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

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.

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

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)

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.

yes this is the cps

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.
