Frequently asked questions
What is a UUID?
A universally unique identifier: a 128-bit value written as 32 hexadecimal digits in five groups. It is used to label records without a central counter.
Can two generated UUIDs be the same?
In theory yes, in practice no. A version 4 UUID has 122 random bits, so the chance of a repeat is negligible.
Is a UUID the same as a GUID?
Yes. GUID is the name Microsoft uses for the same kind of identifier.
