If the donor is an owner-operator or self-employed, signature ID may be used. If the donor has no photo identification, the collector should supply appropriate comment on the “Remarks” line that photo identification was not available. The collector may proceed with the collection if the donor can provide two items of identification bearing the donor’s signature. After the donor signs the certification statement, the collector should compare the donor’s signature with the signatures that appear on the identification presented. If the signature match, the collector list on the “Remarks” line the two items of identification used to identify the donor and states “signature identification appears to match.” If the signatures do not match, the collector should state “signature identification is unconfirmed.”
