Do I need to affix anything to the animal after I electronically tag it? Yes, the electronic tagging process will include the attachment of a unique validation code that you will be given through the app after a successful harvest. Cell service will not be necessary to receive the validation code. Hunters can choose a material of their choice such as flagging or tape, to write the validation code on, and attach to their successful harvest. The attachment of the validation code will be your legal proof of tagging.
