A few states might allow copy certification on the part of the Notary which means that the notary would officially vouch for the truthfulness and authenticity of the copy.

However, most states do not allow this. Copy certification by document custodian is an embellished Jurat. It requires the signer or document custodian to swear to the truthfulness of the copy of the document. It is generally best that the notary also inspect the document to make sure it is a true copy and perhaps write an informal note stating the same. This is how I was trained when I was a Notary Public.
