Clearing a certificate means publishing your photo as the verified item for that number, so a claim is tied to an account. Reporting a suspected fake does not require one.

Claiming a genuine item - common questions

Why do I have to sign in to submit a claim?

Approving a claim clears the certificate number and publishes your photo as the verified item anyone will see when they check it. That is a public statement made on your behalf, so it is tied to an account. Reporting a suspected fake does not require one.

Why is there no "other" reason I can write in?

CheckCOA records what an authenticator or an auction house already put in writing; we do not authenticate items ourselves. That is why each reason names a document somebody else issued. "I own it and it looks genuine to me" is a request for a free authentication, which is not something we can act on.

What counts as proof?

A full letter of authenticity with its own certificate number, the original invoice or receipt from the authenticator, a written opinion from a recognised expert, or an auction invoice with the lot number. A verbal opinion, or a photo of the item on its own, is not enough on its own to clear a number.

Which photos should I upload?

Photograph the item itself and the document behind your claim. The photo of your item matters twice over: it is what the reviewer compares against the provider record, and if we clear the number it is what buyers see on the result instead of an empty provider record.

What happens if my claim is approved?

The certificate stops showing the flag, and your photo appears on the result as the verified genuine item for that number. We email you when it is done.

What happens if my claim is declined?

The certificate stays flagged and we email you the reason. Nothing is permanent: if the item is later upgraded to a full LOA, or an authenticator puts an opinion in writing, send it over and we will look at the number again.

My certificate is fine but the seller of a similar item is faking it. What then?

That is a counterfeit report, not a claim. Use the Report a Fake page, and include the listing link so we can look at the item ourselves.
