Globally unique ids (GUIDs) generator.

Online tool for generating globally unique ids (GUIDs) aka universally unique ids (UUIDs).

A GUID represents a Unique identifier - that means you cannot generate the same GUID more than once. 

A GUID has a very low (...practically impossible) probability of being duplicated. GUIDs are applied for identification purposes in a number of fields in the computer industry.

    Possible uses are (but are not limited to):
  • The identifiers in the windows registry.
  • Identifiers used in databases.
  • Identifiers used in RPC (COM, CORBA) (remote procedure calls).
  • To ensure nobody else would - by accident - provide something conflicting.

GUIDs can be generated in a number of ways but most often is a hash of several things that might be unique at any given point in time. IP address plus the clock date/time etc are used to generate Unique Ids. Each system may have slightly different algorithm to generate the Unique Id.
