Verify COA/LOA and grading certificates from trusted providers in one place.
CheckCOA is the only tool covering both autograph COAs and graded card certificates — PSA, Beckett, GOAT, CGC, Upper Deck, Fanatics, SWAU, Tristar, and 15+ more. Every check is cross-referenced against our growing Fraud Alert database of compromised, fake, stolen and reused certificates.

Camera, QR code, OCR, clipboard paste, or manual entry — verify any cert in seconds, however you prefer.
Every scan checks against 25,000+ known fake, stolen, reused and compromised certificates. Fake slabs, stolen stickers, duplicate certs — flagged instantly, no extra steps.
PSA, Beckett, SGC, CGC, Upper Deck, SWAU, Tristar and more — autograph COAs and graded cards, all supported. No switching between sites.
Every check is saved automatically. Search by name, cert number, provider or date — organize into collections or a wishlist.
CheckCOA is not affiliated with PSA, Beckett, CGC, or other providers. We do not authenticate items—we only retrieve and display provider records.
