Nike Authenticity Guide

How to approach Nike product codes, wash labels, neck label / size writing and season-specific details.

Reviewed by Revive Sports · 11 July 2026

Nike product codes

Nike codes are often found behind the washing labels or on the front tag. The code should return the correct club, season and colourway.

Separate the product code from front security numbers

Nike product codes usually include a style and colour suffix, such as IB5290-100. Front hem or security numbers are a different type of evidence and can be copied or repeated on shirts that are not genuine. Never treat the front number alone as proof.

Not genuine Nike shirt front engineered tag showing code P005828n20 — Not genuine example: front engineered tag with repeated searchable code P005828n20.

Not genuine Nike shirt neck size writing and Dri-FIT print — Use the front code with neck writing, country of manufacture and print quality checks.

Not genuine Nike shirt embroidered swoosh detail — Badge and swoosh construction should still be checked alongside the code.

Not genuine Nike tag and label examples

This red Nike example shows a weak label stack: rough black authenticity tag finishing, soft wash-label print, inconsistent small-label code details and a poor-looking small swoosh tag. Use these photos as a not genuine comparison when the labels do not match known genuine Nike construction for the shirt.

Not genuine Nike wash label and black neck tag — Wash label and black authenticity tag should be checked together.

Not genuine Nike fabric label with RN number — Not genuine example: fuzzy label print and weak label construction.

Not genuine Nike small product code label — Small product-code labels should support the exact shirt and look correctly printed.

Not genuine Nike long washing label — Long wash labels should have clear print, correct spacing and season-correct construction.

Not genuine Nike code label examples

These red Nike examples show unsupported code and label warning signs. Check the product-code label, black authenticity tag and washing labels together: the codes should support the exact shirt, the print should be clean, and the label stack should match known genuine Nike construction.

Black authentic tag and covered code examples

Not genuine Nike wash label with partly covered product code label — Not genuine example: a partly covered product-code label makes the code hard to verify against the exact shirt.

Not genuine Nike black authenticity tag showing 000564578 and 2015 — Not genuine example: black authenticity tag showing 000564578 and 2015.

Label construction
