What is UUID Generator?
Generate universally unique identifiers (UUIDs) using the secure v4 format. Use them as database primary keys, session tokens, request IDs, or any other place you need a unique string that's practically guaranteed to never repeat.
Frequently Asked Questions
A Universally Unique Identifier (UUID) is a 128-bit number used to identify information in computer systems. Version 4 UUIDs are randomly generated.
The probability of generating two identical UUID v4s is astronomically small (1 in 5.3×10³⁶). For all practical purposes, they are unique.
UUIDs are formatted as 32 hexadecimal digits displayed in five groups: 8-4-4-4-12, e.g. 550e8400-e29b-41d4-a716-446655440000.
