You get a lot of serial numbers plus a server file when your order is processed. The server file is attached to the actual email. The rest are in the email and also can be accessed through My Account.
How can I tell my Valentina serial numbers apart?

You can tell the serial numbers apart by their prefix:

• V4RB-X. These are the Valentina DB ADK licenses. The "X" is the operating system version.
  
• VR4RB-X. These are the Valentina Reports ADK licenses. The "X" is the operating system version.
  
• VSPRO-X. This is your Valentina Studio Pro license. The "X" is the operation system version.
