From 1957-1965 the code configuration on the slim lighters differed from the regular lighters (See Date Code Chart below). The appearance of the word "Zippo" in the bottom stamp provides another clue to dating.
There have been three major changes, as shown in inset.
From 1933 to the mid 50s the word Zippo was stamped in block letters. From August, 1949 through July, 2002 Zippos were also produced in Niagara Falls, Canada - the only place other than Bradford, PA where they were ever produced.
While the information for dating a Zippo is widely available, it isn't that handy to find it all in a single location.
This should provide the information to fix a relatively precise date for any Zippo lighter.

The good news is that many in Congress took the time to understand and the Innovation Act was stopped on the floor. AI runs not only our power grids, but our tanks and ships.
Congressman Issa (R-CA) and Congressman Goodlatte (R-VA) have attempted to revive it this year, but their cries now fall on educated ears. We will soon be mired in the swamp of a national security disaster as China moves even further ahead and we are forced to purchase these products from them. It seems every month, China’s government announces a new program or directive intended to further strengthen their patent system. Cases are resolved by the court in about 10 months, and to get through the courts to a final decision, it costs around 0K, both much more favorable than here. When they win, injunctive relief is almost always awarded.
The smoke was intended to cloud what these huge companies really wanted – to destroy the patent system for small inventors and startups so they can perpetuate their monopolistic companies. Not surprisingly, in communist China, the startup market is booming, growing by 23%.
But the battle of ideas during the rush to pass the Innovation Act opened the debate up. As a result, China has taken the lead in swaths of new technologies, including technologies critical to our national security like artificial intelligence (AI).
But there are two important statistics about China that are particularly revealing.
The first is that 100% of foreign plaintiffs were awarded injunctive relief last year. China is laying the groundwork to turn 1.3 billion people into an army of individual inventors. have gone the exact opposite direction – to our own peril. Not only are there maintenance fees and other costs in maintaining a patent, but at any time the patent can be plunged into the corrupt PTAB political courts dumping hundreds of thousands of dollars of costs on whoever owns the patent.
Slim lighters were first introduced in 1956, with a flat bottom and no date code.
