What is the Serial Number?

The licence key is a unique identifier that validates your software licence and confirms that your product is legitimately activated. You can find it in your purchase confirmation email, during the installation process, or in the About section of the product.

What is the Serial Number used for?

  • To verify that your Sage 50 UKI licence is valid and correctly activated.

  • To allow installation, updates, or version changes without interruptions.

  • To identify your licence or version when contacting technical support or for integrations.

  • To prevent activation errors or version conflicts.

How to find the Serial Number

  1. Open Sage 50 UKI on your computer.

  2. Go to Help → About / Product Information. You’ll see your Serial Number displayed there.

  3. If it’s not shown, check your purchase confirmation email or invoice.

  4. If you have access to the Sage portal, go to My Products, Licences, or Activation.

  5. If you still can’t find it, contact Sage UKI Support and ask for your Serial Number details.

Frequently asked questions (FAQ)

Can I use the software without knowing my Serial Number?
