Where to find the number

On meat and poultry, the establishment number is printed inside the round USDA mark of inspection, as EST. 1234 for meat or P-1234 for poultry. It can also appear near the mark or on the side of the case. The brand name on the front often belongs to another company: the number shows the plant. What the codes on food packages mean.
