Quick answer

A certificate of authenticity is only trustworthy if you can confirm it with its issuer yourself and it matches the item. Find the issuer's official website on your own, look up the certificate number there, and compare the record's details and photos with the item. Treat a certificate as unreliable if the issuer cannot be found, the number does not open a record, the QR code leads to another website, or the details do not match.

Fake certificates are cheap to make and easy to believe, and a certificate can be real and still belong to a different item. This guide covers the warning signs, a step-by-step check you can do on your own phone, and what to do when a certificate does not check out.

Why certificates are easy to fake

A printed certificate is a document, not part of the item. Templates, seals, holograms and signatures can all be reproduced, and a convincing design says nothing about whether anyone examined the item.

This is not a new problem. Describing its Operation Bullpen investigation into forged sports memorabilia in 2003, the FBI said that many forged items came with certificates of authenticity that were forged as well.

Genuine documents are misused too. Testimony in Chanel's lawsuit against the reseller What Goes Around Comes Around described the theft of about 30,000 Chanel authenticity cards, and The Fashion Law reported that counterfeiters had used stolen cards. Codes are copied as well: Certilogo, which runs code checks for Stone Island, says a tag with a code does not necessarily mean the product is authentic.

Warning signs of a fake or unreliable certificate

Any one of these is a reason to stop and check further before you pay:

  • No named issuer, or an issuer you cannot find independently online.
  • No unique certificate number, or a number that does not open a record on the issuer's own website.
  • A QR code or link that opens a lookalike domain, a shortened link, or a page asking for payment or login details.
  • Generic wording such as 100% genuine guaranteed, with no item description, photos, date or result.
  • A certificate written by the seller, or one presented as an official document from a brand that does not issue them. Christian Louboutin, for example, says neither its boutiques nor its online boutique issue authenticity certificates, and Tiffany says it does not offer an authentication program.
  • Details that do not match the item: brand, model, color, size, serial number, date code or condition.
  • Only a screenshot, photo or forwarded PDF, with no way to open the original record.
  • A seller who will not let you verify the certificate before you pay.

How to verify a certificate of authenticity, step by step

Do the check yourself, on your own device:

  • Identify the issuer named on the certificate.
  • Find the issuer's official website independently, by searching for it. Do not use the link or QR code on the certificate for this step.
  • Look up the certificate number on that website, or scan the QR code and confirm that the address bar shows the issuer's real domain.
  • Compare the record with the item: brand, model, serial number or date code, color, condition and photos.
  • Where the record has photos, check distinctive marks such as scratches, wear or stitching that a copied certificate could not predict.
  • Contact the issuer if anything is unclear, and keep a copy of the record with your purchase.
  • For a Vereev certificate, enter its E-Result code at vereev-ai.com/verify. The checker warns you when a pasted link is not from Vereev.

When a real certificate belongs to another item

A certificate that checks out still only describes the item that was examined. Genuine cards and certificates can be separated from that item, and a seller can pair a valid certificate with a different or counterfeit piece.

That is why the record's photos and identifying details matter more than the certificate's design. A record with no photos and no unique identifiers cannot tell you much about the item in front of you.

Brand cards, chips and digital certificates

Brand systems change over time, and knowing them helps you spot a document that should not exist. Resellers report that from 2021 Chanel replaced the serial sticker and authenticity card in its bags with a metal plate holding a microchip, so a recent Chanel bag without a card is normal. Chanel itself points buyers to its boutiques and official website.

Some brands now issue digital certificates that open from an NFC tag in the product, such as Prada's Digital Certificate of Ownership and Rimowa's Ownership Certificate. Others do not verify items at all: Hermès says it does not verify items acquired outside its own channels. A certificate presented as an official document from such a brand should be treated with caution.

What to do if a certificate does not check out

A failed certificate does not prove that the item is fake, but it removes the evidence the seller offered. Decide on the item itself:

  • Do not pay, or pause the payment if your platform allows it.
  • Ask the seller for the original record from the issuer and clear photos of the item's own markings.
  • Get the item itself authenticated, using clear photos of the whole item and its details.
  • If you have already paid, contact the marketplace or your payment provider promptly, because dispute windows are limited.

Common questions

What readers ask about this topic

How can I check if a certificate of authenticity is real?

Find the issuer's official website yourself, look up the certificate number there, and compare the record, including any photos, with the item. A certificate you cannot confirm with its issuer is not evidence.

Can a fake item come with a real certificate?

Yes. A genuine certificate or card can be separated from the item it came with and paired with a different one, so the record's details and photos must match the item in front of you.

Is a certificate with a hologram or QR code more reliable?

Not by itself. Holograms can be copied, and a QR code can open any website. What matters is whether the record opens on the issuer's real domain and matches the item.

What if the seller only sends a screenshot of the certificate?

Ask for the certificate number and check it yourself on the issuer's website. A screenshot or forwarded PDF can be edited or can belong to another item.

How do I check a Vereev certificate?

Enter the E-Result code printed on the certificate at vereev-ai.com/verify, or scan its QR code. The official record shows the result, date and reviewed photos, so you can compare them with the item.
