A GUID (UUID) is a Universally Unique identifier that is used to identify information in computer systems in a way to avoid duplicates, in most real-life situations. Is is represented by a 128-bit number
A GUID (UUID) makes replication trivial - as opposed to integers, which makes it really difficult if combining multiple database sources
It is unique across applications, in general. There is a chance of duplicates, but the chance depends on the number of records.
