My Jamine and Butch had CKC registration papers. I chose to register them ACA (American Canine Association) because my other yorkies are either ACA or AKC. I had to send a COPY of the CKC papers and pictures of them along with their registration form (which can be retrieved from their website).
You can call them at 800-651-8332 if interested in their registry and want to question them about it.
Good luck.
