This page allows you to create a new global unique identifier or GUID. A GUID is already provided see below wich you can copy. You can use futher controls to generate or create a set of new global unique identifiers or guids. To create a new GUID please click the button below. A new GUID will be displayed on the screen. GUIDs are typically used for uniquely identifying records in programming languages such as C#, databases such as SQL Server 2008 and xml files. Technically not unique, the chances of generating the same GUID more than once is highly improbable. Thus making GUIDs very useful :)
