If your goal is to ride for placement in any of the AERC award programs, or if you just want accurate mileage records maintained, you MUST register your horse(s) with AERC and provide the assigned ID at all events. This ID number will remain with the horse throughout his lifetime and will not be re-issued. Each new member is allowed to register one horse free of charge. Any additional horses may be registered for a fee of $10 per horse. Payment by check or VISA/Mastercard accepted. If you use online registration - you must pay by credit card.
