The Breeder’s Certificate:

Pre-printed registration applications — called the Breeder’s Certificate — are issued by APHA to stallion owner who submit their stallion breeding reports to APHA by November 30 of the breeding year. This pre-printed application lists the sire, dam and breeding information, as well as the Breeders Control Number that’s unique to this specific breeding and year.
If you don’t have a pre-printed Breeder’s Certificate, don’t worry. You can use the blank registration application and fill in the applicable information yourself. Make sure the owner of the sire at the time of foaling and the owner of the dam at the time of breeding sign that document in their applicable sections.
