Add a private inventory ID to the digital record, then link it to the grader's certification number. If you need a visible ID, place it on a removable sleeve, bag, or storage location—not on the slab itself. A private inventory ID is a code you control, such as PK-000184. The slab is the sealed plastic holder containing the graded Pokémon card, while its record stores details such as grade, certification number, cost, and location.

Keep Private and Grader IDs Separate
The grader's certification number identifies the encapsulated card in the grading company's system. Your private ID identifies that same item inside your collection, accounting file, or sales workflow. Do not replace or edit the certification number to accommodate your code.
Store the grading company and certification number in separate fields, because different graders may use overlapping number formats. Your record could contain: Treat certification numbers as text when using a spreadsheet. This preserves leading zeros and prevents long numbers from being reformatted.
- Private ID: PK-000184
- Grading company: Example Grader
- Certification number: 01234567
- Card: Charizard

Build an ID System That Scales
Use short, unique, permanent codes. Sequential IDs such as PK-000001 are easier to scan and type than codes containing the card name, grade, price, or storage location. Descriptive codes become inaccurate when circumstances change.
A code such as ZARD-PSA10-BOX2 stops making sense after a regrade or move, while PK-000184 can remain attached to the record throughout its history. A practical setup process is: If your collection app lacks a private custom field, maintain a master spreadsheet or database. Avoid placing the code in a public title or description unless you intend buyers to see it.
- Assign the next unused private ID.
- Record the grading company and certification number.
- Add front and back photographs.
- Enter the purchase details and current location.
- Check the slab label against the record before saving.
Label the Slab Without Touching the Holder
The safest approach is to keep the private ID entirely digital. Locate the physical card by recording its box, row, slot, or drawer in the inventory record. For faster handling, place a printed code, barcode, or QR code on a removable outer sleeve or team bag. Another option is labeling the storage slot rather than anything surrounding the slab.
Avoid writing on the holder or applying adhesive labels directly to it. Ink, residue, abrasion, or attempted label removal can affect its appearance and complicate a later sale. A sleeve label can become separated from its slab. Whenever you move, list, or ship the card, confirm the grader and certification number instead of trusting the private label alone.
Protect Privacy and Prevent Record Errors
"Private" describes how you manage and display the ID; the code itself does not secure the underlying data. A QR code should normally contain only the opaque inventory ID, not purchase cost, owner details, or an unrestricted link to your database. Limit access to the inventory file and keep a backup.
If several people handle the collection, record status changes consistently so one slab is not listed, sold, or shipped twice. Before selling a slab, photograph its label and verify the certification number against the sales record. Remove any labeled sleeve you do not want transferred, then mark the private ID as sold rather than assigning it to another card.
