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

yes this is the cps

This number is genuinely from 911 emergency. Some cell phones do not store 911 calls in their call logs so be carefully with the emergency call buttons (i.e., blackberry lock screen)

Did you get charged

it took me a while before i figured out that by pushing any number over multiple times it goes to 911  my kids are very sneaky  on doing this

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.

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.
