These questins came to mind during my CCNA training:
The samples in CCNA training "look" like regular telephone numbers, is that true in real life?
How unique are ISDN SPIDs?
Can there be an ISDN spid that is the same as a dial telephone?
Is there one coordinated ISDN list among all telco's, or are they "translated" between telco's?

Thsi web-page should be able to give you an idea on how the SPIDs are put together:
Cuz they are.
They are the phone numbers for each B channel with a 0101 at the end.
No.
The SPID is locally significant.
