UUID / GUID Generator FAQ
What is the difference between UUID and GUID?
UUID and GUID usually refer to the same 128-bit identifier format. GUID is the term often used by Microsoft, while UUID is the standard term used in RFC 4122.
Are generated UUIDs unique?
UUID v4 values are randomly generated with an extremely low collision probability, making them suitable for distributed identifiers and database records.
Can I use generated UUIDs in production databases?
Yes, UUID v4 identifiers are widely used in production databases, APIs, message queues, and distributed systems where centralized ID generation is not desirable.
