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

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

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".

I just got call from this #. It isn't collector. It is really 911 center. I dial 112 because someone told me it would work for emergency in any part of the word even if I dial 112 when my phone is locked. I tested and yes it is true. If you dial 112 any time even out of your area with locked phone you get connected with 911. Cool!

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.

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.
