What can UUIDs be used for?

UUIDs are commonly used when you need a unique identifier without relying on a centralized system or incremental IDs.

Primary keys in databases, especially in distributed or replicated systems.
Public identifiers in APIs, avoiding exposure of sequential IDs.
Identifiers for files, users, sessions, orders or tokens.
Microservices, event systems and data synchronization across systems.

UUID versions explained

UUID v4 is fully random and the most commonly used. It is ideal for most applications and guarantees a very low collision risk.

UUID v7 is time-ordered, making it more efficient for modern databases and indexes while remaining globally unique.

UUID v1 is based on timestamp and machine information. It is less commonly used today due to privacy considerations.

Important note

UUID uniqueness is statistically guaranteed, not absolute. However, the probability of collision is so low that UUIDs are considered safe for real-world applications, even at very large scale.
