A Certificate of Authenticity (Certificate of Authenticity) is a label, sticker or other device that certifies the Windows product key. A hologram or unique alphanumeric code is often found on physical copies of the key.
Understanding the way an COA appears like will help you determine whether the key is genuine. The COA can be found on the packaging of the item, or for OEM versions, attached to the computer.
2. Look for Holographic Features and Anti-copyright Elements
Genuine COAs have anti-counterfeiting features such as holographic pictures, color-shifting pens, and fine printing, which makes it difficult to duplicate.
Look for these security elements that are holographic, which are designed to assist you in identifying copyright COAs.
3. Microsoft Resources: Verify COA
Microsoft provides resources to help you verify the authenticity of an COA. Microsoft provides guidelines on its website about what an authentic COA should look like, including example images for reference.

Be sure to purchase only from Microsoft certified partners, reputable electronics retailers, or official Microsoft partners. These sellers are likely to offer authentic COAs and product keys.

6. Digital Keys that Lack COA

7. Check that the COA is in line with the Product
The information on the COA should match the Windows edition you’re buying (e.g. Home Pro 32-bit, 64-bit or Pro 32-bit). A mismatch or inconsistent information could be a sign of a copyright item.
In the case of OEM licenses, the COA must also be in line with the model and the brand of the device, especially if the device is pre-installed.
8. Beware of COAs that have been damaged or changed
If you get an actual certificate of authenticity, check that it’s not damaged or altered. Peeling, scratches or missing pieces could mean that it has been taken or copied from another device.
The COA can be damaged if a key is misused or not authentic.
9. Know that Not All COAs are Transferrable.
OEM versions are tied to original hardware. Therefore, they cannot be transferred when you upgrade or replace your PC. Check if the COA is only applicable to one device or if you are able to transfer it.
Retail licenses only come with transferable COAs. These are more flexible, in the event you require switching devices.
10. Keep a copy of the COA for Future Reference
Save a digital image or copy of the COA with the product’s code to be able to refer back later. This is useful when you want to restart Windows or confirm the authenticity.
Store it securely to avoid losing your key in case the COA is damaged or misplaced.

Verify Serial Numbers: Some COAs have serial numbers that you can confirm with the seller or manufacturer.
