adidas Authenticity Guide: Labels, Logos and Product Codes
adidas has used the Trefoil, Performance branding and several label systems across sportswear and adidas Originals. Because the correct details depend on range, product type and production period, authenticity should be assessed through a combination of branding, product information and construction.
First identify which adidas range the garment appears to belong to. Then compare the logos, labels, product code, care information and physical construction with that type of item. Avoid rules that assume every genuine adidas garment should look the same.
1. Identify the logo and range
The Trefoil is strongly associated with adidas Originals, while Performance branding appears across many sports products. Logo use has evolved, so make sure the branding is plausible for the claimed range and age rather than expecting one mark on everything.
2. Inspect embroidery, printing and stripes
Lettering, logos and the three-stripe treatment should be cleanly formed and sensibly positioned for the product. Older pre-owned pieces can show fading, cracking or minor thread wear, which should be distinguished from poor original execution.
3. Check the product or article code
Many adidas labels include a product or article number. Search results can help establish whether a code corresponds with the same type, colour and design. Codes can be copied, however, so a match is supporting evidence rather than a guarantee.
4. Read the care labels
Look for consistent sizing, fibre content, washing symbols and country information. Printing should be legible for the garment’s condition and the details should agree with one another. Obvious spelling errors or contradictory information deserve closer attention.
5. Examine the complete construction
Check stripe alignment, seams, cuffs, hems, zips, pockets and applied badges. Expectations should match the intended use: a technical sports top and an Originals sweatshirt may be constructed very differently.
What changes on pre-owned adidas clothing
Second-hand sportswear may have softened fabric, faded prints, worn labels, pilling or repaired seams. These are normal condition variables. The authenticity assessment should focus on whether the underlying branding and construction make sense for the product.
Red flags that deserve a closer look
- A product code that corresponds with an unrelated item.
- Several pieces of branding with visibly poor proportions or spelling.
- Care information that conflicts with the garment’s material or construction.
- Stripe, seam or badge placement that is inconsistent across the piece.
Treat these as reasons to check more closely rather than as single automatic tests.
Buying pre-loved adidas clothing
When shopping pre-owned, look at the actual garment rather than stock imagery. Check branding, labels, cuffs, hems, zips and any printed areas, then compare the measurements with clothing you already own. Older sizing and repeated washing can affect fit.

FAQs
Can an adidas product code confirm authenticity?
It is useful supporting evidence, but copied or incorrect codes exist and the complete garment still needs to be checked.
Does every genuine adidas item use the same logo?
No. Logo use varies between ranges, product types and production periods.
Is a cracked adidas print automatically fake?
No. Genuine older prints can crack or fade through washing and normal wear.
