The North American Mustang Association and Registry was founded in 1986, and the first Mustang was registered in 1987.
All BLM Mustangs are eligible for registration, as well as Forestry Service horses, Indian Reservation horses, TRNP horses, Nevada Mustangs, and offspring of these horses.
1/2 Mustangs can also be registered. One parent must be a NAMAR registered Mustang and the other parent can be of any breed. Hardship cases are accepted and will depend on the nature of each case.
