When any parcel of land has been coded under the county code system the county auditor shall make a certified copy thereof and cause the same to be recorded in the office of the county recorder, except in cases where the county auditor has noted upon a deed or other instrument conveying land that the land described therein has been coded as provided in section 272.194 and that the instrument has been subsequently recorded in the office of the county recorder, in which case the auditor need not file another certified copy of the coded tract. In such cases reference to the place of recording shall be to the book and page wherein the instrument conveying the coded tract is recorded in the office of the county recorder.
