What does number neighbor mean?
A number neighbor is someone who has the same (cell) phone number as you, except the last digit is one lower or higher. Sharing funny or charming text-message exchanges with one’s number neighbor went viral online in August 2019.
Where does number neighbor come from?

Say your (cell) phone number is 123-456-6788. Your number neighbor, typically, would have a number ending -6787 or -6789. Number, of course, refers to phone number (usually of a cell phone), and neighbor, the idea that the two numbers are next to each, like neighbors.
An earlier version of number neighbor was text door neighbor (a pun on next-door neighbor), entered on Urban Dictionary in 2008. Sharing posts of text-message exchanges on social media got some attention in 2016.
The term number neighbor was entered on Urban Dictionary in 2009, but the trend of texting one’s number neighbor and sharing screenshots of the results went viral in early late July, early August 2019.
This happened after Twitter user @ryanlavalleee texted his number neighbor and posted the aftermath (the “neighbor” wasn’t too keen on getting to know the tweeter).
