More important for COO: enter a \"0\" if only two numbers are in front of the letter e.g. 62K1064 – you will only find the COO if you enter 062K1064.

If you find a lot number such as TO09019TO - enter the lot number 09019TO without the first two letters.
If you find a lot number with a filling-code such as 05427ES–021 - enter the lot number 05427ES without the filling-code -021.
If you find a lot number with a filling-code such as STBB0728K9 - enter the lot number STBB0728 without the filling-code K9.
