The COA can be a physical certificate or a digital one that confirms the authenticity of your software. It is typically included in OEM licenses as well as retail licenses. Here are 10 important things to consider when dealing with COAs.
1. Be aware of what a COA is.
A Certificate Authenticity label sticker is a way to verify that the Windows product code is genuine. A hologram or unique alphanumeric code is typically found on physical copies of the key.
It’s crucial to be aware of the COA’s appearance in order to know if the key you bought is legal. The COA is usually on the product packaging, or, in the case of OEM models, it’s attached to the computer.
2. Look for Holographic Features and Anti-copyright Elements.
Genuine COAs are protected by anti-counterfeiting features such as the use of holographic images as well as color-shifting ink.
Look for these holographic security components that are made to aid in identifying fake COAs.
3. Verify the COA with Microsoft’s Resources
Microsoft offers resources to help verify authenticity. Microsoft has posted guidelines on its site about how a genuine COA should be presented, as well as examples of images.
Be aware of these functions so that you are aware of what to expect when you purchase the product key.
4. Caution with COAs without Product Keys
A genuine COA for Windows always includes a unique product key. COAs which do not include a unique product key or contain an unreadable or altered product key should be avoided.
The key should be in a clear, readable form, with no modifications.
5. Buy directly from Authorized Microsoft Partners or Reputable Sellers
Buy only through Microsoft authorized partners and certified sellers, or reliable electronic retailers. They are likely to provide genuine COAs in conjunction with the key.
Avoid purchasing from unknown or third-party vendors where the legitimacy of the COA cannot be guaranteed.
6. Digital Keys that Lack COA
If you’re purchasing a digital license or key, the seller should give you a digital COA, or proof of authenticity, particularly if it’s an OEM or retail key. This is especially important when purchasing second-hand or used computers.
If no copy of the COA or proof of authenticity is given If there is no proof of authenticity or COA, it could be a red flag.
7. Verify that the COA matches your product
Details on the COA must correspond to the Windows edition you’re purchasing (e.g. Home Pro 32-bit, 64-bit or Pro 32-bit). A copyright product can be indicated by mismatching or inconsistent information.
If the device comes already installed, the COA must also be in line with the model and brand of the device.
8. Avoid COAs which appear to be damaged or altered
If you get an authentic certificate in the form of a physical document, check that it’s not damaged or altered. Scratches and peeling may indicate that the device was taken from a different device or copied.
The COA can be damaged if the key is used or not genuine.
9. Some COAs aren’t transferrable.
The COA used for OEM versions is linked to the original hardware. This means it can’t be transferred when your computer is updated or changed. Find out if the COA works only for one device or if you can transfer it.
Retail licenses are usually the only ones with a COA. This allows you to be more flexible should you decide to upgrade your device.
10. Keep a copy of it for future information
Make a copy of your digital copy or a physical image of the COA along with the product’s key to be able to refer back later. This can be useful in the event, for example, you need to reactivate Windows.
Securely storing it will stop the loss of the COA should the unfortunate event that it gets damaged or stolen.
Other Tips

Maintain the COA on the original equipment: OEM licenses are valid as long as the COA is connected to the original equipment.
Keep receipts. When you buy licenses that have COAs, save your receipts as proof.
