What does AKC require to accept the certification?
You must have your AKC registration number. In order for OFA and CERF information to appear on a dog’s pedigree, AKC has required the dog to be permanently identified since 1996 and CERF since January 2001. All dogs that wish to obtain a CERF number must be permanently identified via tattoo, microchip or DNA profile number prior to testing and certification.
