Do not buy a Pokémon slab with a hidden certification number unless the seller provides another way to verify it before payment. A slab is a graded card sealed in a holder, and its cert number links that specific grading record to the card. Hiding the number is not a security feature described by PSA or CGC. It blocks the independent lookup that helps buyers compare the listing with the grading company's record.

Why a hidden cert number matters
PSA and CGC verification systems rely on the certification number or the label's QR code. Without either, you cannot independently confirm that the advertised card, grade, and holder match an official record. A concealed number does not prove that a slab is counterfeit.
A seller may hide it because they mistakenly believe public cert numbers help scammers. Still, the seller's motive does not remove the buyer's verification problem. Treat continued concealment as a transaction risk, especially if the seller wants irreversible payment or refuses a live verification. PSA's guidance supports obtaining the cert before purchase and comparing the record with the exact slab being offered, including any available SecureScan images (PSA FAQ).
How to verify a PSA slab
Ask the seller for the complete cert number before paying. Enter it yourself in PSA Cert Verification rather than relying on a screenshot or link supplied by the seller. Compare the result with the listing: A valid result is necessary, but it is not proof by itself.
PSA warns that counterfeit labels can reuse genuine numbers found publicly, so the database details must match the physical slab in front of you (PSA Cert Verification). If the seller will not disclose the number in writing, request a live video demonstration. Have them scan the physical label or QR code with PSA's app and show both the returned record and the slab without leaving the camera frame. This is stronger than a static photo, although it cannot completely defeat a reused cert number.

How to verify a CGC slab
For a CGC card, request the cert number or an unobstructed view of the QR code. The label should display the card description, grade, certification number, and QR code. CGC says it images every graded card after encapsulation and makes those images available through Verify CGC Certification.
Compare the database images with the offered card, including its position, visible print characteristics, label information, and holder appearance (CGC grading process). Also inspect the physical holder and label rather than stopping at a successful lookup. CGC describes security features intended to protect against counterfeiting and tampering, but the database match and physical inspection work together.
When a protected marketplace is safer
If direct verification remains incomplete, use a transaction route that adds a physical inspection. For qualifying U.S. eBay purchases, the current trading-card program covers eligible raw and graded collectible-card-game singles priced at $250 or more, including approved PSA, Beckett, CGC, and SGC slabs. Buyer, seller, location, and listing restrictions still apply (eBay Authenticity Guarantee).
That inspection is an added safeguard, not a replacement for checking the cert and images. eBay's service is not grading, and it does not verify in-person autographs, aftermarket patches, or relics. For an ineligible listing or private sale, make cert disclosure a condition of payment. If the seller will not provide the number, perform a live scan, or use an eligible protected transaction, decline the purchase.
