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).

Return Policy Products purchased directly from our website have to be returned to our warehouse for a substitution to be made. The products can't be exchanged at a retailer. A product can only be replaced with another product of equal or lesser amount.

Look for the tag on the product which will have the size and other product information mainly inside the shoe that is behind the tongue of the shoe. Real Adidas shoes have tags with serial numbers for the left and right shoe. However, a fake product will have the same serial number on both shoes.
