- Population report link — Cert verification shows how many of that card exist at each grade.
How Do You Verify a PSA Graded Card?
Every PSA-graded card has a unique certification number printed on the slab label. This number is the key to verifying authenticity, confirming the grade, checking population data, and viewing recent auction prices. With counterfeit PSA slabs becoming increasingly sophisticated, cert verification is an essential skill for every collector. This guide shows exactly how to read and verify PSA certificate numbers.
Where to Find the PSA Certificate Number
The cert number is located on the PSA slab label in two places:
On the Slab Label
- Location: Bottom-right corner of the front label
- Format: 8-10 digits (e.g., 12345678 or 0123456789)
- Font: Clean, crisp printing — fake slabs often have blurry or misaligned numbers
On the PSA Logo Sticker
- Location: Holographic PSA sticker on the back or side of the slab
- Security feature: Sticker changes appearance when tilted
- Number matches: The sticker number should match the label number exactly
On the QR Code (New Slabs)
- Location: Bottom-left of the label on slabs produced 2020+
- Scan with phone: Links directly to the cert verification page
- Quick verification: No typing required — scan and confirm instantly
How to Verify Online
Step-by-Step Verification
- Go to psacard.com/cert
- Enter the 8-10 digit cert number in the search box
- Click "Verify"
- Review the results page for card details, grade, and scan images
What the Results Page Shows
| Field | What It Tells You |
|---|---|
| Brand/Set | The card set and year |
| Card Number | Number within the set |
| Player/Description | Player name or card subject |
| Grade | PSA 1-10 (or Authentic/Altered) |
| Card Scan | Image of the graded card in slab |
| Population | How many exist at this grade |

What to Check:
- Card matches — Does the verification show the same player/card you are holding?
- Grade matches — Does the online grade match the slab label?
- Image matches — Does PSA's scan look like your card?
- Cert number valid — If "Not Found," the cert is fake or invalid
Spotting Fake PSA Slabs
Counterfeit PSA slabs are a growing problem. Here is how to identify them:
Red Flags for Fake Slabs
| Red Flag | What to Look For |
|---|---|
| Cert not found | psacard.com/cert returns "Not Found" |
| Mismatched card | Verification shows different player than slab |
| Mismatched grade | Online grade differs from slab label |
| Blurry label | Text is fuzzy or misaligned; real PSA labels are crisp |
| No hologram | Missing PSA holographic sticker |
| Wrong slab shape | Slab dimensions differ from genuine PSA slabs |
| Price too good | PSA 10 selling for significantly below market price |
| Suspicious seller | New account, no feedback, stock photos |
Physical Inspection Tips
- Slab clarity — Genuine PSA slabs are crystal clear; fakes may be cloudy or yellowed
- Label adhesion — Real labels are seamlessly integrated; fake labels may peel at edges
- Weight — Genuine PSA slabs have consistent weight; fakes may feel lighter
- Edges — PSA slab edges are smooth and uniform; fakes may have rough edges
When in Doubt: If anything seems suspicious, do not buy. Request additional photos, ask the seller to provide the cert number before purchase, and verify independently. For high-value cards ($500+), consider buying only from established dealers or auction houses.
QR Code Verification (2020+ Slabs)
PSA introduced QR codes on slabs in 2020 for instant verification:
How to Use QR Verification
- Open phone camera or QR scanner app
- Point at QR code on bottom-left of slab label
- Tap the link that appears
- Review cert page — should load psacard.com/cert with your card details
Advantages of QR Verification:
- No typing errors — Eliminates mistakes entering cert numbers
- Instant results — Direct link to verification page
- Mobile-friendly — Verify at card shows, shops, or before in-person purchases
- Harder to fake — Counterfeiters rarely replicate working QR codes correctly
Note: Pre-2020 slabs do not have QR codes. For older slabs, manual cert number entry at psacard.com/cert is required. Read our doctored card guide for more authentication tips.
Checking Auction Prices by Cert
PSA cert verification includes recent auction data:
Price Data on Cert Page
- PSA Auction Prices — Realized auction prices from major auction houses
- SMR Price Guide — PSA's monthly price guide values
- Time range — Recent sales (last 90 days typically)
