Warning: Fake Football Shirts Now Feature Correct Product Codes - 2 Ways to Still 'Code Check' Fake Kits

Update - Sunday, June 7, 2026: Even if counterfeit kit might now have the correct SKU (Stock Keeping Unit), there are still at least two ways to identify fake Nike kits from the labels, but it is way harder.

1. Barcode Check (Method by vladieboi)

Every authentic Nike kit has a correct barcode, while fakes come with a wrong barcode. You can reverse check the number seen on the barcode of the kit - if it directs to a wrong product, it is probably a fake.

1. Nike Authentic Label Check (Method by @amyalby2904)

Every nike kit features a special tag with a unique 10-digit-code on the lower left hem. Every official Nike kit has a different code - fakers copy the same code, which means that if this code is seen on another shirt then it is 99,99999% a fake (the fakers likely copied it from authentic Nike kits, and used that code - but the chance is to have a official with a copied number is lower than winning the main price in any lottery.

For years, one of the most reliable methods for football shirt collectors to verify authenticity was to simply search the product code found on the small inside wash label. If the search engine results displayed a completely different piece of apparel, the shirt was an obvious fake. However, things could have changed forever now.

Apparently, counterfeit manufacturers have updated their production methods to actively bypass this standard verification check. As highlighted by @niclasico, trusted retailer of authentic classic kits, there are counterfeit versions of the Brazil 2026 World Cup home and away shirts with the correct Nike product codes on their internal labels.

When an unsuspecting buyer types these copied codes into a search engine, the authentic Brazil jerseys appear in the shopping results, providing a false sense of security and incorrectly validating the fake shirt's legitimacy.

So far, the correct product codes have only been seen for Brazil fakes. It seems well possible that counterfeiters will apply this same tactic to the most popular kits from Adidas, Nike, and Puma.

With the classic label code check no longer serving as a foolproof authenticity test, buyers navigating resale platforms will now have to rely much more heavily on closely inspecting fabric quality, stitching, crest application, and overall cut to spot fakes.
