[comp.dcom.telecom] AT&T's New Calling Card

Bill Huttig <wah@zach.fit.edu> (04/14/91)

In a previous Digest someone wrote about new international calling
card numbers. AT&T has been issuing them for awhile. The US part is
not your phone number. They start with 838 or 836 followed by eleven
digits:

   the international part is 891253 83x NNN NNNN U      YY
   when the US part is              83x NNN NNNN ZZZZ

where x is a 6 or 8 and N is any number and U is a check digit (I
think same as old cards) YY has the word auth. Code above it. ZZZZ is
the normal four digit US pin.

Does anyone know when the rest of the carriers are issuing their
cards?

There is also a note on the mailer stating that to comply with
government requirements AT&T is no longer sharing card numbers with
the local telephone company.
