UUID v4 values are extremely unlikely to collide. While no system can guarantee absolute uniqueness, UUIDs are considered safe for practical use in most applications.

Can I use UUIDs for database primary keys?

Yes. UUIDs are commonly used as database primary keys, especially in distributed systems where unique ID generation across multiple servers is required.

Is Online UUID Generator free to use?

Yes. Online UUID Generator on OnlineToolsDesk.com is completely free with no registration or usage limits.

550e8400-e29b-41d4-a716-446655440000

UUIDs are widely used to:

Determine database records uniquely.
Create API keys or request IDs.
Follow-up sessions and transactions.
Eliminate ID conflict in distributed systems.

The UUIDs are much safer as compared to the sequential numeric IDs because they are designed to be globally unique.
