Just went through this with our Lab.
OFA Eye FACs short story The following example illustrates the anticipated format: LR-EYE-100/24M/VPI. In this example, the first two characters indicate the breed, in this case a Labrador Retriever. EYE indicates this is an OFA eye number. 100 would indicate this is the 100th Labrador assigned an OFA eye number. These numbers are issued sequentially within breed. 24M indicates the age in months at the time of evaluation, and the sex. VPI indicates that the dog was permanently identified via microchip or tattoo and the examining ophthalmologist verified the id during the examination. Other possible suffixes would include NOPI (no permanent identification provided), or PI (permanent id provided on the application but not verified by the examining ophthalmologist). Only dogs with verified permanent identification will have their normal results automatically shared with the AKC for inclusion on their registration and pedigree documents. Breeder option codes will be noted on the OFA report and on the OFA website.
OFA FACs 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.
