Yes this number is from 911 operator.
Last night I accidentally called 911 last night and this number called me so I anwsered it it said "You called 911 recently " and I said it was an accident so they asked me couple questions then I was free to go. Remember don't hang up like I did when you accidentally call 911 don't hang up if you dothey will call you back and if you missed it they will send police, ambulance and firetrucks to your house.
So don't play with 911 calls

My phone is Huawei and it has dedicated button which can press itself and it is for 911. And I got a call from this number so that is definitely the 911 number.No show in call log.

This number was left on our answering machine. Due to privacy reasons, cannot return call.

Yup this is CPS, I was actually trying to call 911 today (car accident) but my silly cell kept picking up my Bluetooth in my other car LOL (I was less than a block from my house) I eventually got through ok but they had called to see why I was calling 911.

I just experienced this and I had not used my cell phone all evening. they called 2x and said it was CPS returning my phone call because I had dialed 911. Weird, maybe my phone is a defect.

Just got two calls from this number on my cell this afternoon.  It went to voice mail and a female voice said it was 911 calling - that my cell had called them and to stay on the line if I needed help.  According to my call log its total BS.  This is either a collector going to previously unheard of nastiness or a real a***ole scammer.

Same as some others -- got a call saying that I had called 911.  I thought one of my kids might have been playing with my cell & apologized. I checked the call log on my Blackberry & the most recent outgoing call I made was 6 hours ago & it certainly wasn't to 911.

Strange.  The guy was polite & didn't grill me like the reall 911 person grilled me on a previous occasion when I actually did dial 911 by mistake.  What kind of scam is this....?  When I try calling the # back after reading the posts on this page, an automated msg says "you've just dialed a number that isn't in use".
