The online GUID / UUID Generator is used to generate random GUID / UUID.
A universally unique identifier (UUID) is a 16-byte (128-bit) number. It is an identifier standard used in software construction. The intent of UUIDs is to enable distributed systems to uniquely identify information without significant central coordination. GUID (Microsoft's globally unique identifiers) is the most widespread use of this standard.
This online UUID / GUID Generator generates version 4 (Random) UUIDs as specified in RFC 4122.
