Yes—save the marketplace item number for every valuable Pokémon slab purchase. On eBay, this item ID identifies the purchased listing, while the 12-digit order number identifies the transaction. Keep both numbers with a copy of the listing and payment details. Together, they create a stronger record for insurance, disputes, collection management, and future resale.

Item ID, order number, and certification number
These three numbers serve different purposes. The marketplace item ID connects the slab to its listing, including the seller's photos, description, price, and terms. The order number identifies the transaction.
As eBay Help explains, buyers should not treat the item ID and 12-digit order number as interchangeable. A grading-company certification number identifies the encapsulated card. For example, a PSA certification number can be entered in PSA's certification database, but it does not identify your eBay transaction.
What should you save at purchase?
Record the evidence while the listing is easy to access. A useful purchase file should contain: This matters because eBay Purchase History retains orders for seven years.
A personal archive preserves the details after that platform window ends. Save the files under a consistent name, such as "PSA-cert_item-ID_purchase-date." That makes the transaction evidence easier to match with the physical slab.

Why the PSA certification lookup is not enough
A successful certification lookup is useful, but it does not prove that the slab in your possession is genuine. PSA warns that counterfeit labels can reuse authentic certification numbers found in public records. Compare the slab with every available image.
Check the card, label details, holder condition, certification number, and any visible marks against the original marketplace listing. Qualifying higher-end PSA-encapsulated items may also have front-and-back SecureScan images. PSA says collectors may use SecureScan images for personal records, including insurance purposes. The strongest file therefore connects several forms of evidence: the certification record, marketplace item ID, listing images, order details, and your own current photographs.
What eBay authentication does and does not cover
For eligible graded cards, eBay's Authenticity Guarantee inspects the sealed holder for tampering and verifies the case and label. Authenticators also compare the item with the listing's title, images, and description. In the United States, coverage includes eligible individual Pokémon and other collectible-card-game singles priced at $250 or more. Eligible graded cards must be from PSA, SGC, CGC Cards, or BGS.
Sets, lots, packs, and local-pickup listings are excluded. Authentication is also not grading or re-grading, so it does not replace your own condition and certification records. Some authenticated purchases can become final sale when the seller offers no returns or the return window has passed. Save the item ID, listing terms, and authentication documentation as soon as the order arrives.
Build a durable record in five minutes
Create one digital folder for each important slab. Do not rely on a marketplace account, an email receipt, or a certification lookup alone. If you later sell, insure, or question the slab, this folder shows exactly which item was advertised, what you paid, and which physical holder you received.
- Export or screenshot the complete listing.
- Copy the item ID and 12-digit order number into a text note.
- Add the purchase date, price, seller, grading company, and certification number.
- Photograph the slab's front, back, label, and holder after delivery.
- Back up the folder somewhere separate from the device holding the original.
