adidas product code Like their rivals Nike, adidas do a good job of providing an easily accessible code across all their shirts. The code (also known as an International Article Number), found on a small tag usually on the inside of the collar, is 6 digits long consisting of 2 letters and 4 numbers.

Tip 3: All genuine Adidas products have serial numbers on the tags affixed to them. The tags have the size and product information on the inside of the shoe (behind the tongue).

Adidas now has global corporate headquarters in Herzogenaurach, Germany and many other business locations around the world such as London, Portland, Toronto, Tokyo, Australia, Taiwan and Spain.
