# What is the registration key and server ID?
Registration key is the unique secret combination of characters that identifies the licenses for your TrueConf Server instance. It is needed for activation of the video conferencing server after its installation. You probably received the registration key when downloading the server on the TrueConf website or when purchasing it from company partners.
When contacting TrueConf technical support, employees may request you to provide your server ID (first five characters, e.g. EB2MM) but never the entire registration key.
Two servers cannot function simultaneously on two computers with the same registration key. If you try to register two servers on different computers with the same key, a hardware key error will occur.
Server ID is the unique identifier of a TrueConf Server instance. The server identifier includes several characters that match the registration key (up to the first hyphen), for example, EB2MM. It will be displayed in the TrueConf Server control panel in the Summary section.
If you do not have a key, you can receive a free license by clicking the Download free version button on the TrueConf Server Free webpage.
A detailed comparison of the free and paid versions of TrueConf Server is available on the pricing page.
