What is a UUID / GUID?
A UUID (Universally Unique Identifier) or GUID (Globally Unique Identifier) is a 128-bit value standardized by RFC 4122. Version 4 UUIDs are generated using pseudo-random or cryptographically strong random numbers.
Is collision possible?
The total number of possible UUID v4 values is 2^122 (approx. 5.3 × 10^36). The probability of finding a single duplicate is virtually zero, making them ideal for database primary keys, session tokens, and distributed systems.
