CheckCOA is the all-in-one, free PSA/DNA cert lookup: verify an autograph authentication or COA number with no account required, and reach PSA graded cards, comics or video games from the same place. Enter or scan the number from the PSA/DNA sticker, COA or LOA to check the provider record for autograph, signer and item details. CheckCOA automatically checks the same authentication number against a second, independent source: Fraud Alert records for known fake, stolen, reused or compromised numbers. Both results appear together, with screenshots, listing references, seller history or investigation evidence shown when available. Use this page for signed items; choose the matching PSA lookup above for a graded card, comic, magazine or video game.
Checking more than PSA/DNA? CheckCOA also verifies Beckett BAS, JSA, SGC Authentic, Upper Deck, Fanatics and 20+ more autograph and grading providers in one place.
Choose the PSA category that matches the item: PSA/DNA autographs, graded cards, comics and magazines, or video games.
Enter the PSA/DNA authentication number from the sticker, COA or LOA. Use this page for signed items and autographs; for a PSA-graded card, comic or video game, choose its category above.
PSA/DNA is the autograph-authentication service used for signed photos, jerseys, balls, cards and other memorabilia. Its authentication number belongs in this lookup. A PSA-graded card in a sealed slab uses a different certification database, even when the card also carries an autograph, so match the branch to the item before you search.
Signed photos, jerseys, balls, cards and other memorabilia authenticated by PSA/DNA, with a sticker, COA or LOA number.
A PSA-graded card in a sealed slab, even one that also carries an autograph. Switch to the Cards lookup above.
Check the item. A PSA/DNA sticker, LOA or COA belongs here; a graded slab with a certification number belongs in the Cards lookup.
Enter or scan one PSA/DNA authentication number. CheckCOA retrieves the available provider record and automatically checks its independent Fraud Alert database. The autograph record and any alert are shown together, so a normal certificate lookup stays the main task while reported risk information is added as a safety layer.
Verify the authentication number, compare the returned signer and item details with the sticker, COA or LOA, and save the result to History or Collections when you want a record of the check. Before buying or selling, keep the lookup with current item photos and review any Fraud Alert that appears.
A genuine PSA/DNA number or an image of real paperwork can be copied and offered with another autograph. The independent Fraud Alert check can identify previously reported reuse, but it cannot authenticate the physical signature in front of you.
A clean result is not a guarantee of authenticity. New fake autographs and copied certificates appear every day, so always compare the signature, sticker, LOA, seller history and provenance before buying.
Use this PSA/DNA lookup for autograph authentication numbers on signed memorabilia, stickers, COAs and LOAs. A certification number on a PSA-graded card slab belongs in Cards, while graded comics, magazines and games have their own PSA categories.
View the available PSA/DNA record and the independent CheckCOA Fraud Alert result together.
Use the authentication number as a starting point, then compare the returned record with the sticker, LOA and signed item in front of you.
When the provider source returns a record, the result can include the authentication number, signer, item type, description and COA or LOA details. Compare every available field with the signed item and paperwork in front of you.
CheckCOA is an independent aggregator, not PSA. It shows available PSA/DNA provider data and automatically adds a separate Fraud Alert result for known fake, stolen, reused or compromised numbers. It also supports manual entry, camera and image OCR, History and eligible Collections.
Yes. One submitted authentication number is checked against the available PSA/DNA provider source and CheckCOA’s independent Fraud Alert records. Both results are displayed together; CheckCOA does not claim that the two sources are the same database.
Yes. A genuine number, sticker image or piece of paperwork can be copied and paired with another autograph. A provider-record match confirms data for the number, not the authenticity of the physical signature, sticker or LOA in front of you.
When it is available, an alert may include screenshots, marketplace listing references, seller history, community reports or investigation evidence. Some reports have less supporting material, so evidence is shown only when it exists.
No. A clean result means no matching Fraud Alert was found at the time of the check; it does not authenticate the physical autograph. Compare the signature, sticker, item description, COA or LOA, seller history and provenance before buying.
Use PSA/DNA for signed memorabilia and autograph authentication numbers on stickers, COAs or LOAs. A PSA-graded card slab belongs in the PSA Graded Cards lookup.
Yes. Every PSA 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.
All-in-one cert lookup across PSA, Beckett, CGC, Upper Deck, BGS and 20+ more. Every scan is auto-checked against our growing Fraud Alert database - 25,000+ known fake, stolen, reused & compromised certificates.
