For buyers

Scan before you buy

Buying pre-owned clothing on eBay, Poshmark, Mercari, Depop, or in person? If the item has a GradeThread Garment Passport, you can read its whole story first — every condition grade, listing, sale, and ownership handoff tied to that exact garment. It's free and takes no account.

On a phone? Just point your camera at the QR code on the item tag or listing — it opens the passport directly.

How to scan a passport

  1. 1

    Scan the tag QR code or open the passport link

    If the item carries a GradeThread passport tag or the seller shared a passport link, scan the QR with your phone camera or tap the link — it opens the item's full history instantly.

  2. 2

    Or enter the passport slug or tag code

    No QR handy? Paste the passport URL, its slug, or the printed tag code (like ABCD-EFGH-JK) into the box on gradethread.com/scan to pull up the item's passport.

  3. 3

    Read the garment's history before you buy

    The passport shows a confidence-scored timeline — every grade, listing, sale, and ownership handoff — so you can see how the item was described over time and whether the condition holds up.

  4. 4

    Buy with the history behind you

    Participants stay pseudonymous and no personal data is shown. You just get the provenance: an independent record of what this specific garment has been through.

A Garment Passport isn't tied to one marketplace — the same QR code and link open the history on eBay, Poshmark, Mercari, Depop, or for a face-to-face sale.

Why a passport matters

The whole story, not one snapshot

A passport links every grade, listing, sale, and ownership handoff to the same physical garment — so you see how it was described over time, not just one seller's word today.

Pseudonymous by design

Participants appear only as 'Seller A' or 'Buyer B'. No names, no emails, no addresses — a past owner is only ever shown if they personally chose to be.

Confidence-scored provenance

Each link in the chain is labeled with how certain it is, so you can tell a verified handoff from a probable match — and judge the history for yourself.

Just have a certificate code instead of a passport? Use verify a condition grade to check a single grade, or read how the 1.0–10.0 scale works.

Grade your item to get a passport

Frequently asked

How do I look up a garment's passport before buying?
Scan the GradeThread passport QR on the item or listing, open the seller's passport link, or paste the passport slug or printed tag code at gradethread.com/scan. The public passport shows the item's confidence-scored grade, listing, and ownership history — free and with no account.
What's the difference between a passport and a certificate?
A certificate is the grade for one inspection. A Garment Passport is the item's whole story over time — every grade, listing, sale, and ownership transfer linked to the same physical garment — so you can see provenance, not just a single snapshot.
Does looking up a passport reveal who owned the item?
No. Passports are pseudonymous by design — participants appear only as ordinal labels like 'Seller A' or 'Buyer B'. A past owner only ever appears by name if they personally opted in to be shown. No personal information is exposed.
I'm a seller — how do my items get a passport?
Grade an item with GradeThread and it gets a passport automatically. Add a physical QR tag so buyers can scan it in hand, and the item's verified history travels with it across every marketplace.
