Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is guaranteed to be unique. Version 4 UUIDs are randomly generated.
Are UUIDs truly unique?
UUID v4 uses random numbers, giving 2^122 possible values. The probability of generating a duplicate is astronomically small — effectively zero for practical purposes.
What format does the UUID use?
UUIDs follow the standard 8-4-4-4-12 hex format: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, where 4 indicates version 4 and y is 8, 9, a, or b.
