ACOA Lookup: Verify an AutographCOA Certificate Number
Verify an AutographCOA (ACOA) certificate number in seconds. AutographCOA, known as ACOA, is a third-party autograph authentication company founded in 2018 by lifelong collector Justin Steffman, and its Certificates of Authenticity carry a unique certificate number in a two-letter, five-digit format (for example SA12345). Enter that number to confirm the signature ACOA examined, then screen it against our Fraud Base of known fake, stolen, reused or compromised numbers, with 25+ authentication providers supported. CheckCOA is independent and not the official AutographCOA site.
Checking more than ACOA? CheckCOA also verifies PSA/DNA, Beckett BAS, JSA, Fanatics, Panini, SGC Authentic and 20+ more autograph providers in one place.
Enter the AutographCOA (ACOA) certificate number printed on the COA - two letters followed by five digits (e.g. SA12345). Scan the QR, upload a photo or type it in.

How to read your ACOA certificate number
Every AutographCOA COA has a unique certificate number in a fixed format: two letters followed by five digits, for example SA12345. The same number is printed on the item's ACOA sticker and on the certificate, and the two should match. Enter the number exactly as shown to pull up the signature ACOA examined.
Find the number
Look for the two-letter, five-digit code (e.g. SA12345) on the COA and the matching ACOA sticker on the item.
Match the sticker
The number on the item sticker and the COA should be identical. If they differ, review the listing carefully.
Enter it exactly
Type all seven characters as printed, or scan or upload a photo and let OCR read them.
Is AutographCOA (ACOA) legit?
Yes. AutographCOA is an established third-party authenticator run by lead authenticator Justin Steffman, who has decades of hands-on experience and has been featured in mainstream media, including a Paul McCartney tour documentary. ACOA COAs are widely used by collectors and marketplaces. As with any authenticator, a COA is an expert opinion, not an absolute guarantee, and a real certificate number can be copied onto a different item, so still compare the signature, item and photos before buying.
ACOA lookup plus extra fraud protection
A standard ACOA lookup can help confirm the signature and item behind a certificate number. CheckCOA brings that into an all-in-one verification workflow and adds a safety layer: Fraud Alert checks against known fake COAs, copied certificate numbers, reused numbers and compromised records.

CheckCOA

Fraud Alert protection and ACOA red flags
A real ACOA certificate number can be copied onto a different item, and counterfeit COAs and stickers appear on marketplaces. CheckCOA screens every ACOA lookup against a growing database of known fake, stolen, reused and compromised certificate numbers to help reduce that risk.
- The number on the sticker does not match the COA
- The certificate number is not two letters plus five digits
- The same certificate number appears on multiple listings
- The signature or item does not match the COA image
- The sticker or COA looks altered, blurry or reprinted
- The seller avoids clear close-up photos
- The price is unusually low for a high-value signature
A clean result is not a guarantee of authenticity. New fakes appear every day, so always compare the signature, COA, item photos and seller history before buying.

Yes. AutographCOA is an established third-party autograph authenticator founded in 2018 by Justin Steffman, a longtime collector and lead authenticator. ACOA COAs are widely used by collectors and marketplaces. As with any authenticator, a COA is an expert opinion rather than an absolute guarantee, so still compare the signature, item and photos before buying.
What does an ACOA certificate number look like?
An AutographCOA certificate number is two letters followed by five digits, for example SA12345. The same number appears on the COA and on the item sticker, and the two should match.
Where do I find the ACOA number?

Can I look up an ACOA COA number online?
Yes. Enter the two-letter, five-digit certificate number to check the AutographCOA record when available and screen it against Fraud Alerts. CheckCOA supports QR scan, camera scan, image OCR and manual entry.
Why would an ACOA lookup show no results?
It can be a typo, a number that is not two letters plus five digits, or a record that is not available from the provider source. A no-result does not automatically mean the item is fake, but review the COA, sticker and photos more carefully.
Can a real ACOA number be used on a fake item?
Yes. A genuine certificate number can be copied onto a different item, so compare the lookup result with the actual signature, COA image, sticker and seller photos before buying.
Is CheckCOA the official AutographCOA lookup?
No. CheckCOA is an independent verification tool. It helps you check provider records when available, organizes your checks in one place, and adds Fraud Alert checks against known fake, stolen, reused or compromised numbers.
How do I get a COA for an autograph?
Submit the signed item to an authentication company such as AutographCOA for examination. If the experts consider it genuine, they issue a Certificate of Authenticity with a unique certificate number, which you can then verify here before reselling.
Can CheckCOA help spot fake or reused ACOA certificates?
Yes. Every ACOA 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.
