‘840’ is the United States Country Code for identification, recognized around the world.  When a microchip begins with the USA country code of ‘840’ you can be sure of these things:

  1. Microchip numbers with an 840 prefix are made only by USDA approved companies.
  2. Companies that manufacture the 840 microchips for animals must go through the rigorous USDA approval process.
  3. The approval process is stringent and emcompasses a high level of quality control testing.
  4. These chips are ISO and FEI approved.
  5. The 840 microchip can be used for horses if desired.  Larger facilities, veterinarians or those who move horses interstate should consider using the 840 chip.
  6. Our 840 microchips are the same price as our regular chips.

“U.S. Department of Agriculture (USDA) published a final rule in 2013 establishing regulations regarding the trackability of U.S. livestock moving interstate. One of the permitted methods of identification is a 15 digit microchip that begins with the designated United States prefix 8-4-0 (ex. 840211011000122). Only USDA approved companies are granted permission to manufacture the official 840 microchip.”

Our 840-ID Microchip meets all USDA requirements.
