There are rare situations in which the donor cannot produce proper identification, such as a self-employed individual. In these cases, the collector should make a note in the Remarks section of the CCF that the positive identification was not available. The individual is then asked to provide two items of identification bearing his or her signature. The collector then proceeds with the collection. When the donor signs the certification statement (pink copy of the CCF), the collector compares the signature on the CCF with the signature on the identification presented. If the signatures appear consistent, the collection process continues. If the signature on the CCF does not match the signatures on the identification presented, the collector must make an additional statement in the Remarks section noting that the signature identification is unconfirmed.
