JSA Autograph COA Lookup (Verify Certificate Number)

Begin by looking up the full alphanumeric number from the JSA sticker or LOA, then compare the returned record with the item itself. The signer and item description should make sense for the autograph being sold, and the sticker number should agree with the accompanying paperwork when both are present. Inspect print quality, alterations and sticker placement, and ask for uncropped photos. A database match is useful evidence that the number exists, but it cannot show that the physical sticker and autograph are the original pair.

The number is printed on the JSA authentication sticker and, for items issued with a Letter of Authenticity, on the LOA as well. Enter all letters and digits exactly as shown. Do not copy a marketplace title or seller-supplied transcription without checking the photo, because similar characters are easily confused. If the listing includes only the number, request one close-up that shows the sticker clearly and another that shows the sticker in context on the signed item.

Some newer JSA labels use a short QR destination that redirects to the provider record. Scanning that code is a convenient way to capture the certificate number, but the redirect itself is not an authenticity test. CheckCOA resolves supported QR destinations and uses the resulting identifier for the lookup. After the record appears, confirm that the certificate number, signer and item description match what you can see. If the QR is unreadable or points somewhere unexpected, enter the printed number manually and avoid non-provider login or payment pages.

The certificate number must match exactly. When the source supplies a signer, item type, description or authentication details, compare each field with the autograph, sticker and LOA. Pay attention to generic descriptions: a record that says only “signed item” provides less confirmation than a specific player and object. Check whether the seller has reused the same certificate image in multiple listings, and compare handwriting or placement only as supporting context. Any material conflict between the provider record and the physical item requires clarification before purchase.

First check the prefix, letter shapes and digits, then retry without spaces. Make sure the number belongs to JSA rather than another authenticator. Newly issued or older records may have limited availability, and provider services can be temporarily unavailable. A damaged QR can fail even when the printed number is correct, so manual entry is the best second attempt. If the number still has no record, request the complete sticker and LOA images and contact the provider before relying on seller screenshots.

Be cautious when the sticker number is blurred, cropped or different from the LOA; when printing appears altered; when the returned signer or item description conflicts with the listing; or when the seller refuses current close-ups. Search for duplicate photos and review seller history. A genuine certificate number can be copied onto counterfeit paperwork, so the lookup should be combined with physical details and provenance. CheckCOA’s Fraud Alert screen can identify reported compromised numbers, but an unreported misuse will not automatically appear.

Yes. Every JSA lookup is screened against CheckCOA's Fraud Alert database of 25,000+ known fake, stolen, reused and compromised certificate records. This helps flag known fake COAs, counterfeit slabs, reused serial numbers and other reported risk signals, but it does not replace expert authentication.
