Box Logo hoodies are what replica makers chase hardest, and today's fakes match the color and fabric. A Supreme authenticity check catches them on the box logo letters, neck tag spacing, wash tag stitching and drawcords. We know of no serial number or official lookup from Supreme, and collaborations with The North Face, Louis Vuitton and others are authenticated here too.

What we check on Supreme
How to tell a real Supreme from a fake
The box logo letters come first on Supreme: even spacing with no letters touching, an oval p and stretched e shapes. The neck tag, the wash tag and the fabric then have to match the season.
01
Box logo letters
Even spacing with no letters touching, an oval p, stretched e shapes, a final e on the baseline and letters that are not too thick.
02
Neck tag
Font and spacing, and the gap and alignment between the Supreme tag and the Made in tag.
03
Wash tag
A single straight line of stitching with a small flap of tag above it, and sharp text.
04
Box logo embroidery
Thread density, color and placement of the logo relative to the pocket.
05
Drawcords and hems
Flat drawcords, cuff and hem construction on hoodies.
06
Fabric
Weight and hand of the fleece or jersey for the season.
07

We know of no Supreme serial number or official lookup. The RN number on a wash tag is a US textile registration that identifies the company, not the item, and fakes print it too, so it cannot prove a piece is real. A professional authenticator checks the logo, the tags and the construction instead.
No, not by itself. Many Box Logo hoodies carry a Made in Canada tag, many tees say Made in U.S.A., and some accessories and collaborations are made in other countries. So we check the tag against the item and the season, not against one country.
Look at the letters first: a little space between each, an oval p, stretched e shapes and no letter too thick. Then check the gap and alignment between the Supreme tag and the Made in Canada tag, and the single straight stitch on the wash tag. Our authenticators compare each detail with verified references.
Yes. Collaborations with The North Face, Louis Vuitton and other brands are checked on this page from photos of the co-branded labels, the hardware and the construction.
Yes. Ask the seller for photos of the box logo up close, the neck tags front and back, the wash tag and the drawcords, then upload them before you pay. A professional authenticator returns a verdict, Authentic or Fake.
Better copies now match the color and the fabric, so we judge the details they still miss: letter shapes in the box logo, tag spacing, wash tag stitching and drawcords, against verified references for that season. If the photos are not enough to decide, we ask for more.
For the most accurate and quick authentication process, we advise you to upload clear photos of the areas visible when clicking 'Upload photos' on this page. We quickly determine if the uploaded photo meets our criteria. If your photos do not meet the criteria, you will receive a request for more and/or clearer photos. Check out Photo Instructions to find clear examples for each detail.
