How to Verify a PCGS or NGC Certification Number — And Why You Should Every Time

The 30-Second Check That Can Save You Thousands

Every coin graded by PCGS or NGC receives a unique certification number. That number is your direct link to the grading service's database — and verifying it is the single most important step you can take before buying a certified coin. It's free, it takes 30 seconds, and it can save you from buying a counterfeit. Here's exactly how to do it.

PCGS Cert Verification

URL: pcgs.com/cert

The PCGS certification number location — look for the digits following the slash on the label.

Steps:

1. Go to pcgs.com/cert (type it manually — do not follow links from QR codes on the holder unless you've verified the holder is genuine).
2. Enter the PCGS certification number. On a PCGS holder, this is the number following the slash (/) on the label — typically 7 or 8 digits.
3. Click "Verify."

What you'll see for a valid cert number:

• Coin identification: Denomination, date, mintmark, and variety
• PCGS grade
• Population data: How many coins have been graded at this grade, and how many graded higher
• PCGS Price Guide value
• Auction history: The coin's auction appearances, when PCGS has recorded them
• High-resolution images (when available)
• Set Registry presence: Whether the coin is currently registered in a PCGS Set Registry set

The PCGS Cert Verification page — a valid lookup returns the coin description, grade, population data, and images.

What if the cert number returns "not found"? The holder is almost certainly counterfeit. Do not proceed with the purchase. In rare cases, very recently graded coins may take a day or two to appear in the database — but if the seller claims the coin was graded more than a week ago and it's not in the system, walk away.

NGC Cert Lookup

URL: ngccoin.com/certlookup

The NGC certification number location on the holder label.

Steps:

1. Go to ngccoin.com/certlookup (again, type it manually).
2. Enter the NGC certification number from the holder's label.
3. Click "Look Up."

What you'll see for a valid cert number:

• Coin description and NGC grade
• NGC Census population data
• NGC Price Guide value (for many coins)
• High-resolution obverse and reverse images (when available)

The NGC Cert Lookup page — showing grade, census data, and high-resolution images for verified coins.

Mobile Verification

Both services offer mobile options:

• PCGS: The PCGS Cert Verification app (available on iOS and Android) lets you scan the barcode or the QR code on the label, or enter the cert number. Some recently graded holders carry PCGS's Gold Shield NFC chip, which you can verify by tapping your phone to the holder.
• NGC: The NGC app supports barcode scanning, so you can look up a coin without typing its number.

Why You Should Verify Every Time

Even experienced collectors should make verification a habit because:

1. Counterfeit slabs are increasingly sophisticated. Visual inspection alone is no longer sufficient to detect the best fakes.
2. "Cert number spoofing" is real. Some counterfeiters use legitimate cert numbers on fake holders — the number will verify correctly, but the coin inside isn't the one PCGS or NGC graded. Compare the images returned by the verification lookup to the actual coin in the holder.
3. Genuine labels can be reused. A real label can be moved into a fake or resealed holder with a different coin inside. The cert number verifies, but the coin doesn't match.
4. It's free and fast. There is no cost to verify a cert number, and it takes less than a minute on desktop or mobile.

Warning: Clone Verification Websites

Sophisticated counterfeiters have created fake versions of the PCGS and NGC verification websites (see our post on Mirror-Clone Grading Websites). These clone sites look identical to the real ones but return fabricated "verified" results for counterfeit cert numbers. Always type the URL manually:

• PCGS: pcgs.com/cert
• NGC: ngccoin.com/certlookup

Be suspicious of any lookalike address, such as one with extra words, hyphens or characters added to the name. PCGS and NGC do run regional sites, so if a link takes you somewhere unfamiliar, go back and type the address above yourself.
