How do I look up a CGC comic cert?

Enter the certification number from the CGC label — verification opens CGC's official cert page for that exact book, with grade, page quality and grader notes.

Where is the cert number on a CGC slab?

On the label, above the barcode: a 10-digit number formatted like 1234567890 (older slabs use 7 digits plus a suffix). Newer slabs also carry a QR code resolving to the same record.

What if the CGC cert doesn't match the book?

Don't buy it — mismatches mean a reprinted or transplanted label. Report the listing; counterfeit CGC holders cluster around major keys.

Red flags when verifying a CGC slab

The cert returns a different title, issue or grade than the slab in front of you.
No record for a modern-format number — counterfeit until proven otherwise.
The inner well looks tampered or re-sealed; CGC cases are tamper-evident.
Keys at too-good prices — fakes cluster around Hulk 181, ASM 300, X-Men 1 and friends. Verify before money moves.

Cert checks prove the slab, not the price. Whether the book is worth its ask — or worth grading at all — is the calculator's job.
