Is Azure client ID world wide unique?

I have a database table with Azure App registrations. These apps are added across different tenants.

I would like to know I can use the application id (client id) of Azure app as the primary key of the table.

Is the client ID world wide unique?

    Application Id (GUID) break down like this:

    • 60 bits of timestamp
    • 48 bits of computer identifier
    • 14 bits ofuniquifier
    • six bits are fixed,
