CheckCOA is the all-in-one, free TAG Grading cert lookup: verify a serial number and view the key DIG (Digital Image and Grading) report data (grade, population, card rank and corner, edge, centering and surface subgrades), with every result screened against our Fraud Base of known fake, stolen, reused or compromised numbers and 25+ authentication providers supported. Scan the slab QR code, use camera OCR, or type the 8-character serial (one letter and seven digits, e.g. V1234567) to get the main TAG record without the clutter.
Checking more than TAG? CheckCOA also verifies PSA, JSA, Beckett, SGC, CGC and 20+ more grading and authentication providers in one place.
Enter the 8-character TAG serial (one letter and seven digits, e.g. V1234567), scan the slab QR code, or use camera OCR.
TAG Grading publishes a DIG (Digital Image and Grading) report for each certified card. This lookup verifies the serial and surfaces the key parts of that report so you can match the record to the item in front of you, with a Fraud Alert screen on every check.
The TAG grade (for example 8 NM MT) plus corner, edge, centering and surface breakdowns from the DIG report when available.
Card identity, graded slab and raw images, population and card rank, so you can confirm the record matches the card.
CheckCOA pulls the main TAG record without the extra pages, and screens the number against Fraud Alerts.
You can verify a TAG certificate three ways, and every method runs the same check with Fraud Alert screening.
A standard provider lookup can confirm whether a TAG record is available. CheckCOA adds an all-in-one workflow with QR scan, camera OCR, manual entry, saved history and Collections, plus Fraud Alert checks against known fake, stolen, reused or compromised certificate numbers.
A counterfeit holder can copy a serial number from a genuine public record. CheckCOA screens every TAG cert lookup against a growing database of more than 25,000 reported fake, stolen, reused and compromised certificate numbers so collectors can avoid already-reported risks before buying.
A clean result is not a guarantee of authenticity. Always compare the card, slab, grade and seller history before buying.
Use this TAG Grading cert lookup before you buy or sell. Compare the serial, grade, subgrades, images and returned record with the slab in front of you, then review any Fraud Alert warnings for known fake or reused certificate numbers.
Check the TAG record when available and screen the number with free Fraud Alert protection.
Use the serial or QR to open the record, then compare its card identity, images and scoring information with the slab being offered.
The TAG slab label provides the identifier used for verification, and supported holders may include a QR code leading to the card’s digital record. Scan the QR or enter the printed serial exactly as shown. If glare prevents a reliable scan, use a close-up photo or manual entry rather than repeatedly accepting uncertain OCR. Ask a seller for both the label close-up and full front-and-back slab photos so the identifier can be tied to the specific card being offered.
A TAG DIG Report is the digital grading record associated with a TAG-certified card. Depending on the record, it may provide high-resolution imagery, card identification and a detailed scoring or defect breakdown beyond the grade printed on the slab. Use it as a comparison source: the report should describe the same card, variation and visible characteristics. Availability and detail can vary, so a shorter record is not automatically invalid, but it gives you fewer independent points to confirm.
Confirm the certification number, year, set, player or subject, card number, variation and final grade. Compare available report images with centering, print marks and other visible features of the card in the listing. When a scoring breakdown is present, make sure it belongs to the same certification rather than a screenshot from another report. A serial-number match with a different card image, description or grade is a material warning that must be resolved before purchase.
Recheck every character and try manual entry if QR or OCR recognition was uncertain. Confirm that the item is a TAG-graded slab and that the seller has not supplied an order number or another reference instead of the certification number. Recently issued records, older data or temporary provider availability can affect results. If the record stays unavailable, request a fresh label photo and the direct provider record from the seller, then seek provider confirmation for a high-value card.
Open the available report at full resolution and compare the card’s front and back, centering, corners, surface marks and printed identifiers with current seller photos. A seller may reuse attractive report screenshots, so verify that the serial shown in the report matches the slab label. Review the scoring breakdown for consistency with the overall grade, but do not treat a report as proof that the physical holder in a listing has not been copied or altered.
Review the seller’s history, price and photo consistency; search for the same serial or images in other listings; and request a fresh timestamped photo for expensive cards. Inspect the holder and label for visible tampering and compare the exact card variation. CheckCOA screens the number against reported Fraud Alerts, but a clean result only means that no matching report is currently stored. Protected payment and an inspection after delivery remain important for high-value transactions.
Yes. Verifying a TAG serial number on CheckCOA is free and needs no account. Enter, scan or OCR the serial to check the TAG record when available and screen it against Fraud Alerts for known fake, stolen, reused or compromised numbers.
A TAG serial is eight characters: one letter followed by seven digits, for example V7872225. Enter all eight characters exactly as shown on the slab. CheckCOA keeps the Verify button inactive until a valid eight-character serial is entered so short or mistyped numbers are not submitted.
Yes. CheckCOA supports scanning the slab QR code, reading the printed serial with camera OCR, and manual entry. All three run the same verification and Fraud Alert check, so use whichever is easiest for the slab in front of you.
CheckCOA surfaces the key parts of the TAG DIG report: the grade and label (for example 8 NM MT), corner, edge, centering and surface subgrades and dimensions when available, plus card images, population and card rank. It focuses on the main record without the extra pages, and adds a Fraud Alert screen.
Yes. Every TAG Grading lookup is screened against CheckCOA's Fraud Alert database of 25,000+ known fake, stolen, reused and compromised certificate records. This helps flag known fake COAs, counterfeit slabs, reused serial numbers and other reported risk signals, but it does not replace expert authentication.
All-in-one cert lookup across PSA, Beckett, CGC, Upper Deck, BGS and 20+ more. Every scan is auto-checked against our growing Fraud Alert database - 25,000+ known fake, stolen, reused & compromised certificates.
