All breeders wishing to use a "Stud Name" for registering ponies must seek approval from the Central Prefix Register. This is quite easily done by completing a Prefix form and returning it with the fee of £100.00 to SPSBS who will forward it to the Central Prefix Register on your behalf.
New prefixes must be between 3 and 25 characters long with no spaces, hyphens or apostrophes. Final approval rests with the Central Prefix Register.
To check availability of a particular name look on the Central Prefix website: www.centralprefixregister.com
Extensions of a current prefix are also available. Again simply complete an Extension to Prefix form and return directly to the Central Prefix Register with the correct fee and your certificate. They will then contact the Secretary to seek approval prior to informing the applicant directly.
