Presidential Modification Delays Microchip Requirements

Please read this important statement affecting the remainder of the 2026 competition year.

FOR EVERYONE ENTRING USEF LICENSED OR ENDORSED COMPETITIONS: GR 1101.10
MICROCHIPS: THIS IS WHAT YOU NEED TO KNOW

USEF competition horses must have a ISO compliant (11784/11785) microchip embedded in their nuchal ligament, and the number recorded by USEF, by December 1st, 2025. It is the owner/riders responsibility to be sure this has been done.

If you are certain your horse(s) are microchipped, confirm that the number is recorded on the USEF website.

  1. Sign in to your account www.usef.org
  2. Click (upper right) account icon
  3. Click my dashboard icon
  4. Scroll down to your horses
  5. Click each horse
  6. Confirm that there is a 15-digit microchip number in the horse information section. No letters.

If your horse has been microchipped but you are unsure if it is ISO compliant:

  1. The number should have 15 digits, no letters
  2. The radio frequency should be 134.2 kHz. (From the packaging or your vet might know.)
  3. Biothermal chips are compliant
  4. Most “breed chips” are compliant; check for 15 digits and the kHz.
  5. Be sure this is recorded on the USEF website (as described above).

If your horse has not been microchipped, you can arrange for this by your local veterinarian.

  1. The cost is modest; most of your fee will be the vet visit cost.
  2. Placement does not require sedation; the insertion needle is about the size of a vaccination needle, and any initial swelling is minor. There is no “downtime.”
  3. Follow the steps above to record the number on the USEF website.
