Effective January 1, 2001, the OFA adopted a policy acknowledging animals that have been submitted for inclusion in its databases that have permanent identification in the form of tattoo or microchip. Animals not permanently identified will continue to be evaluated; however, they will be issued a number clearly indicating that the animal has no permanent identification. Animals with permanent identification will have a suffix of PI added to the OFA number. Animals that are permanently identified AND have had the identification verified by the attending veterinarian will have a suffix of VPI applied. Animals with no permanent identification will have a suffix of NOPI applied. Effective 1/1/08, only dogs with verified permanent identification (VPI) will have their OFA data transmitted to the AKC for inclusion in their database.
