FAQs for MREs

Military MREs (Meal Ready to Eat) are a must-have in your emergency food storage. The U.S. Military relies on MREs to give them the nutrition and energy they need to survive in the most extreme conditions. MREs are great to use during any disaster and are excellent for a “grab and go” emergency. They provide you with a warm meal that is packed with nutritional value to help you through any situation.

Here are some of the most frequent questions that we get regarding MREs:

What is an MRE?
MREs were brought into military use during the 1980s to replace heavy, bulky food supplies. MREs are self-contained meals that include a way to heat your meal. They have a durable packaging that can withstand high drops and typically have a shelf-life of about 5 years depending on storage conditions.

Do we sell military MREs?
Yes and no. Military MREs cannot be sold to the public. However, the same contractors who make MREs for the Department of Defense also make civilian MREs. These MREs are made to the same specifications as military MREs, but with a few differences. Civilian MREs come in a different packaging and don't include all of the same items, such as chewing gum, toilet paper, and other extra items.

How long will an MRE store?
An MRE will store for about 5 years, if stored at 75° F  or less. The cooler the temperature, the longer they will store. Some items in an MRE will last longer than 5 years, although the wet pack entrees typically expire within 5 years.

How do I know if my MRE has expired?

MRE packages don't have an expiration date stamped on them in the sense of a day, month, and year. Instead they have a manufacture date of when the package was made. So unless the seal is broken on the packaging, MREs can last for about 5 years, but they may lose taste and nutritional value after long periods of time. If the package is bloated or the food smells like it has gone rancid, then your MRE has expired. You can read our article on MRE Expiration Dates for more information.

MRE Manufacture DateHow do I read the manufacture date on my MREs?
MRE Manufacturers use a 4-digit modified Julian Date code to indicate the manufacture date.

This code is usually stamped on the MRE box and pouch. The location of the code can vary. The first digit represents the year, and the last three digits represent the day. So, for example, the code 7304 would mean it was manufactured on the 304th day of 2007, or October 31, 2007. Sometimes other letters representing batch numbers will be added to the end of the date code (i.e. 7304C).

You can see on the first example to the right that the code 1172 would mean that it was manufactured in 2011 on June 20th (the 172 day of the year).

The second MRE has a manufacture code of 1348. This would translate to Dec. 13, 2011.

The third MRE's manufacture code is 1306, which means that it was manufactured on Nov. 1, 2011.

Because the official longevity of an MRE is no longer than 10 years, manufacture dates are printed on packages assuming that you will not keep your MREs for longer than this time period. That is why the year in the examples above is 2011 instead of 2001.

We've prepared this Julian Date Converter Sheet that you can print off and keep with your MREs for future reference.

What is the difference between a “Full Meal MRE” and an MRE entrée?
A Full Meal MRE comes with the entree pack plus a side dish (typically fruit), a dessert, crackers, candy, and will also include a flameless heater, eating utensils, and seasoning. An MRE entree is just a single pack main dish entree without any sides or desserts.

If just want the single entree pack, don’t buy the Full Meal.

      Hey Sam,
      Since the shelf-life of an MRE is no longer than 10 years, the manufacture dates assume that you'll eat it within that time frame. So, you might not be able to tell if the date is 2001 or 2011. If you bought it from The Ready Store recently, then it's 2011. We don't have any old stock like that. However, if you bought the MREs from another online retailer (or a private sale) than we can't guarantee the manufacture year.
      You might also be able to tell if the MREs are bad because the bags will be bloated and when you open them, the food will smell bad. If that's the case, they were probably made in 2001. Hope that helps!

    why do they make the manufactured date a "secret?" are they worried that their food will rot and you won't eat it so they try to trick you into hoping you will think it is safe to eat? makes no sense. all food products i see have either manufactured on or expires on dates.

    Angel wrote a code of 3017 & 3231 on Feb. 20.
    Gary decoded the date for Angel on March 11 to mean 17th of 2013.
    According to the Ready Store it should be 17th of 2003? (The first digit represents the year, and the last three digits represent the day. So, for example, the cpde code 7304 would mean it was manufactured on the 304th day of 2007.)Can you explain who is correct???

    What if my MRE has a longer code?
    One of mine reads: 12306B2
    The other reads: P33816 12312B4

    I'm assuming they are from 2011 or 2012, but the longer code threw me off.

    Thank you for this info. Is was very useful! I almost bought MRE's from a local store that were made in 2000 and they were going to sell me those 15yr old MRE,s. After I read this article, I really tore them a new butt for selling expired food. I could tell they knew it was expired too.... Pisses me off,but I'm glad I got this info before I was on my backpacking excursion and found out the hard way!
    Thanks again!

    Does it mean the seal is broken if you can hear the contents of the MRE's moving around when you hold it?

    My code on two MRE's is 0238 does that mean that it expired back in 2000? Nothing crawling around inside of it... i don't think
