Reading Candy Bar Freshness Codes

I'm a candy collector collecting old candy wrappers to build my vintage candy wrapper collection for all to view.

Freshness Code, Date Codes, Stamp Code, Expire Date or Manufactures Code

A lot of the smaller companies just stamp a Best Before date on the package.

NECCO – Made Date

307191 – 3 is Mass. company, 071 is the 71st day of the year, 9 is the year 2009 and 1 is the shift they were made on which is the 1st .

Hershey – Expire Date

First number is year (0-9) second letter is month (A-L, which is Jan-Dec). However, some codes are like JAN2010, which needs no explanation.

Mars – Made Date

First digit is year next two digits are the week of the year it was made

Nestle – Made Date

They use Julian code so the first four digits are (1 digit year followed by 3 digit day of the year)

  1. I’m in charge of rotating the candy for a retail store and to save time I made an android app the converts these secret dates. You type in the 2 3 or 4 digit code and it spits out a readable date.
    3160 = June/09/2013 312 = Mar/20/2013 3L = December of 2013
    The app is free on the Google play store just search Eastwestmain or Code Date Converter
    Thanks

  3. What is the product shelf life from the manufactured date?

  4. Wow. Do you know how to convert a bundle of digits on the Tootsie Rolls bag? It reads: F 27 4 1 3 3 05:59. I take it the last 4 digits represent the time of the production. F could be the month (April), and 27 could be the day? What about the rest of them? 4133…hmmm.

  5. This is what I’m thinking. The F 27 (might) represent the date that is April 27.

    Now on to 4133. 4 could refer to a certain facility where the candy was made; 13 = year 2013; the last digit 3 = 3rd shift as is further supported by the time 05:59 that is a minute short of 6 am.

    I wonder if I got it right.
