A high-value Pokémon slab sale does not automatically require a seller identity check. Such checks may matter when a marketplace requires identity, ownership, or regulatory verification based on its rules—not simply because the card is expensive. A slab is a professionally graded card sealed in a protective holder. Buyers and sellers should distinguish seller verification from card authentication because each addresses a different risk.

What does each type of check prove?
A seller identity check connects an account to identifying information. It does not necessarily prove that the seller owns the card, has the right to sell it, or described it accurately. An ownership check may require purchase records, provenance, or other evidence connecting the seller to the slab.
Item authentication instead examines the card and compares it with the listing. These protections are not interchangeable. A verified person can list a questionable card, while an authentic card can still come from a seller whose identity was not certified to the buyer.
How eBay handles eligible graded cards
eBay automatically sends eligible graded trading-card singles, including qualifying PSA slabs priced or auctioned at $200 or more, to a vetted third-party authenticator. The authenticator checks the item's authenticity and whether it matches the listing, according to eBay's trading-card Authenticity Guarantee terms. If the authenticator cannot verify the card or finds a material listing mismatch, eBay returns it to the seller, cancels the purchase, and refunds the buyer.
That process checks the item and listing; eBay does not describe it as seller-identity certification. A costly slab can still fall outside the program. Exclusions include listings without the program badge, local pickup, offline payments, P.O.-box shipments, and certain other categories. Buyers should confirm eligibility on the individual listing instead of relying on the grade or price alone.
When proof of ownership may be requested
Some venues apply a more direct ownership screen. Catawiki says a trading-card submission valued at €500 or more may require provenance, high-resolution images, and proof of ownership before approval under its trading-card submission guidelines. That requirement can matter to someone consigning a valuable Pokémon slab, but it remains venue-specific.
Approval shows that the requested submission evidence passed that marketplace's review; it is not a universal title history for the card. A grading label or certification record should not be treated as proof that the current seller owns the slab. Buyers seeking that assurance should ask what documentation the selling venue reviewed and what remedy applies if ownership is disputed.
Does one expensive sale trigger a legal identity check?
In the United States, sale price alone does not trigger the INFORM Consumers Act. The FTC says qualifying marketplaces generally must collect and verify bank, contact, and tax information from third-party sellers who reach both 200 sales and $5,000 in revenue during a 12-month period, subject to the law's other conditions in its INFORM Consumers Act guidance. The law concerns high-volume sellers of new or unused consumer products.
Whether it covers a particular graded Pokémon card depends on the card's condition, the transaction, and the platform; a single valuable vintage slab is not automatically covered merely because of its price. Retail identity programs can also cause confusion. Pokémon Japan has said it is considering My Number Card verification for selected Pokémon Center Online lotteries and sales from around August 2026, using a smartphone to read the card's IC chip without obtaining or retaining the individual My Number, according to the Pokémon Card Game Official announcement. That initiative concerns selected retail purchases, not documented secondary-market slab resales.
What should buyers and sellers verify?
Before relying on an identity or authentication claim, identify exactly what the platform checks. The most useful questions separate account verification, ownership evidence, and physical card review.
For an expensive private or off-platform sale, do not assume that a grading label supplies the missing protections. Establish the seller's identity, the slab's certification details, the ownership evidence, the payment route, and the dispute remedy separately.
- Confirm whether the exact listing displays an authentication-program badge.
- Check whether the shipping address, payment method, or pickup arrangement creates an exclusion.
- Ask whether the venue reviewed proof of ownership or only account information.
- Keep listing images, certification details, payment records, and shipping evidence.
- Read the platform's refund or return procedure before completing the transaction.
