Looking for an official Certificate of Authenticity (COA) is crucial when buying Windows 10/11 Pro or Home product activation/license keys, especially in order to confirm that you’re getting a legitimate product.

Here are ten top strategies for handling COAs.
1. Learn about what a COA is.
A Certificate Of Authenticity also referred to a sticker or label, verifies the authenticity of Windows keys for products. For physical copies, it often includes a hologram and an unique alphanumeric product code.
Knowing what an COA is will help you determine whether the code is authentic. It’s usually located on the packaging of products or, when it comes to OEM versions attached to computers.
2. Look for Holographic Elements and Anti-copyright Features.
Genuine COAs include anti-counterfeiting measures such as holographic inks, color shifting images fine prints, and color-shifting images which are hard to reproduce.

4. Watch out for COAs without product keys
A genuine COA for Windows always includes a unique product key. COAs that do not contain the product’s unique key or have an unclear or tampered product key should be avoided.
The key cannot change and must be legible, clear, and official.
5. Buy directly from Authorized Microsoft Partners or Reputable Sellers
You should only buy through Microsoft authorized partners or certified sellers. You should also shop at reputable electronics retail stores. These sellers will offer more authentic COAs and key codes for the product.
Purchase only from trusted sources. Don’t buy from a third-party or from an untrusted source.

When you purchase an electronic key or license the seller needs to supply an electronic COA, or a proof of authenticity in particular if it’s an OEM key or retail key. This is crucial when purchasing second-hand or used computers.
It’s a huge warning sign if there is no COA (certificate of authenticity) or evidence of authenticity has been provided.
7. Make sure the COA Matches the Product
The COA’s details must be in line with the Windows version you’re purchasing (e.g. Home Pro, 32-bit, 64-bit). A copyright product could be indicated by the absence of or mismatching details.
COAs for OEMs have to match the model, brand and version of the device.
8. Beware of COAs that seem damaged or altered.
If you receive an actual COA, make sure that it’s not altered or damaged. Scratches and peeling may indicate that the device was taken from a different device or copied.
A damaged COA can also indicate that the key has already been used, or not genuine.
9. Know that not all COAs are able to be Transferrable
OEM versions are affixed to the original hardware. This means that they can’t be transferred when you upgrade or replace your PC. Make sure you know if the COA is able to be used with multiple devices.
Most retail licenses include COAs that can be transferred, making them more adaptable when you switch devices.
10. Keep a copy of your COA to be able to refer back to it in the future.
Keep a copy of your digital or physical copy of your COA and product key to use in the future. This will be useful should you have to restart Windows and verify its authenticity or contact Microsoft Support.
Store it securely to avoid losing your key in case the COA is lost or damaged.
