What is date of Heinz ketchup bottle with number 255 on bottom of bottle?

The number 255 on the bottom of a Heinz ketchup bottle typically indicates the production date as part of the manufacturing code. Heinz uses a system where the first digit represents the year, and the following digits indicate the day of the year. Therefore, a bottle marked with "255" would be produced on the 255th day of the year, which usually falls in late September; however, the specific year would be needed for exact dating. For precise dating, it’s best to consult Heinz directly or refer to their official guidelines on production codes.
