How to check Japanese Pokémon TCG is authentic and factory sealed: a checklist for buyers and for vetting a supplier

Most authenticity guides are written for a collector holding one box. A shop or reseller buying six boxes or a full case has more to check and more to lose: you are putting that stock on your own shelves, under your own name, and one resealed box can cost you a customer.

The Pokémon Company has warned buyers about unauthorised products sold online and in shops, and says it is pursuing legal measures and working with sales platforms to stop those sales. Counterfeit singles get most of the attention. With sealed product, the usual problems are resealed boxes (opened, searched and rewrapped) and product that isn't what the listing says.

Inspect each box under good light before you open anything, and compare it with a box from a source you already trust. Collector guides commonly list these signs:

• Shrink wrap: even, and the same as other boxes from the lot. Factory wrap is snug but can have a little slack at the corners; baggy wrap, or wrap shrunk so hard that the corners look rounded or melted, points to a heat gun
• Seams: a single clean factory heat seal. A second seam, an overlapping fold or tape under the wrap is a strong sign the box has been opened and rewrapped
• Flaps and glue: flaps sit flush, with no tape or fresh glue visible through the wrap. Some glue marks are normal on factory boxes, so compare with a box you trust
• Print: sharp text and logos, the correct Japanese set name and set code (for example M6a), and colours that match other boxes of the same set
• Weight: boxes from the same lot should weigh about the same on a postal scale. A box missing packs will read light
• JAN barcode: present, undamaged, and matching the set named on the box

No single sign proves a box is genuine. Look for several consistent signs, and treat any one clear reseal sign as a reason to stop and ask.

The JAN is the 13-digit barcode number on Japanese retail products. JAN codes are GS1 numbers, and GS1 Japan issues company prefixes beginning 45 or 49 to Japanese brand owners, so a Japanese Pokémon TCG box should carry one.

Check the number against established Japanese retailer listings for the same set. For example, Japanese shop listings give 4521329462424 for the 30th Celebration (M6a) booster box. You can also check which company a barcode number is licensed to with Verified by GS1.

A matching JAN doesn't prove a box is sealed, because a resealed box keeps its original barcode. It does catch mislabelled or substituted product, and it lets you confirm that a supplier's photos show the product you are paying for.

When you buy by the case, check the outer carton before you open it, and photograph it as it arrived.

• The outer carton is intact, with no cut and re-taped seams and no crushed corners that suggest it was opened and repacked
• Any product name, set code or barcode printed on the carton matches the boxes inside
• Every box inside is the same product, with matching barcodes and print
• The box count matches the case size for that product. Case sizes vary by set; see our buyer guides for Japanese box and case sizes
• The shipment matches your commercial invoice line by line

Report transit damage, shortages or wrong items to your supplier promptly, with photos. Our own window is 7 days from delivery; see returns.

Box checks happen after you have paid. Supplier checks happen before, which is why they matter more at volume. Before your first order, ask for or check:

• A commercial invoice with the goods, quantities, unit prices and full value, for every international shipment
• A business name and contact details you can verify, and published terms for shipping, payment and returns that say what happens if goods arrive damaged, short or not as described
• Photos of the actual stock you are buying, not stock images, showing the shrink wrap, the set code and the JAN barcode
• A clear answer on what they will do if you believe an item is not genuine
• Payment terms you understand. Know what recourse each method gives you before you pay: card payments usually have a dispute process, while cryptocurrency payments typically can't be reversed and a bank transfer can be hard to recover once it has been sent

• Prices far below the Japanese market. New releases often trade above retail in Japan, so a supplier offering them far below what Japanese shops pay needs a very good explanation
• Refusing to photograph the stock you are buying, or sending only stock images
• Offering to declare a trade order as a gift or at a low value. It is an offence in both the exporting and importing country and can void carrier insurance, and a supplier willing to falsify customs paperwork has shown you how it treats paperwork
• Pressure to pay immediately, before you have an invoice or terms
• No business name, no contact details and no written terms
• Mixed lots: boxes in one case with different barcodes, print or weights
