Sheep & Goat Identification
Sheep and goats moved in interstate commerce have both individual identification requirements and flock identification requirements. If you are planning to use microchips for identification you will require a Premises Identification Number (PIN) in addition to your flock ID. With other identification types, such as RFIDs and registration tattoos, the PIN is still available but it’s optional. USDA has additional information on sheep and goat identification requirements and options.
The National Scrapie Eradication Program is a USDA program that provides flock IDs and official eartags for sheep and goats. You can call 1-866-USDA-TAG for flock ID requests and tag orders.
