The U.S. Department of Agriculture (USDA) published a final rule in 2013 establishing regulations regarding the trackability of U.S. livestock moving interstate. The rule names specific methods of animal identification that are acceptable.
One of the permitted methods of identification is a 15 digit microchip that begins with the designated United States prefix 8-4-0 (ex. 840123456789012). Only USDA approved companies are granted permission to manufacture the official 840 microchip. Our microchips were submitted for testing and met all of the stringent requirements. Our microchip product, 840-ID, carries the official USDA 840 and comes in a 15 gauge needle.

Please call our office if you have questions about the 840 chips.
