I have a new phone and the phone number seems to have been used before, by someone who wanted a notification whenever they logged in to Facebook.
Note: I do not have the phone that person had, so I can't go into the Facebook app or anything like that. I don't know their name, either.
I am getting texts at all hours of the day and night telling me "Your Facebook account was accessed from an unknown browser" etc. I want these to stop, but obviously I can't contact the person and say "you forgot to turn off your login notifications". How can I make these texts stop?

Reply with “OFF” to the Facebook texts and it should stop. More info here on this Facebook support page.
If that doesn't work, I would contact Facebook support. They are not super responsive but they can solve problems. You could also block texts from the Facebook number. This is more of the nuclear option so try to work thru Fb first. More info on how to block numbers here.
For future reference, all I did was Google "someone used my phone number for Facebook" and the Facebook support article was the top result.
Edit: As per Al E's suggestion, you could try associating your phone number with your account. I might trigger a verification process to see who has control of that number and might fix the problem.
