A Nike Style code is a useful starting point for your research. The combination of code, version and details matters more than a single logo or technology name. Below you read how to compare an offered shirt with a matching reference.
1. Find the full Style code
Ask for photos of all labels and write down the full code exactly as it appears. Search for it together with Nike and the club or country. Check the result for shirt model and colour; a search result with only the right club is insufficient.
The official Nigeria 2026 Match Away page, for example, shows Style IB5205-100. That is a concrete model example. Do not draw a general conclusion from it that every older Nike shirt must have the same kind of label or the same code layout.
2. Read the name of the version
The Nigeria page names Match and Aero-FIT. Such names describe a product version. So do not compare only the design from a distance, but check which version the reference actually shows. Use the full product name and the product details side by side.
A version based on a player's shirt does not prove that the offered example was worn by a player. A claim such as match worn requires separate provenance information. A retail shirt with a player's name on the back therefore does not become a match-worn shirt.
3. Compare fabric, panels and finish
Put clear photos of the offered shirt next to the correct official or historical reference. Examine the collar, sleeves, side panels, club badge, swoosh and sponsor. Look for matches in placement and construction, not only in colour. Lighting and camera editing can affect a colour comparison.
A technology name on the shirt is an indication of the version, not standalone proof of authenticity. Labels and codes can be faked too. Several photos together must give a consistent picture of one physical example.
4. Make your question to the seller concrete
Do not only ask whether the shirt is genuine. Ask for the information with which you can carry out the research yourself.
- A photo of the whole shirt, front and back.
- An overview of all labels and a sharp shot of the full code.
- Detail photos of the badge, swoosh, sponsor and the inside of those.
- An explanation of the provenance and any printing applied later.
- A photo of damaged or replaced parts.
5. Be cautious with rules for vintage
A current Nike product page describes a current model. Do not use the requirements of that model to reject a shirt from another period. A missing modern code, a different label or a differing material name must be examined in its own context.
If in doubt, look for a source from the same season and the same version. Write down which points match, which differ and what cannot be assessed. If the code is correct but the construction is inexplicably different, the check is not finished. The shirt check helps you keep track of those open points without making an automatic statement about real or fake.
