The British Lion mark explained

All Class A eggs have to be marked with a code showing the type of farming system, country of origin and farm production unit. The “red lion” egg stamp and code is explained in the graphic, below.

Top line of code

First part, a number denoting the Farming Method:

• 0 = Organic
• 1 = Free Range
• 2 = Barn
• 3 = Cage

Second part, characters showing the Country of Origin (e.g., UK)

Third part, a numeric code denoting the actual farm where the eggs were produced (e.g., 54321)

Bottom line of code

The characters 'BB' (meaning 'Best Before'), followed by the best before date (e.g., 15APR)

The Lion Mark

To the left of the code is a graphic of a Lion, showing that the egg is from hens vaccinated against Salmonella and produced to a strict Code of Practice
