What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across space and time. UUID v4 is randomly generated, making collisions virtually impossible. UUIDs are commonly used as database primary keys, session tokens, API identifiers, and more.

UUID v4 Format

xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

Where x is a random hex digit, 4 indicates version 4, and y is one of 8, 9, a, or b.
