How do I check a CGC cert number?

Enter the number from the front of the label below and press Check the cert: the link to CGC's own lookup with the number carried, the vault-token count and the loss register's answer.

What does "not in the index" mean?

That the number is not among the Collector Crypt vault tokens our watch reads. Most graded cards are in no platform vault, so most certs are not in the index; it says nothing about the slab or CGC's record.

What should I read on CGC's record?

The whole record: card, set, number and variety, the grade, the images CGC took after sealing, and any warning CGC published.

Is Brich House affiliated with CGC?

No. Brich House has no affiliation with CGC; CGC does not endorse this page, and its own lookup is the source of truth for what it graded.

CGC cert check: what the record shows

Enter the number from the CGC label. We build the link to CGC's own cert lookup, the record of what CGC graded, and show what our record holds: the on-chain vault census, the loss register and the duplicate check. The record shows; CGC decides.

How a CGC cert number looks

The cert number is printed on the front of the CGC label with a barcode; CGC says the QR code on the back opens the same record. Copy it from the slab itself, not from a listing photograph.

CGC states no cert number length on the pages we read, so neither do we. The check takes CGC numbers of 7 to 13 digits and tells you when a number falls outside that pattern.

Where CGC's own lookup is

CGC's cert lookup is at cgccards.com/certlookup. The link under every result carries the number into CGC's page, cgccards.com/certlookup/<number>/, which the label's QR code also opens.

CGC's lookup page sat behind a bot check when we opened it on 8 November 2026. The address is the one CGC's labels carry (14 October 2026); CGC's own cert pages, indexed 8 November 2026, use the same form, cgccards.com/certlookup/<number>/<grade>/. If no record opens, enter the number in CGC's box.

What our record adds

01The on-chain census. Our watch reads one public platform vault index, Collector Crypt: 192,482 records on 8 November 2026, from public chain data. If a vault token there names this CGC cert, you see the vault its record names, the card and grade, and when our watch saw it.
02The duplicate check. One slab carries one cert. The result says how many vault tokens name this number; the bulk check flags a cert twice in a list. More than one is a reason to look, not a verdict.
03The loss register. Whether this cert has an open report in the Brich House loss register, by status and reference only.
04A record you can share. Every result has a link, brich.house/check/cgc/<cert>, that runs the check again whenever it is opened.
05The watch. Under every result: Watch this cert. Leave an address; we confirm it by email first. Per-cert alerts are part of the account plan.

What the check does not do

It does not fetch, copy or keep CGC's record; we build the link, and CGC's own page is the record of what CGC graded.
It does not say a card is what it says it is, or that it is not; the record shows, CGC decides, and the slab in hand decides whether it matches.
It does not value the card or say who holds it, and it stores no cert and no address from a check.
