Webinar - Microchipping:
What You Need to Know Webinar

US Equestrian strives to consistently ensure the safety and welfare of both our human and equine athletes. One fundamental aspect of equine safety is microchipping. Microchips in horses allow for immediate onsite verification of horses for the purpose of safeguarding the health of each horse. This is vital, especially during times of disease outbreaks or natural disasters.

To this end, the US Equestrian Board of Directors approved a new microchipping rule during the 2023 Mid-Year Board meeting. Beginning December 1, 2025, under GR 1101.1, all horses competing in USEF-licensed or -endorsed competitions must be microchipped with a 15-digit ISO compliant 11784/11785 chip.

If you have specific questions about recording your microchip, please email [email protected].

You can also go to your USEF Member Dashboard to report a microchip for your horse. 

  • For a new horse - go to new horse recording.
  • For an existing horse - click on the horse tile under "your Horses" and choose "Update Microchip."
