manufacturing week and 0034 running manufacturing number.
•
8 digits: For example, in 14250125, 1 denotes manufacturing country (1 = Finland), 4
manufacturing year (2004), 25 manufacturing week and 0125 running manufacturing
number.
•
10 digits: For example, in 1173200725, 1 denotes manufacturing country, 17
