Ordinarily, I don’t read those extra “informational announcements” that seem to come in every utility bill (I just stuff it back in the return envelope), but the last one I got from my phone company had some info that I’d never thought about. Even if you are on the “do not call” list or have your outgoing phone ID blocked, when you dial a toll free 800 (877, 888, etc.) number or a pay-per-call 900, 976, etc. number, your number is not blocked and can be used for telemarketing. The FCC has determined that since the cost of the 800 numbers we are calling are being paid by them that they have the right to our ID information. You can still ask the telemarketer to place you on their “do not call” list, but whether they have to comply is something I can't figure out.
