Counterfeit checks can reveal warning signs, but a photograph, barcode or quick test cannot certify every card or sealed product. Start with the exact item and its provenance. If you cannot resolve a concern, pause the purchase rather than treating uncertainty as proof of authenticity.
Check the offer first
Compare the same product, language and condition across established sellers. An unusually low price calls for investigation, but it is not itself proof of a counterfeit. A high price or specialist-shop label is not proof of authenticity either.
Ask who sells and ships the item. For private listings, request clear photographs of the actual card or box and review the seller's history and the platform's buyer-protection terms.
Identify the exact card
Use the set, collector number, language and printing together. Compare artwork, text, symbols and any expected texture with reliable images of that same version. Not every foil card is textured, and a different edition is not a suitable reference for every detail.
Pokémon Support's counterfeit guidance describes checks that may help identify fakes. Treat visual and light checks as evidence to consider together, not a certificate. Do not tear, bend, scratch or apply heat to a card you are trying to verify.
Inspect sealed packaging
Compare the exact product with official contents and images. Look for damage, adhesive residue, disturbed seals or inconsistencies, and ask the seller to explain them. Packaging can differ between products and print runs; one fold style does not establish authenticity.
A barcode can help check product identity, but it can be copied and does not prove what is inside. A missing result in a third-party barcode database is not, on its own, proof of a fake. Do not rely on pack weight as an authenticity certificate or a promise of valuable contents.
What grading and seller reputation do not prove
For a graded item, verify the label and certification details with the named grading company and compare them with the actual slab and card. A certificate number alone does not rule out a copied label or mismatched item. Keep the exact grader, grade and designation distinct.
A seller's history can inform a decision, but no retail channel has zero risk. Imported language versions also need product-specific checks rather than assumptions about their country.
If something remains unclear
Ask for more photographs or an explanation before paying. Consider a qualified in-person assessment for a valuable item. If you suspect a counterfeit after purchase, preserve the listing, messages, packaging and proof of payment and contact the seller or platform through its stated process.
