Passports | GB Registrations

Weatherbys is a registered Passport Issuing Organisation (PIO) with responsibility for providing passports for Thoroughbreds born in Great Britain.  

By law all equines must have a passport, which stays with them for life. Our work in issuing passports is vital for ensuring transparency and traceability of the Thoroughbred throughout its life.

Our digital platform General Stud Book Online provides easy access for breeders and owners to register their produce and register their equine for a passport to be produced.  

Weatherbys maintains all of these details for Thoroughbreds and Non-Thoroughbreds, of which we maintain the Non-Thoroughbred Register for horses which are for non-racing or breeding purposes.
