two codes, A Toy code and a HFF code.
Toy codes can be scanned in to redeem a Hatchimal egg, HFF codes are used to give to a friend.
If you and a friend both exchange your HFF code you will be added as friends and can share prizes and gifts as well as send them stickers.

However you cannot scan your own HFF code, These codes can only be given to a friend.
You can tell the difference between a HFF code and a Toy code by the markings on the back.

Please let us know if this helps!
Thanks!
