If you are trying to work out whether a New Balance football shirt is real, one of the best places to start is the product code. Most genuine New Balance football shirts have a unique New Balance code printed on the internal wash label, and this code can often help you match the shirt to the correct team, season and kit type.
At Football Shirt Kingdom, product codes are one of the main details we use when identifying authentic shirts. In this guide, we will show you where to find a New Balance football shirt product code, how to search it, what it should look like, and the mistakes to watch out for.
If you want to check a code quickly, you can also use our Football Shirt Product Code Authenticator.
Where is the New Balance product code on a football shirt?
On most New Balance football shirts, the product code is usually found on the wash tags.
Example 1 - Celtic 2016 Third Shirt - MT630112
On the underside of the wash tag - 2 Letters followed by 6 Digits
Example 2 - Porto 2024 Away Shirt - MT230377
On the top of the wash tag - 2 Letters followed by 6 Digits
What to look out for
It is usually printed clearly and neatly. If the label is badly printed, missing, inconsistent with the rest of the shirt, or shows a code format that does not match normal New Balance patterns, that can be a warning sign.
Step-by-step: how to check if a New Balance shirt code is real
1. Find the code on the wash label
Look inside the shirt for the small New Balance internal label and locate the product code.
2. Search the exact code online or on our Product Code Authenticator
Type the exact code into Google or our authenticator.
3. Check whether the results match the shirt
A genuine code should usually bring back the same or very closely related shirt depending on the code. Compare:
-
team
-
colour
-
season
-
kit type
-
Stadium / Authentic Version
Example on google:
If the code brings up a completely different product, that is a red flag.
4. Compare the shirt details
Even if the code looks right, also compare the shirt itself:
-
badge style
-
sponsor
-
material and pattern
-
New Balance logo style
-
wash tags if present
5. Use the code as one check, not the only check
A product code is one of the strongest indicators, but it should be used alongside the shirt’s overall quality and design details.
Why product codes matter when buying football shirts online
When buying vintage, retro or modern football shirts online, the product code can help you buy with more confidence. A clear code lets you:
-
verify that the shirt matches the listing
-
confirm the likely season and model
-
spot obvious mismatches
-
compare multiple shirts more accurately
At Football Shirt Kingdom, we include product codes where available to help collectors and buyers make more informed decisions.
