Hi All,

I'm very curious to know if the Address Book unique record ID is guaranteed (or at least very, very likely) to be unique not only in my local Address Book database.

That is, how likely is it that two Address Book records will be created with the same ID:
- in the same Address Book database,
- on the same machine, and
- on two different machines.

I'm perfectly aware that AB is meant to be a one-user, one-machine database, but _if_ I was to move or share Address Book data between two machines, what are the chances that two records would collide?


its guaranteed to be unique. The unique Id is basically a CFUUID.

thanks for any input on this
