Beginning January 1, 2013, the FEI General Assembly has made a change in veterinary regulations that all horses to be newly registered with the FEI must be microchipped. The microchip must be compatible with ISO 11784 and ISO 11785, and all microchip information must be entered into the horse's passport and reported to the USEF.

Microchip numbers consist of 15 digits of which the first three identify the manufacturer or country code and the remaining numbers are unique to each horse. A microchip carries the identifier that will be associated with a specific horse from the date of implant until the animal's death.
Horses are microchipped on the left side of the neck, halfway between the poll and withers and approximately one inch below the midline of the mane, into the nuchal ligament.
Owners should check with a veterinarian to schedule microchipping for their horses. The USEF recommends that horses be scanned for the presence of a microchip before a new chip is implanted, especially in the case of horses that have had more than one owner.
