Issey Miyake's design studio was founded in 1970, and today its Bao Bao bags, Pleats Please and Homme Plissé are the pieces people most often ask about. Bao Bao's triangle panels are widely imitated, and in 2019 the Tokyo District Court ruled for Issey Miyake against a maker of lookalike bags. We know of no public Issey Miyake serial number check. The product code on the tag identifies the model, not the individual piece, and valid codes are copied.
Send photos of your Issey Miyake bag or garment and a professional authenticator checks the panels or pleats, the tags and product code, the interior label, the hardware and the construction against verified references for that line. Each line has its own labels, so the first step is matching your piece to the right one.

On Bao Bao, the triangle panels and how they flex on the backing come first, then the interior label and the product code.

Interior label
Stamp or patch font, spacing, depth and placement.
03

Whether the full code fits the model, color and material, and how it is printed.

05
Handles and strap
Material, thickness and how the handles are attached.
Clothing and streetwear

No public one that we know of. The product code on the tag identifies the model, not your individual piece, and counterfeiters copy valid codes. The code is one checkpoint, never proof, so we check it together with the panels or pleats, the labels and the construction.
Look at how even and well aligned the triangle panels are and how the bag flexes on its mesh backing. A triangle surface that does not move like a real Bao Bao is a warning sign. Then check the interior label and the zip, and upload photos of each for a comparison with verified references.
It is a product code for the model, shared by every piece of that style and color, not a serial for yours. Searching the full code shows whether it fits the model you have, but fakes copy valid codes, so it is one checkpoint and never proof on its own.
Yes. Each line has its own labels and codes, so we check your piece against references for that line, along with the pleats and the fabric.
Ask the seller for photos of the whole piece, the panels or pleats up close, the interior label, every tag with its code and the zip. Upload them before you pay, whether it is listed on Vinted, eBay or another resale site, and you get a verdict, Authentic or Fake.
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.
We provide a range of authentication response times to suit your needs, with options including 12 hours, 6 hours, 2 hours, and 30 minutes.
