What is a UUID?
UUID (Universally Unique Identifier) v4 is a 128-bit random number formatted asxxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx. The probability of generating the same UUID twice is astronomically small — roughly 1 in 5.3×10³⁶. UUIDs are used as primary keys in databases, session IDs, correlation IDs, and anywhere a globally unique identifier is needed.
