Since I > haven't got any notification from AT&T about my Calling Card, I The difference is that the old non-subscriber cards are issued in area code 507 and 508 with a exchange that is inposible (starting with a 0 or 1) and are handled through various BOC's, I had one that was billed by Cincinatti Bell a few years ago. They provided verification for the AT&T to the LEC's. The new cards start with a 83x where x is a 6 or 8. The international part of the number is 891253 xxx xxxx xxxx x xx the 89 is the internation standard for phone card the 1 is for the North America country code. The 253 id's it as a AT&T card the xxx xxx xxxx is the same as the US version. The x xx are additional verification numbers. I was surprised that the number 253 was used as Carrier ID and not 288 like the PIC. It would have made more sense to use the PIC's. Bill [Moderator's Note: I think all the non-subscriber AT&T cards were handled by Cincinatti Bell for many years ... maybe still. PAT]
