MLB Authentication Lookup (Hologram Sticker Verification)

Enter the two-letter prefix followed by the hologram number as one string, for example CV123456, or scan the QR code on the newer sticker. If the number begins with PX or YP, also enter the three-letter validation code printed next to it. The lookup checks the authentication record when available and screens the number against Fraud Alerts, then compare the returned player, item and event with the item itself.

Two letters followed by a serial number, entered together with no space or dash, like CV123456. On the newer sticker the prefix and serial sit next to each other. On older holograms the two letters may be printed apart from the digits, above, below or beside them, but the letters still go first when you type the number.

MLB updated the hologram format, and those newer serials cannot be checked with the number alone. The validation code is three randomized letters, and they are not printed in plain ink: a small window on the sticker shows a different letter depending on the viewing angle, so you tilt the item to read all three. When you type a number starting with PX or YP, CheckCOA shows a field for it and runs the lookup once all three letters are entered. If a listing photo crops that window out, ask the seller for a full, straight-on picture of the sticker.

A DB numbered hologram is not an authentication hologram. It marks the item as officially licensed, and it is never issued through the MLB Authentication Program for autographed or game-used items, so it will not return an authentication record. Authentication holograms are applied directly to the item itself and carry the silhouetted batter logo.

The most common reasons are a misread character, a licensing hologram rather than an authentication hologram, or a missing validation code on a PX or YP serial. Recheck the letters and digits against a clear photo of the sticker, with no spaces. If it is a genuine authentication hologram and the record is still missing or the details look wrong, MLB asks collectors to email an image of the hologram plus a description and photo of the item to [email protected] for investigation.

Team Issued is a designation from an independent third-party authenticator attesting that the item was issued by the club to its clubhouse. It is not a statement about whether the item was used in a game, or by whom. If a listing presents a Team Issued item as game-used, that difference is worth raising with the seller before you buy.

Off-duty law enforcement officers working as independent contractors, assigned by Authenticators, Inc., attend every Major League Baseball game. Only items they personally witness being signed or used in a game are eligible for the program. Witnessed items then receive a tamper-evident hologram produced by OpSec with a unique alphanumeric combination, which is why items cannot be submitted for authentication after the fact.

Yes. Checking an MLB authentication hologram on CheckCOA is free and needs no account, and every lookup includes a Fraud Alert check against known fake, stolen, reused and compromised numbers. A free account only adds History, Collections and Wishlist so your checks are saved.

Yes. Upload a clear photo and OCR will read the sticker, or scan the QR code on the newer holograms, which carries the prefix and serial together. Always review the detected number before verifying, because characters like 0 and O or 1 and I are easy to misread on a small sticker.

No. The record confirms that the serial exists in the authentication system and what it was applied to. A genuine hologram can be peeled off one item and reapplied to another, and a real serial can be copied into a listing for something else. Compare every returned field with the physical item, check the sticker for signs of tampering, and review the seller's history before a high-value purchase.

No. CheckCOA is an independent verification tool. It checks provider records when available, keeps your checks across 25+ providers in one place, and adds Fraud Alert checks against known fake, stolen, reused or compromised numbers.

Yes. Every MLB Authentic 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.
