A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify resources in computer systems. UUIDs are generated using algorithms that ensure uniqueness without a central authority. The most common versions are UUIDv4 (random) and UUIDv7 (time-ordered). A typical UUID looks like: 550e8400-e29b-41d4-a716-446655440000.
UUIDs solve the problem of generating unique identifiers in distributed systems where a centralized ID generator is impractical. They are widely used as database primary keys, API resource identifiers, and session tokens. Unlike auto-incrementing integers, UUIDs do not leak information about record counts or creation order.
