Animal Identification is a national program to identify animals and track their movement between premises. The information is used by Animal Health Officials to manage disease. The goal is to be able to identify where affected animals have been within 48 hours of confirmation of a disease outbreak or other animal health event. WSDA began voluntary Premise Registration in January 2005. Knowing the locations of animal premises is vital to Animal Health Officials when they are managing an incident. A unique premise number is assigned to a location permanently. A premise number may be requested by the landowner, the producer using the land, or the person.
