Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify records without a central registry. The v4 variant is randomly generated.
Are UUIDs truly unique?
The probability of two random v4 UUIDs being identical is astronomically small — about 1 in 5.3×10³⁶. They are safe to use as unique identifiers in practice.
