Microchipping Information
AMHA members are encouraged to support the United States Animal Health Association’s (USAHA) Resolution 18. This resolution addresses the standardization of microchipping our horses with International Standards Organization (ISO) compliant 11784/11785 microchips in the left nuchal ligament of the equid as a method of official identification. In addition, USAHA urges support of the utilization of temperature sensing ISO compliant microchips as a means for identification and health monitoring.
Effective on December 1, 2026 (the 2027 competition year - please see the *Presidential Modification dated 01/12/2026), USEF rule GR1101.10 will require every horse entered in a USEF-licensed or -endorsed competition, regardless of breed, discipline, or rating/level to be microchipped with a 15-digit ISO compliant 11784/11785 chip. A page dedicated to information regarding microchipping is on the USEF website.

USEF Rule Overview
As a reminder, this rule will require all horses to have a microchip to be eligible to compete at a USEF licensed competition. This microchip number must be on file with USEF and, once recorded, will remain with the horse’s record. It is the participant’s responsibility to report the microchip to USEF. The microchip numbers do not need to be collected by the competition; however, USEF will ask competitions to verify that a chip number is on file before accepting the entry.
Reporting Tool
USEF has created an easy-to-use online microchip reporting tool that is available to anyone (owner, trainer, barn manager, secretary) to report a microchip for their horse. This tool can be found at https://members.usef.org/
Microchip Resources
USEF has developed a microchip resource webpage which has many useful resources, including:
USEF has also recently published the following four infographics that will help answer general questions at your competition:
Video Resources
USEF has also produced two video resources that can help further explain microchips.
- Webinar – Presented by USEF’s Equine Health and Biosecurity Veterinarian Dr. Flynn and Merck’s Dr. Lacolla, this webinar provides a more detailed background on microchips, how they work, and how USEF’s rule will be implemented. This video clip is about an hour long but is full of great information regarding microchips.
- Learning Center Video - In this video, Rood and Riddle’s Dr. Metcalfe along with USEF’s Dr. Flynn provide a short tutorial on microchips, how they work, how a microchip is implanted and how horse health can be monitored, specifically with the temperature taking biothermal microchip.
