You have bought a new horse and you want to update the profile, FEI Passport or FEI Recognition Card?
As an Athlete, you don't have the possibility to make a correction to a horse's profile, FEI ID number and/or make a Passport / Recognition Card by yourself.
Please note that the FEI is also not able to modify a horse profile, FEI ID number, FEI Passport or FEI Recognition Card on your behalf.
Only your National Federation can update an horse FEI profile, a Passport or Recognition Card.
You will find the list of National Federations in the FEI Database.
