4 calls in the last two days, 2 today alone in the last 6 hours, more than 10 since getting this number in late January.  Listed as Michigan Call on my Time Warner Caller ID.  I have answered it twice, hoping to get a live person.  Just get a recording stating a number, haven't caught it it is the phone number or not, and yellow pages, then hangs up.  I have registered with the No Call Registry, but still getting the calls.  About ready to request a new number from TWC.

Well, I think I may have solved this little mystery.  I finally answered one of those "Michigan calls." Apparently, when people get new telephone numbers, they are given (sold) to whomever the entity is that distributes the Yellow Pages.  

All he wanted to know is if I received my copy of the Yellow Pages.  He seemed like a nice enough guy.  Since I answered his question, I guess I get a free two week delivery of a local newspaper.  This was a bit of a nuisance, but there turned out to be nothing sinister about it.  They didn't call tonight, so I guess that's that. I did tell him I belong to the Do Not Call Registry.

The last time these people called me was February 2nd. It was the third time they had called in just over 4 hours so I picked up. They also wanted to know weather I got my yellow pages and gave me 2 free Sunday editions to the local paper. According to the lady I should have got the first one this last Sunday but didn't. I'm not worried though because I did not give her any information but my name and adress.

just got a call from this no. in NJ. came up as ypr

I've also been getting these calls several times a day for a couple of weeks (Albany, CA).

A little googling suggests that "YPR" stands for "Yellow Pages Research", which seems to fit with some other people's experiences.

I just called the number myself (248-630-2829) and received a recording asking if I wanted to be removed from the call list. To do this I had to key in my number. I then got a message that said my number will be removed within two business days. We'll see.

Ordinarily I'd be wary of entering my number, but I figure they already have it anyway so....
