I have gotten quite a few text from this number. Also random hours. I have called the number and I get the number did not go though. This is very upsetting when it is durning odd hours, scared that something might have happen to a love one!
If you have your Facebook set up to require a code for a login on an unrecognized device, you can ask it to call you with the code. That is this number. If you keep getting this, either someone is trying to get into your account, OR someone used your number as the contact for their Facebook. Either way - that's what this number is.
