Beef Identification (RFID)

Starting March 1, 2007, all cattle leaving their Michigan premises must be tagged with a radio frequency identification (RFID) tag. Although the USDA has made the National Animal Identification System voluntary, Michigan premises registration and the Michigan Animal Identification System has been established to aid efforts in eradication of bovine tuberculosis and is mandatory.

Register Premises

You must have a premises identification number prior to purchasing official RFID tags. If you have completed a herd bovine tuberculosis test, you have already been assigned a premises identification number. To obtain a premises identification number, call the

Michigan Department of Agriculture and Rural Development at 517-284-5670 or register online
To track animals, animal health officials must know where they are born and where they are moved. Therefore, uniquely identifying locations that manage or hold animals is the first step in traceability. Each premises in Michigan that participates in animal production and (or) commerce will be identified with a unique seven character identifier (for example, A123R69), called a premises identification number. This number is the same as that which will be used in the National Animal Identification System, developed by USDA. Information that will be associated with your premises identification number in MDARD’s database includes:
Name of Entity
Owner or Appropriate Contact Person 
Street Address, City, Zip Code of the farm 
Contact Phone Number Operation Type (e.g., farm, market, processor, etc.)
