Buying Eggs in Korea: Read the Shell Code in Three Parts

The small stamp on a Korean egg gives three kinds of production information. Read its date, farm code and housing number separately. Then turn to the carton for the use-by date and storage instructions. Each part answers a different shopping question.

Split the usual stamp into 4 + 5 + 1

The Ministry of Food and Drug Safety’s September 4, 2026 guide (IN KOREAN) explains the usual ten-character stamp. Its teaching example reads 0827 M3FDS 1. Spaces here make the three parts easier to see.

Part of the exampleWhat it means
0827 · first four digitsLaying date: August 27
M3FDS · next five charactersProducer’s unique farm code
1 · final digitHousing system: outdoor access

The date uses month followed by day. The shell stamp gives no year, so read it together with the package information.

The final digit describes the hens’ housing: 1 = outdoor access; 2 = indoor barn; 3 = improved cage; 4 = conventional cage. The ministry distinguishes these numbers from egg quality grades such as 1+, 1 and 2, shown on the outer packaging. Compare housing and quality as separate fields.

Use the full code for a history check

Food Safety Korea’s egg-information page (IN KOREAN) links to the livestock traceability service. It says to enter all ten characters exactly to check the egg’s history. Use the code on your own egg.

If a lookup fails, recheck similar characters. The official page flags O and 0, I and 1, U and V, and B and 8 as common typing mix-ups. Take a clear photo before entering a faint stamp; avoid guessing missing characters.

Check the carton before choosing

Look for 소비기한, the use-by date, and 보관방법, the storage instructions. The National Food Safety Information Service’s August 28, 2026 reminder (IN KOREAN) explains that the use-by date depends on following the labelled storage conditions.

Food Safety Korea’s storage rules (IN KOREAN) require eggs already refrigerated to remain refrigerated during storage and distribution. Follow the carton’s storage directions at home.

Our practical shopping tip: compare the shell information and carton together, then choose a pack size you expect to use within its labelled period. Keep the package details with the eggs so the use-by date remains easy to check.
