An A# precedes the registration number of horses registered with the Half-Arabian Horse Registry (HAHR). It defines the number of consecutive crosses to a Purebred
Arabian and certifies the minimum degree of Arabian blood for that horse. At no point in this progression will the Arabian blood reach 100%, therefore its prodigy
will never be eligible for registration as a purebred with the
