Frequently Asked Questions
What is a UUID?▼
A UUID (Universally Unique Identifier) is a 128-bit identifier that is practically unique. Version 4 UUIDs are randomly generated and have the format xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx.
Are UUIDs truly unique?▼
While not mathematically guaranteed, the probability of generating a duplicate UUID v4 is astronomically small - you would need to generate about 2.71 quintillion UUIDs to have a 50% chance of a collision.
