A UUID (Universally Unique Identifier) or GUID (Globally Unique Identifier) is a 128-bit number used to identify information in computer systems. The probability of generating two identical UUIDs is so infinitesimally small that for all practical purposes, they are unique.
There are several versions of UUIDs, but Version 4 is the most popular. It is generated using random numbers. Unlike Version 1 (which uses MAC addresses and timestamps), Version 4 does not reveal any information about the computer that generated it, offering better privacy.
A standard UUID is represented as 32 hexadecimal digits, displayed in five groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters (32 alphanumeric characters and 4 hyphens).
Where"4' indicates version 4, and"y' is one of 8, 9, A, or B.
Developers use UUIDs for database primary keys and unique identifiers in API responses.
QA engineers generate bulk unique strings to populate test databases and stress test systems.
Admins assign unique Session IDs or correlation IDs to trace requests across distributed servers.
Data scientists use anonymous UUIDs to replace sensitive personal information in datasets.
