Verify an Upper Deck Authenticated (UDA) hologram, COA or authentication number for signed sports and entertainment memorabilia. Upper Deck is a leading sports and entertainment trading card and collectibles company, and UDA is its signed memorabilia program built around witnessed signings, serialized hologram numbers and Certificates of Authenticity. Enter the number, scan the QR or upload a photo, and CheckCOA checks the provider record when available and screens it against our Fraud Base of known fake, stolen, reused or compromised numbers, with 25+ authentication providers supported. Older UDA items are not always in the online database, so no result does not automatically mean fake. CheckCOA is independent and not the official Upper Deck site.
Checking more than Upper Deck? CheckCOA also verifies PSA/DNA, Beckett BAS, JSA, Fanatics, Panini, SGC Authentic and 20+ more autograph and grading providers in one place.
Enter the UDA hologram, COA or authentication number from the item, sticker or Certificate of Authenticity. Scan the QR, upload a photo or type it in. Checking a graded card or slab instead? Use the grading provider shown on the label, such as PSA, Beckett, CGC, SGC or TAG.

Upper Deck is a leading sports and entertainment trading card and collectibles company. Upper Deck Authenticated, or UDA, is its signed memorabilia program. UDA items are tied to controlled or witnessed signing sessions and identified with serialized hologram numbers, Certificates of Authenticity and authentication numbers. Collectors use UDA hologram and COA lookup to compare the item, the certificate and the provider record before buying or selling signed memorabilia.
A UDA hologram number is a serialized identifier connected to an authenticated signed item. In most cases the number appears on a tamper-evident hologram sticker, on the Certificate of Authenticity, or on both. The number on the item should match the number on the COA. If the item and certificate show different numbers, or the hologram looks altered, copied or poorly printed, the listing deserves closer review.
Look for a clear, serialized UDA hologram or sticker on the item or its paperwork.
The hologram number and the COA number should match when both are present.
Compare the signer, item, photos, certificate details and seller history before buying.
Some older Upper Deck Authenticated items do not appear in current online lookup results. Upper Deck did not retroactively digitize older products, so many legitimate UDA items more than about twenty years old simply are not in the online database. This is common with pre-2000s memorabilia and with older Michael Jordan items, including Flight Camp autographs whose certificates list only the camp and year. A missing result does not prove that a UDA item is fake, but it means you should verify the hologram, COA, photos, seller history and provenance more carefully.
If a UDA number returns no result, recheck the digits first. Then compare the hologram and COA, ask for clearer photos, and consider contacting Upper Deck or the seller for additional documentation. No result is not proof of a fake, and a match is not proof of authenticity.
A standard UDA lookup can help confirm whether a certificate or hologram record is available. CheckCOA brings that lookup into an all-in-one verification workflow and adds a safety layer: Fraud Alert checks against known fake COAs, counterfeit certificates, copied holograms, reused numbers and compromised records. This helps collectors spot already-reported risks before buying expensive signed memorabilia.
High-value signed memorabilia attracts counterfeiters. Fake UDA holograms, copied certificate numbers and reused COAs appear on marketplace listings, especially for popular athletes and expensive autographed items. A certificate number can even match a real record but still be misused on a different item. CheckCOA screens every UDA COA lookup against a growing database of known fake, stolen, reused and compromised certificate numbers to help reduce that risk.
A clean result is not a guarantee of authenticity. New fakes appear every day, so always compare the autograph, item, hologram, COA, photos, seller history and provenance before buying.
Use this Upper Deck UDA cert lookup for signed sports and entertainment memorabilia with a UDA certificate, hologram or authentication number. It is especially useful when checking marketplace listings, private sales, collection records or high-value autographs before purchase.
Checking a different autograph COA? CheckCOA also supports PSA, Beckett BAS, JSA, Fanatics, Panini, ACOA, SWAU, TRISTAR, MLB Authentication and more.
Check UDA provider records when available, compare the hologram and COA, and screen the number with free Fraud Alert protection.
Verify UDA CertUse these practical checks to choose the right lookup, read the result and decide when the item needs closer review.
Upper Deck Authenticated, or UDA, is Upper Deck's signed memorabilia program. UDA items are associated with witnessed signings, serialized hologram numbers and Certificates of Authenticity. Upper Deck itself is a leading sports and entertainment trading card and collectibles company.
The number appears on the tamper-evident hologram sticker, the Certificate of Authenticity, or both. When an item hologram and a COA are both present, the two numbers should match. Enter the number exactly as shown.
Upper Deck never fully digitized its older products, so many legitimate UDA items more than about twenty years old do not appear in the online database. A no-result can also be a typo or a record that is not available from the provider source. It does not automatically mean the item is fake, but it should be reviewed more carefully.
Yes. Many older Michael Jordan items, including Flight Camp autographs whose certificates list only the camp and year, are not in the current online database, and Jordan is the most forged autograph in the hobby. For older Jordan memorabilia, compare the hologram, COA, photos and provenance, and consider an expert. For Michael Jordan specifically you can also use the GOAT Authentics cert lookup.
Yes. Counterfeiters can copy a genuine hologram or certificate number and use it on an unrelated item. That is why you should compare the lookup result with the actual item, COA, hologram and seller photos, and use reverse-image search when photos look recycled.
No. CheckCOA is an independent verification tool. It helps you check provider records when available, organizes your checks in one place, and adds Fraud Alert checks against known fake, stolen, reused or compromised numbers.
Yes. CheckCOA supports QR scan, camera scan, image OCR and manual entry. One verification works the same way no matter how you enter the certificate number. Review the detected number before verifying.
Compare the hologram number, COA number, item description, signature, photos, seller history and provenance. Be especially careful with expensive signed memorabilia and with listings that have unclear photos or unusually low prices.
Yes. Every UpperDeck 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.
