Quick answer: A PSA cert number is the unique serial number printed on the label of every PSA-graded slab, linking that slab to PSA's official record of the card and its grade. To verify a PSA cert number, enter it in the cert verification tool on PSA's official website or app, then check that every field and any available images match the slab in front of you. A matching record confirms the certificate exists, but you still need to inspect the holder and label, because counterfeiters can copy real cert numbers onto fake slabs.
Key takeaways
- Every PSA slab carries a unique cert number on its label that can be looked up on PSA's official website.
- A valid lookup proves the certificate exists, not that the card in your hand is the one PSA graded.
- Compare the card name, set line, card number, grade and any certificate images with the physical slab.
- Japanese cards are labeled with Japanese set information, so check language and card number carefully to spot English/Japanese mix-ups.
- Ask for the cert number and clear photos of the slab before paying for any graded card online.
What Is a PSA Cert Number and Where Is It on the Slab?
The cert number sits on the front label inside the top of the slab, printed as a string of digits alongside the grade, card name and set information. It is the one piece of data that ties that specific holder to its entry in PSA's database, so find it before you do anything else.
Reading a PSA label: grade, card name, set line and cert number
PSA labels follow a consistent layout, which makes them easy to read once you know what each line means. Take a store listing such as [PSA 9] {106/100} MEW V as an example. A label for a card like this will show:
- Set line: the year, game and set name. For Japanese releases, this line identifies the card as Japanese.
- Card name: printed in English capital letters, for example MEW V.
- Card number: shown with a # symbol, matching the number printed on the card itself (106/100 in this case).
- Grade: the numeric grade (9) with its descriptor, such as MINT for a 9 or GEM MT for a 10.
- Cert number: the unique serial, usually printed near the barcode.
- Variety or notes: some labels add a line for variants, such as holo or special-print designations.
Write down or photograph every one of these fields. You will compare each of them against the online record in the next section.
Barcodes and QR codes on PSA labels
PSA labels carry a barcode that encodes the certificate, and many newer labels also include a QR code that opens the cert record on a phone. Not every slab in circulation has a QR code, so a label without one is not a warning sign by itself. Older labels are still valid and verifiable the same way, by typing the printed number into PSA's lookup.
In a sequential number set like this Latias ex and Latios pair, each slab still carries its own cert number. Look up every slab individually.
How to Verify PSA Cert Number: Step-by-Step
Type the cert number into PSA's official cert verification tool, compare every field on the record with the label, review certificate images if PSA provides them, and then confirm through the PSA app or label QR code. The whole process takes a few minutes per slab.
Step 1: Enter the number in PSA's official cert verification tool
Go to PSA's official website yourself, by typing the address or using a bookmark, and open the cert verification page. Type the cert number manually, digit by digit, from the label or from a clear photo of it. Do not rely on a link, screenshot or QR code supplied by a seller. A spoofed page can be built to look like a genuine PSA certificate lookup, and a screenshot proves nothing at all.
Step 2: Match every field on the record to the label
Once the record loads, go through it line by line. Every field should match exactly:
| Field on PSA record | What to compare on the slab | Common mismatch to watch for |
|---|---|---|
| Card name | Name on label and on the card visible through the case | Similar Pokémon or a different form (e.g. V vs VMAX) |
| Year / set line | Set line printed on the label | Wrong set, or English set listed for a Japanese card |
| Card number | Number on label and on the card itself | Same name, different number (a different print or rarity) |
| Variety / notes | Any variant line on the label | Missing or extra variant designation |
| Grade | Grade number and descriptor on label | Record shows a lower grade than the label |
A single mismatch is enough to stop the purchase until the seller can explain it. Grade discrepancies are especially serious, because an altered label showing a higher grade is one of the most direct ways to misrepresent a slab.
Step 3: Compare certificate images when PSA provides them
Some PSA cert verification records include scan images of the slab's front and back, and others do not. When images are present, compare them against the seller's photos or the slab in your hand. Look at details that are hard to fake: centering, the position of the card in the holder, small print marks or whitening on edges, and the exact placement of the label text. If the images show a card with visibly different centering or wear, the card in the slab is likely not the one PSA graded. If no images are available, do not assume the worst, but lean harder on the physical checks covered below.
While you are on the record, you can also open the population report entry for that card. It shows how many copies PSA has graded at each grade, which gives you context for how scarce a given grade is. It also confirms that the card name and number on your label correspond to a real entry in PSA's catalog.
Step 4: Use the PSA app or QR code as a second check
PSA also offers an official app that can look up certificates. Scanning the label's QR code or barcode with it is a useful second check once you have already typed the number manually. Use it to confirm that the code on the physical label points to the same cert you looked up. If the code leads somewhere else, or to a different certificate number than the one printed, treat the slab as suspect.
What Does a PSA Cert Lookup Prove, and What Doesn't It?
A successful lookup proves that PSA issued a certificate with that number for a specific card and grade. It does not prove that the holder in front of you is the original slab, or that the card inside has never been swapped. Treat the cert check as the first half of a two-part verification.
Cloned cert numbers on counterfeit slabs
Counterfeiters do not need to invent cert numbers. They can copy a real number, along with the matching card name, set and grade, from a genuine slab and print it on a fake label. That fake will pass a lookup perfectly, because the record it points to is real. This is why the image comparison in Step 3 and the physical inspection below matter so much.
A practical red flag: if you find the same cert number in more than one listing, on different marketplaces, or in photos showing slabs with slightly different cards or labels, at least one of them is fake. Searching the cert number online before you buy can surface these duplicates.
Card swaps, resealed holders and altered labels
A genuine PSA holder can also be tampered with. Common methods include:
- Card swap: the holder is opened, the graded card is removed and a lower-condition copy of the same card is inserted. The label and cert remain genuine.
- Label swap: a higher-grade label from another slab is moved into the holder.
- Altered label: the grade on a real label is changed or reprinted.
In each case, the lookup returns a valid record, so the evidence of tampering lives in the holder and label themselves.
Why slab trust comes up so often in collector communities
Collector forums and Reddit threads regularly feature frustration with PSA and worries about slab reliability, from grading consistency to fakes. The underlying concern is reasonable: graded cards change hands for significant sums, which attracts counterfeiters. Rather than taking any slab on faith, collectors who verify the record and then inspect the slab physically remove most of the risk.
How Can You Check PSA Slab Authenticity Beyond the Cert?
Inspect the label for crisp printing, consistent fonts and security features, then examine the holder for clean seal edges, pry marks and proper card fit. Comparing the slab side by side with one you know is genuine is the most reliable way to catch differences.
Inspecting the label: print quality, fonts, alignment and security features
- Print quality: text should be sharp, with no fuzzy edges, bleeding ink or pixelation when zoomed in on a high-resolution photo.
- Fonts and spacing: letter shapes, sizes and spacing should be consistent across all lines. Mismatched fonts on the grade line are a classic sign of an altered label.
- Alignment: the label should sit straight and centered in its compartment, not tilted or shifted.
- Security features: PSA labels include holographic security elements. Compare these with a known genuine slab or PSA's own published guidance rather than relying on descriptions from sellers.
Inspecting the holder: seal edges, signs of opening and card fit
- Seal edges: the join around the holder should be clean and uniform, with no glue residue, cloudy patches or uneven seams.
- Pry marks: look for small dents, scratches or stress marks along the edges, especially near corners, where tools are typically inserted.
- Cracks: any crack in the holder breaks the seal and means the card's condition can no longer be guaranteed.
- Card fit: the card should sit squarely in the inner holder. A card that rattles, sits crooked or looks undersized for the well deserves a closer look.
- Card details: everything visible through the case, including centering, edges and print, should match the certificate images if PSA has them.
Comparing against a slab you know is genuine
If you own a PSA slab you bought from a trusted source, use it as your reference. Place the two side by side and compare label color, font weight, holographic elements, holder thickness and seal finish. If you are working from photos, ask the seller for images taken at the same angle and lighting as your reference shots. Small differences that are invisible in a single photo often become obvious in a direct comparison.
PSA Cert Number on Japanese Cards: What to Check Differently
For Japanese cards, confirm that the PSA record identifies the card as a Japanese release, that the card number visible through the case matches both the label and the record, and that the language of the card itself matches. English and Japanese prints of the same Pokémon can be easy to confuse.
Japanese set information and romanized card names on the label
PSA labels for Japanese cards identify them as Japanese, typically with the word JAPANESE in the set line, while the card name appears in English capital letters. That means the label will not show the Japanese text printed on the card. Your job is to confirm the record reflects the Japanese version, not the English print of the same card, and that the card name on the label is the one you are actually looking at.
Matching card numbers such as 106/100 or 074/067, and older cards printed without set numbers
Modern Japanese cards carry a printed number in the lower corner, and that number is your strongest cross-check. Store examples show how this works:
| Store listing | Card number on label | What to confirm |
|---|---|---|
| [PSA 9] MEW V | 106/100 | Card visible in the case reads 106/100; record shows MEW V, #106, grade 9 |
| DRAGONITE V | 074/067 | Card reads 074/067; record lists the same name and number |
| PENNY | 100/078 | Card reads 100/078; record lists PENNY with the same number |
Numbers above the set total, like 106/100, indicate secret rares, and the same character often has several prints at different numbers within one set. A slab labeled with one number but holding a card printed with another is a swap red flag.
Many older Japanese cards, including vintage holos such as the store's LUGIA-HOLO and RAICHU-HOLO listings, were printed without a set number. For these, rely on the set line, the card name and the artwork. Compare the artwork through the case with the certificate images, or with a reference image of the correct Japanese card from that set.
Spotting English vs Japanese version mix-ups
If the card in the slab is clearly Japanese but the record describes an English set, or the reverse, stop. A genuine PSA slab should not hold a card in a different language from its record. This mismatch usually means the holder was opened and the card replaced, or the label came from another slab. Check the text on the card itself through the case. Japanese cards show Japanese attack names and text, which makes the language easy to confirm in a clear photo.
Buying PSA Graded Japanese Cards Online: Pre-Purchase Checklist
Before paying for any graded card online, get the cert number and clear photos of the actual slab, run the lookup yourself, and compare photos against the record. Walk away from listings that use stock images, show blurred labels or come from sellers who refuse to share the cert.
What to ask a seller before you pay
- The full cert number, typed out in text as well as visible in photos.
- Clear, high-resolution photos of the front and back of the actual slab, showing the full label and all holder edges.
- Close-ups of the label and the seal edges if anything looks unclear.
Then run the lookup yourself, compare every field and any certificate images, and inspect the photos with the label and holder checklist above.
Red flags in graded card listings
- Stock photos or images that do not show the specific cert number.
- Blurred, cropped or glare-covered labels, especially over the grade or cert number.
- A seller who refuses to share the cert number or additional photos.
- The same cert number appearing in other listings or older sales with different-looking slabs.
- A lookup "link" provided instead of the number itself.
- A record whose language, card number or grade does not match the slab.

FAQ
What should I do if a PSA cert number returns no result?
Re-type the number slowly and compare each digit against a clear photo of the label, since transposed or missing digits are the most common cause. If the correct number still returns nothing, do not complete the purchase. Ask the seller for an explanation and contact PSA directly. Treat the slab as unverified until the record is confirmed.
Can two different slabs show the same PSA cert number?
No. Each certificate number is assigned to one graded card, so two slabs showing the same number means at least one of them is not genuine. If you see the same cert listed by different sellers or in different photos, treat both listings with caution and compare each against PSA's record and certificate images.
Does PSA cert verification work for Japanese Pokémon cards?
Yes. Japanese cards graded by PSA get cert numbers like any other card, and the lookup works the same way. The record should identify the card as a Japanese release, so check that the set line, card name and card number match the Japanese version sitting in the slab.
Is scanning the QR code on a PSA label enough to confirm a slab is real?
No. A QR code only leads to a record, and a counterfeit label can carry a code copied from a real slab. Also, a code in a seller's photo could point to a lookalike page. Type the cert number manually on PSA's official website or app, then inspect the label and holder physically.
Why doesn't my PSA certificate lookup show any card images?
Certificate images are not available for every cert, so a record without photos is not automatically suspicious. In that case, rely more on the text fields, the physical inspection of the label and holder, and clear seller photos of both sides of the slab.
Should I verify the cert number again after a PSA slab arrives?
Yes. Run the lookup again with the slab in hand, confirm the number on the label matches the one in the listing, and compare the card, label and any certificate images under good light. This is also the moment to check the seal edges and card fit closely.
