Generate UUID (Universally Unique Identifier) instantly and for free
A UUID (Universally Unique Identifier), also known as a GUID (Globally Unique Identifier), is a 128-bit number used to identify information in computer systems. The probability of generating two identical UUIDs is virtually zero, making them perfect for creating unique identifiers.
UUIDs follow the format: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx where each 'x' is a hexadecimal digit (0-9, a-f).
This tool generates UUID v4 (random) identifiers, which use cryptographically strong random numbers and are suitable for most applications requiring unique identifiers.
