In order to add a higher level of integrity to the OFA databases, all OFA application forms have been modified to include an area for the attending veterinarian to indicate whether or not they verified the supplied permanent identification.
Veterinarians are encouraged to make the verification part of their standard procedure for taking OFA hip and/or elbow films. Owners are encouraged to brief their vets on this policy change and when necessary proactively request that the verification step be done.
Dogs with acceptable permanent ID are assigned a PI suffix to their OFA number, dogs without permanent identification are assigned a NOPI suffix.
 
Application for Verification of Permanent Identification
 
The OFA’s policy regarding permanent identification is an extension of the AKC’s policy in that the AKC will only accept OFA numbers into their registry for inclusion on registration papers and pedigrees IF the dog is permanently identified and verified. While DNA profiles are able to uniquely identify individual dogs, it is also the AKC’s policy to limit permanent identification for health screening purposes to tattoo or microchip. The rationale is that DNA profiles are not immediately verifiable, they require a sample to be taken and subsequent laboratory analysis. The AKC’s premise is that tattoos are visually verifiable immediately, microchips are immediately verifiable using a scanner, and that the verification should be done at the time of testing.
