How do I look up a TAG cert number?

Enter the number inscribed on the slab below and press Check the cert: the direct link to the card's report on TAG's own site and the loss register's answer.

What does "not in the index" mean?

For TAG numbers the index is not read, because it carries no TAG certs. The check reads the loss register and links to TAG's own record, which is the lookup that answers.

What is on TAG's record?

The card, the grade and its view score, centring, corners, edges and surface front and back, measured height and width, the defects TAG identified by location, the date graded, and population and rank figures with their as-of date.

Is Brich House affiliated with TAG?

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

TAG cert lookup: what the record shows

Enter the cert number inscribed on the TAG slab. We build the direct link to the card's record on TAG's own site, the DIG report, and show whether the number has an open report in the Brich House loss register. The record shows; TAG decides.

How a TAG cert number looks

TAG prints no paper label: the grade, the card's data and the cert number are inscribed inside the slab, with a QR code that TAG says opens the same report. Read it off the slab itself, as printed.

TAG states no number format on the pages we read. The numbers we have seen read as one letter and seven digits, N1491291 for example; the check takes letters and digits of 4 to 14 characters.

Where TAG's own record is

TAG's record for a card opens at my.taggrading.com/card/<cert>. The link under every result carries the number into that address, and the report opens without a sign-in: grade, centring, defects, dimensions, population and chronology as of the day you open it, and images front and back.

Opened in a browser on 8 November 2026 on TAG's own site: the address pattern opened the record directly. TAG's main site also lists a cert search under its pop report menu.

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. It carries no TAG certs, so for a TAG number the check reads the loss register and links to TAG's own record.
02The duplicate check. In the bulk check, the same TAG cert twice in one list is flagged. One slab carries one cert; a repeat is a reason to look, never 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/tag/<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. For TAG numbers the register and TAG's own record are the two reads.

What the check does not do

It does not fetch, copy or keep TAG's record; we build the link, and TAG's own page is the record of what TAG graded.
It does not say a card is what it says it is, or that it is not; the record shows, TAG 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.
