Finding an official Certificate of Authenticity (COA) is vital when purchasing Windows 10/11 Pro or Home product activation/license keys, especially when you need to be sure that you’re purchasing a genuine product. COAs are physical or digital proof of the authenticity of software. They typically accompany retail and OEM licences. Here are 10 things to remember when dealing with COAs.
1. Find out What a COA can be.
A Certificate of Authenticity, also referred to an inscription or label verifies the authenticity of Windows keys for products. A hologram or unique alphanumeric code is often found on physical copies of the key.
It is important to know the look of the COA to establish whether the key you bought is valid. It’s typically found on the packaging of the product or, in the case of OEM versions, it’s affixed to a computer.
2. Be sure to look for Holographic and Anti copyright Features
Genuine COAs are protected by anti-copyright features such as holographic images, color-shifting ink, and fine print that make it hard to duplicate.
It is easy to spot fake COAs by examining their holographic security feature.
3. Microsoft Resources are a great tool to confirm the COA
Microsoft offers resources to help you verify the authenticity of an COA. Microsoft has provided guidelines on its site regarding the way a genuine COA should be presented, along with examples of pictures.
Be familiar with these functions to know what to look for when purchasing a product key.
4. Be wary of COAs that do not have product keys
A genuine COA for Windows always includes a unique product key. Beware of COAs with no a product code or with an unreadable key or has been altered.
The key cannot change and must be legible, clear and official.
5. Purchase from Microsoft Authorized Partners and Reputable sellers
Ensure you buy from an authorized Microsoft partners, certified sellers, or trusted electronics retailers. They will provide you with more authentic COAs and key codes for the product.
Only purchase from trusted sources. Do not buy from sellers that aren’t trustworthy or unreliable.
6. Digital Keys With No COA
An electronic COA is needed when buying a license or key. This is especially true in the case of OEM or Retail key. This is crucial when purchasing second-hand computers or refurbished ones.
If no COA or proof of authenticity is given Consider it as a red flag.
7. Check that your COA is in line with your product
The COA details should match the information on your Windows version (e.g. 32-bit, or 64-bit). The COA may contain inconsistent or incorrect information that could suggest a fake product.
When it comes to OEM licenses, the COA must also be in line with the model and the manufacturer of the device, if the device is pre-installed.
8. Don’t accept COAs that have obvious signs of damage or alteration
If you receive a physical certificate of authenticity ensure that it’s not altered or damaged. The peeling or scratch marks could be signs that the COA was copied.
A COA that is damaged may also indicate that the key has been used previously or not genuine.
9. Knowing that not all COAs are able to be transferred
OEM versions come with a COA that is tied to the original hardware. That means it can’t be transferred in the event of a PC upgrade or replacement. You should know whether the COA you’re using is for a specific device or if it’s able to be transferred.
Retail licenses are typically the only ones with a COA. This lets you be more flexible if you decide to upgrade your device.
10. Retain a Copy of the COA to be used for Future Reference
Keep a photo of a digital copy of the COA along with the product’s number for later reference. It is helpful in the event that you need to activate Windows.
If the COA is damaged or lost, you will not be able to retrieve your key.
Additional Tips
Verify serial numbers: A lot of COAs contain serial numbers you can verify this by calling the manufacturer or seller.
Keep COAs on Original Hardware. For OEM licensing, the COA should remain on the original hardware in order to maintain its validity.
Keep receipts in order: Always keep your receipts when purchasing COA-included licenses as proof of purchase.
