Free PSA Cert Lookup
Verify any PSA slab — free
Paste a PSA cert number to confirm the card is real, see the official grade, and view PSA's own images.
A matching cert number confirms a PSA record exists. It does not authenticate the card or holder in front of you: counterfeit slabs reuse genuine numbers, so compare the card, grade and PSA's images with the slab itself.

How it works
Three steps to verify any PSA slab
Step 1
Find the cert number
Look at the bottom of the PSA label, below the barcode. It's an 8–10 digit number.
Step 2
Paste it above
Drop the number into the field and hit Verify now. Results come back in about a second.
Step 3
Review PSA's official record
See the grade, card name, set, year, population data, and PSA's own scans — straight from PSA's API.

What a verified slab looks like
When the cert matches, you get the full PSA record — grade, card identity, population context, and PSA's own scanned images. It confirms the record exists; only comparing that record with the slab in your hand can tell you it is genuine.
