Generate unique UUIDs (Universally Unique Identifiers) and GUIDs instantly with our free online tool. Supports UUID v4 (random) and UUID v1 (timestamp-based). Bulk generate multiple UUIDs at once.
A UUID is a 128-bit identifier that is unique across space and time. It is commonly used for database primary keys, session identifiers, and distributed systems.
Generate unique UUID/GUID identifiers instantly. Perfect for databases, APIs, and distributed systems.
ea8b6bac-238a-4eaf-a8a2-27ef6d31d0b7UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across space and time. UUIDs are used in databases, distributed systems, and APIs to uniquely identify resources without coordination between systems.
Random-based UUID. Most commonly used version. 122 bits of randomness provides extremely low collision probability.
Time-based UUID. Includes timestamp and MAC address. Useful when you need sortable, time-ordered identifiers.
Use as primary keys in databases for globally unique record identification.
Generate unique API keys, session tokens, and request identifiers.
Create unique file names for uploads to prevent collisions and overwriting.
