The original poster's writing was a bit vague, but I got the impression he was talking about a calling card that was actually part of his main landline phone service.
I know that some of the Bells, some of the time ... did, indeed, send over the CNID of the home telephone/account number in the Bad Old Days. But it's been a decade, or longer, since I've used or had any friends using them, so have no idea how long this lasted.
(We looked into this option about five years ago for corporate use - we wanted people to be able to call out from home or offsite or at lunch.. and have the CNID show their work number. Think, oh, a teacher or doctor calling from home. We weren't able to find anyone set up for this.)
