Hi there and welcome
The number does not tell anything helpful, only the store, drading of the paper and this has no records plus consistently changed depending on dates, so you cannot look back and see which store applied this.
The only way to date is
* If the back of a photo has the printing 'Velox,' the photo dates circa 1940s-50s.
* If the back of the photo has the three line printing 'Kodak/Velox/Paper,' the photo dates circa 1950s-60s.
* The printing 'A Kodak Paper' was commonly used in the 1960s and early 1970s.
* The thee lined printing "THIS PAPER / MANUFACTURED / BY KODAK" was commonly used in the 1970s-80s. If you have a photo that is advertised as being from 1979, the presence of this branding doesn't prove the specific year of 1979 but is consistent with the date.
So you can date on this, but not via the numbers on the back of it sorry.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
