Have you ever noticed the mysterious three-digit number printed on the side of your egg carton?
Most people see it and assume it’s a factory code, inventory number, or random packaging detail. In reality, that small number can tell you exactly when your eggs were packed—and it may be one of the most useful freshness indicators available.
Understanding how to read this code can help you make smarter decisions about food storage, egg freshness, and kitchen safety.

What Is the Three-Digit Number on an Egg Carton?
That three-digit number is known as the Julian date or pack date.
It represents the day of the year the eggs were packaged.
Examples
- 001 = January 1
- 032 = February 1
- 120 = April 30
- 200 = July 19
- 365 = December 31
So, if your carton displays 120, the eggs were packed on the 120th day of the year, which is April 30.
Important Note
The Julian date is not the expiration date.
Instead, it tells you when the eggs entered the packaging process, giving you a better understanding of their age.
