Just got this call as well.. I am in Naperville and have a 630 phone number.

WTF?

Unknown and leaves no message

i just got the same thing... chicago area phone.

Just got the call on my work cell (w/ 630 area code, like others), but didnt pick it up... Was already registered on the do not call registry. Just filed a complaint.

I received a call from this number today but did not answer and nobody left a message.  I have registered my number on the do not call list....hopefully that will stop these calls!

Just received the call 11/09/2010 at 12:54p.m. CST.  I am in Springfield, IL and call is from Texas?!

Picked it up and they immediately hung up. Called it back and recorded message stated: United States Prescription Card.

I got a call as well and im in chicago area.  didnt call back though

I just got this call on my work BB. Springfield, IL

Same thing just happened to me....I just moved to Palatine, a suburb of Chicago and got this number 2 days ago and they are already calling me.....Must be something about IL...LOL

I live in TN but used to live in Joliet, I'll and still have my cell phone from there - this number shows up as unknown and I called it back and never got anyone to answer.

Just got a call from that # on my cell, which is 630 area code (Chicago suburbs). It only rang briefly and I never made it to the phone to even consider answering. I used to live in the 281 area code (Houston area) so I was suspicious!! When I called it, it said "you have reached the United States presciption card..." Bogus I'm sure. Just fishing for some telemarketers I guess.

My husband and I both got calls from this number...no one answers and no message. In IL too!

got the same call at 7:07 am!!!!!! in IL also

I live in Virginia, but I do have an 847 IL number

just got a call from this number, no VM, i am in chicago area.

Just got one from this number.  I'm in IL also.  WTF and thanks to Dj for the info.

I also live in IL and got this call, called it back and got the same US Prescription card. I have no idea what this Is.

When you call it back it says that it's the United States Prescription card. I highly doubt it. I live in IL and the number is a TX number? Wish they'd stop calling

Just get these calls now and then. No one there, simply comes up as "unknown"

Getting calls from 281-893-6121 and comes up as unknown. Who is it?

Received call from 281-893-6121  silent and then hung up.  I don't know this number.

Left a 6-second voice message on my cell phone of nothing.

Looks like someone figured out a way around the "do not call" list.  They call you and let it ring just long enough to activate your caller ID then hang up.  If you call them back, it is YOU initiating the call, not them.  That's the point of what they are doing.  Don't call the number back.  Once you do, it allows them to call you freely since you called them.  I got the call this morning and they hung up too but before I called it back I googled the number and found this website.

Had a call from them but they disconnected after 3 rings.  I guess "Do Not Call List" is not working very well.  Another government program with no teeth!!!

12/10/2010, Picked up just a minute ago and they hung up.

Just received the call 12/06/2010 at 3:30p.m. CST.  Picked it up and they immediately hung up. Called it back and recorded message stated: United States Prescription Card. I left a message telling them to remove my number from their system or be sued for harassment.

They called at 12.13pm

I rec'd 281 893 6121 - three rings and hang up. No answer - busy signal when call was returned. I see others have rec'd calls from this number too.

Called my mother's cell number at 4 a.m., not a good time for anyone to get a "hang up" call!

I don't know this number
