UUID stands for Universally Unique Identifier. A UUID is a 16-byte (128-bit) number: 32 characters (excluding hyphens) occupy only 16 bytes because each hexadecimal character needs only 4 bits (half a byte, or a nibble) to specify it. UUID is used as identifier standard used in software construction, standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE). You can easily generate UUID number online or using UUID generator tool.
