How to Authenticate Adidas Football Kits
Complete guide to verifying authentic Adidas football shirts. Learn to decode product codes, understand QR labels, and spot fake kits.
Adidas is one of the most iconic football kit manufacturers, sponsoring clubs like Real Madrid, Bayern Munich, and Manchester United. Unfortunately, their popularity makes them a prime target for counterfeiters.
This guide will teach you how to authenticate any modern Adidas football kit using labels, codes, and visual details.
The Product Code Label
The most reliable starting point for authenticating an Adidas kit is the product code label, usually found sewn into the neck or shoulder area. On older shirts (pre-2010), this label may be on the left side seam.
Note
This labeling system was introduced around 2000. Kits produced before that period may not have a product code label at all—this is normal for vintage items.
Understanding the Product Code
Adidas product codes are typically 6-character alphanumeric strings. Recent codes usually start with 1-2 letters followed by 4-5 numbers. Older kits may use 6-digit numeric codes.
Example Adidas Product Code
IS7462 IS Product line prefix 7462 Unique identifier Common prefix letters include:
- IS — Standard range
- CW — Club/World range
- GM — Game range
- HK — Specific collections
⚠️ CW1526: The Trending Fake Code
CW1526 is one of the most commonly misused product codes by counterfeiters. This code is legitimate ONLY for the Colombia 2018 Home/Away kit.
If you see CW1526 on ANY of these kits, it’s almost certainly fake:
- Manchester United
- Juventus
- Bayern Munich
- Arsenal
- Real Madrid
- Any kit other than Colombia 2018
Counterfeiters reuse this code because it’s from a popular World Cup kit. Always cross-reference the product code with the actual team on the shirt.
Early Label Versions
Labels from 1999-2002 may look slightly different in format but contain the same essential information. This alone is not a sign the kit is fake—it’s just part of Adidas’s labeling evolution.
The Production Code
The production code indicates when the kit was manufactured. Look for a date format like 02/10 on the label, which means February 2010.
Production Date
02/10 02 Month (February) 10 Year (2010) Date Mismatch = Red Flag
If a kit claims to be from the 2023/24 season but has a production code from 2019, it’s almost certainly fake. Counterfeiters often reuse old labels.
The QR/Data Matrix Code
Modern Adidas labels feature a Data Matrix code (similar to a QR code) on the back of the product label. This is used for internal logistics and product tracking.
Note
The Data Matrix encodes information like style code, manufacturing batch, and factory origin. It’s readable by specialized systems used by Adidas and authorized resellers—not by standard QR code apps.
Template Kits
When you see two product codes on an Adidas swing tag, it usually means the shirt is a custom design based on a standard template. This is common for:
- Smaller clubs
- Limited editions
- One-off promotional kits
One code refers to the base template, while the other represents the customized version.
Sample Kits
Sample shirts may not follow standard labeling formats. Look for labels that clearly say “SAMPLE” inside. These aren’t fake—they’re pre-production prototypes created for testing or marketing.
Swing Tags
Swing tags are the cardboard tags attached to new kits, typically hanging from the sleeve or collar.
What to Examine
| Element | What to Look For |
|---|---|
| Product code | Must match internal label |
| Barcode | Clean, scannable |
| Price tag | Regional pricing if present |
| Cardstock | Proper weight and finish |
| Printing | Sharp, no bleeding |
Plastic Barbs vs. Twine
Adidas uses different attachment methods depending on the kit type:
- Plastic barbs — Standard for most retail kits
- Twine/string — Common on some premium or special edition kits
Pro Tip
The shirt type code on swing tags can help identify if it’s a replica or authentic version. Look for designations like “FAN” or “PLAYER” on the tag.
Care Labels
Adidas care labels are sewn into the side seam and contain washing instructions and manufacturing information.
Red Flags
- Spelling errors — Common in fakes
- Inconsistent fonts — Should match other Adidas labels
- Wrong symbols — Washing symbols follow international standards
- Poor print quality — Authentic labels are crisp and clear
The Neck Label
The neck label displays size information and technology branding.
Technology Designations
| Label | Meaning |
|---|---|
| AEROREADY | Standard moisture management |
| HEAT.RDY | Advanced heat management |
| COLD.RDY | Cold weather technology |
| Authentic | Player-spec construction |
Manufacturing Countries
Authentic Adidas shirts are manufactured in:
- Thailand
- Indonesia
- Vietnam
- Cambodia
- Turkey
- China (some legitimate production)
Note
Country of manufacture alone doesn’t determine authenticity. Always check multiple factors together.
Security Tags
Modern Adidas kits include security tags for authenticity verification.
Design Details
- Usually features Adidas logo
- Contains alphanumeric code
- Consistent placement across same product line
Timeline
| Period | Security Features |
|---|---|
| Pre-2015 | Minimal or no security tags |
| 2015-2020 | Introduction of fabric tags |
| 2020+ | Enhanced security with additional codes |
Notable Exceptions
Some legitimate player-issue or sample kits may have different or missing security tags. Context matters.
Logos and Crests
The Adidas logo and club crest are key visual authentication points.
The Adidas Logo
Adidas uses different logo variants:
- Three Stripes — On shoulders and sides
- Trefoil — Heritage/retro designs
- Performance logo — Modern training gear
Key checks:
- Even spacing between stripes
- Consistent thickness
- Clean edges (no fraying)
- Accurate placement
Club Crests
Authentic crests feature:
- Tight, consistent stitching
- Accurate colors — No obvious shade differences
- Sharp details — Fine lines are actually fine
- Proper sizing — Measured against official specs
RN56323 and CA40312
These regulatory codes appear on Adidas labels.
What They Mean
- RN56323 — Adidas’s U.S. Federal Trade Commission registration
- CA40312 — Canadian import identification
Important
These are NOT unique identifiers. Every Adidas product uses the same RN and CA numbers. Their presence confirms Adidas manufactured the item, but counterfeiters commonly copy them.
