What are the advantages of unique universal identifier?
It is presumably unique across every table, every database, every server. It permits straightforward merging of records from totally different databases. It allows easy distribution of databases across multiple servers. Most replication scenarios require UUID/GUID columns.
What is the use of UUID?

What does UUID NPM do?

What is unique ID for students?

When did the Universally Unique Identifier ( GUID ) design start?

Why are unique identifiers important in a spreadsheet?
In a database or spreadsheet, unique identifiers may be designated as a specific column or field to help make sorting and filtering through information easier. This also helps trace information back to a specific user or entity within the system.
How is the Universally Unique Identifier ( UUID ) encoded?
For example, 00112233-4455-6677-8899-aabbccddeeff is encoded as the bytes 00 11 22 33 44 55 66 77 88 99 aa bb cc dd ee ff. Variant 2 UUIDs, historically used in Microsoft’s COM/OLE libraries, use a mixed-endian format, whereby the first three components of the UUID are little-endian, and the last two are big-endian.
