A UUID (Universally Unique Identifier) is a 128-bit identifier formatted as 8-4-4-4-12 hex digits. Version 4 UUIDs are randomly generated.

Are generated UUIDs truly unique?

Version 4 UUIDs have 122 bits of randomness. The probability of collision is negligibly small for all practical purposes.

What is the difference between UUID and GUID?

GUID is Microsoft implementation of UUID. They are functionally identical and interchangeable.

Yes. Set the quantity field to generate up to 100 UUIDs at once which you can copy as a list.
