CheckCOA is the all-in-one, free PSA/DNA cert lookup: verify an autograph authentication or COA number, and switch to PSA graded cards, comics or video games in the same place, with every result screened against our Fraud Base of known fake, stolen, reused or compromised numbers and 25+ authentication providers supported. Enter the number from the PSA/DNA sticker, COA or LOA, or scan a QR or photo when available, then compare the provider record with the signed item. Checking a PSA-graded card, comic or video game instead? Choose the matching PSA lookup above.
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: graded cards, PSA/DNA autographs, 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.
A standard provider lookup can confirm whether a PSA/DNA certificate record is available. CheckCOA adds an all-in-one workflow with QR scan, camera scan, image OCR, manual entry, saved history and Collections, plus Fraud Alert checks against known fake, stolen, reused or compromised certificate numbers.
A genuine PSA/DNA number or an image of real paperwork can be copied and offered with a different autograph. That is why the lookup is one part of a purchase check, not a final authenticity verdict. CheckCOA screens every PSA/DNA cert lookup against a growing database of more than 25,000 reported fake, stolen, reused and compromised certificate numbers to help collectors avoid already-reported risks.
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 cert lookup before you buy or sell signed memorabilia. Compare the authentication number, sticker, LOA and returned record with the item in front of you, then review any Fraud Alert warnings for known fake or reused certificate numbers.
Check the provider record when available and screen the number with free Fraud Alert protection.
Use the authentication number as a starting point, then compare the returned record with the sticker, LOA and signed item in front of you.
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. If the item in front of you is a graded slab and you want to confirm the card grade, use the PSA Graded Cards lookup.
Check the PSA/DNA sticker attached to the item and the matching Letter or Certificate of Authenticity. The authentication number should be printed clearly on both when both were issued. Enter the letters and digits exactly as shown, without adding words such as PSA or COA. If you are checking a marketplace listing, ask the seller for separate, sharp close-ups of the sticker, the full LOA and the signed item; a cropped number alone does not let you confirm that the paperwork belongs to that object.
Compare every field returned by the provider source with the physical item and its paperwork. The authentication number must match character for character. When the record includes a signer, item type or description, those details should also agree with the autograph and LOA. Check that the same number has not been shown on unrelated items in the seller’s photos. A database match confirms that a record exists for the number; it does not prove that the sticker, LOA or autograph in front of you is the original one connected to that record.
First re-read easily confused characters and try the number without spaces or punctuation. Confirm that you selected PSA/DNA rather than PSA graded cards. Older records, recently issued certificates and temporary provider outages may not return complete data immediately. If repeated attempts still produce no result, do not treat the seller’s screenshot as a substitute. Ask for clear current photos of the sticker, LOA and item, and contact the provider when the purchase value justifies additional confirmation.
Yes. A clear photo can be scanned with OCR, but you should review the detected number before verifying because glare, small print and similar characters can create mistakes. A QR code is only an input shortcut: it does not make the physical item authentic by itself. After the scan, compare the displayed authentication number and returned details with the sticker or LOA. If a QR points to a graded-card record instead, switch to the graded-card lookup rather than forcing the result into the autograph database.
Yes. A real number or an image of genuine paperwork can be copied and offered with a different autograph. That is why the lookup is one part of a purchase check, not a final authenticity verdict. Compare the exact item description, sticker placement, printing quality, LOA and seller history; use reverse-image search when photos look recycled. CheckCOA also screens the number against reported Fraud Alerts, but the absence of an alert means only that no matching report was found at the time of the check.
Yes. Verifying a PSA/DNA authentication or COA number on CheckCOA is free and needs no account. Enter or scan the number to check the provider record when available and screen it against Fraud Alerts for known fake, stolen, reused or compromised numbers.
A signed card in a sealed PSA slab is verified through the graded-card database, not the PSA/DNA autograph database, even though it carries an autograph. Use the Cards lookup above for the slab certification number. Use this PSA/DNA lookup for a loose signed item or a separate autograph authentication with its own sticker, COA or LOA.
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.
