Generate random UUIDv4 and GUID identifiers in single or batch modes.
How to Use UUID / GUID Generator
Choose how many UUIDs you want to generate at once (single or batch).
Click "Generate" to produce fresh version-4 UUIDs.
Copy a single ID or copy the whole batch list at once.
Key Features & Practical Use Cases
Generating completely unique random UUID v4 strings for database primary keys.
Creating secure, non-sequential session tokens or order tracking IDs.
Batch generating hundreds of GUIDs instantly for testing mock database structures.
Frequently Asked Questions
What UUID version does this generate?
Version 4 (random) UUIDs, the most common type for primary keys, session IDs, and general unique identifiers.
How likely are two generated UUIDs to collide?
Effectively never in practice - v4 UUIDs have 122 random bits, making accidental collisions astronomically unlikely even across billions of IDs.
Can I generate the same UUID twice on purpose?
No - each generation uses a fresh cryptographically random seed, so results are never reproducible or predictable.
