How do I check a PSA certification number?

Go to psacard.com, find the certification verification tool, and enter the number printed on the slab label. PSA returns the card it was issued for, the grade, and population data. It is free and takes about ten seconds.

What does a PSA certification number prove?

It proves PSA graded a card with that number, and tells you which card and what grade. It does not prove the slab in front of you is that slab — a photograph can be of someone else's card, or a listing can attach the wrong number. Checking the number tells you what should be in the slab; matching it against the card and label in the photo is the second half of the job.

Can PSA certification numbers be faked?

Counterfeit slabs exist, which is why the check matters. A fake slab may carry a number that belongs to a genuinely graded but different card. That is precisely why you compare the card PSA reports against the card you are actually looking at, rather than treating a valid lookup as the end of the process.

Do CGC and Beckett have the same thing?

Yes. Both run public certification lookups on their own sites, and the same approach applies: check the number, then confirm the card and grade it returns match what you are being shown.

How to check a PSA certification number

Every PSA slab carries a certification number, and anyone can look it up free in about ten seconds. It is the single best protection a buyer has when spending real money on a graded card, and most people never do it.

The check

Find the number on the label. Seven or eight digits, usually bottom right of the printed label inside the slab. On a listing photo it should be legible; if it is deliberately cropped or blurred, that is your answer.
Look it up at psacard.com. Their certification verification tool is free and needs no account. Enter the number.
Compare what PSA returns against what you are being shown. PSA reports the card name, set, year and grade. Every one of those should match the label in the photo and the card visible through the slab. This third step is the one people skip, and it is the only one that actually catches anything.

PSA also reports population data — how many of that card exist in that grade, and how many graded higher. Useful for judging whether a price is reasonable, though it is not what you are verifying here.

What the number proves, and what it doesn’t

It does prove

PSA graded a card under that number.
Which card it was, and at what grade.
How rare that grade is for that card.

It does not prove

That the slab you are looking at is that slab. A photo can be of a different card entirely.
That the listing attached the right number to the right item.
That the seller actually holds it.

This is why the comparison step matters more than the lookup. A valid certification number tells you what should be there. Only checking it against the card in front of you tells you whether it is.

A live example of why this is not theoretical

While reviewing a vaulting platform we found a listing whose slab image showed one card — the label and artwork both clearly identifying it — while the certification number printed on that same image resolved at PSA to a completely different card from the same set, with a different value.

The platform’s own listing title and price described the card the certification number pointed to, so their data appears correct and the image is the part that is wrong. But a buyer scanning the purchase page sees the image, not the metadata. Ten seconds with the certification number was what surfaced it.

We have put this to the platform and are not naming them until they have had a chance to respond — an innocent explanation like a mismatched image asset is entirely plausible. We will publish their answer either way. The transferable lesson stands regardless: check the number, then check it matches.

When to bother

Honestly? Any time real money is involved, because it costs ten seconds. But it matters most when the photo is the only thing you have to go on: buying from an individual seller rather than a marketplace with a returns process, buying a card whose value depends heavily on its grade, or buying a vaulted card you cannot physically inspect before paying.

CGC and Beckett run equivalent lookups on their own sites. The same three steps apply.
