Treat the slab as unverified and do not buy, sell, trade, or crack it until the mismatch is resolved. A matching certification number only confirms that the number exists in the grader's records; it does not prove the enclosed card is genuine or belongs with that label. A slab is the sealed plastic holder used for a graded card, while its certification number is the grader's unique record identifier. A mismatch may reflect a database error, label mistake, altered holder, or copied certification number.

What Does the Matching Certification Prove?
The lookup should identify the card associated with that certification number. Compare every listed detail with both the label and the enclosed card, not just the grade or Pokémon's name.
Check these features: Some differences are minor. A database may abbreviate a set name or omit a variant. A different Pokémon, card number, artwork, or language is a material mismatch that requires an explanation.

- First Edition, promotional, or other designation
Could It Be an Innocent Error?
Yes, but the matching number does not reveal which error occurred. The grader could have entered incorrect database information, printed the wrong label, or attached images from another submission. Older holders may also use label formats that differ from current examples.
Likewise, a lookup page may lack photographs or show limited card details. Neither situation proves fraud, but neither resolves a material mismatch. Check the grader's official lookup again by entering the number manually. A QR code or barcode on a questionable holder could direct you somewhere misleading, so do not rely on that route alone.
Check the Holder Without Opening It
Inspect the slab under bright, angled light. Look for separation along the edges, cloudy adhesive-like residue, cracks near the seams, distorted plastic, or a label that appears loose or poorly aligned. Compare the holder and label with confirmed examples from the same grading company and approximate holder generation.
Logos, fonts, holograms, and layouts can change, so one visual difference is not conclusive. Do not crack the slab to inspect the card. Opening it removes the holder from the grader's control, can damage the card, and may weaken a return or payment dispute.
Preserve Evidence and Contact the Right Parties
Photograph the front, back, certification label, holder edges, and the mismatch visible on the lookup page. Save the listing, seller messages, receipt, payment record, and packaging. Contact the grading company through the contact information on its official website.
Ask whether the certification belongs to the enclosed card and provide clear photographs. Do not assume the company will authenticate the slab from images alone; it may require an in-person review or submission. If the purchase is recent, notify the seller or marketplace promptly. Return and dispute deadlines vary, so preserve the original condition and follow the platform's instructions before shipping anything.
What Should You Do With the Card?
If you have not bought it, pause the transaction until the grader confirms the card-holder combination. A discount does not compensate for an uncertain identity, grade, or resale status. If you already own it, keep it separate from verified inventory and describe it as unverified.
Do not list it using the matching certification record as proof when the physical card contradicts that record. If the grader confirms a clerical or labeling error, follow its stated correction process. If the grader cannot confirm the slab, pursue the available return or payment remedy and keep the holder sealed as evidence.
