The egg code: what the shell says and what the ES 14.00616/GC on the carton means
Each egg we produce carries a code printed on its shell, which identifies the farm of origin and guarantees full traceability.
On the shell
The legend “Marcado del huevo” (egg marking), printed in green on our class L carton, explains it:

- First digit: how the hens are kept.
- Next two letters: the Member State of production.
- The rest of the digits: the farm of production.
On our eggs the two letters are ES, for Spain.
On the carton
The carton adds four details: the packing centre ES 14.00616/GC, class M or L, Class A and the best-before date.
