Since 1955, most Zippo lighters have carried a date code stamped on the base.Originally this was intended as a quality control record, so that lighters returned for repair could be identified as to when they were manufactured and if, for example, a number of lighters were returned with the same fault then Zippo could identify a possible defect in the manufacturing process or even a supplier of one of the components. As there were some alterations to the positioning of the text on the bottom line, some codes were used twice, therefore close attention should be paid to the text on the bottom line for lighters with 7 or 8 dots. 1955-1965 Dating guide The next set of codes used upright lines either side of the word Zippo. Again 8 lines were used for the first year of the series, with one line being removed each year.Early 1986 lighters of this series do have earlier date codes.

1982-1986 Dating guide In July 1986 the line symbols were discontinued and the lighters were then identified by a series of roman numerals.These were placed to the left of the word Zippo, which left the space to the right free.
