A phone number was a sequence of numbers assigned to a telephone. A commercial phone number was usually advertised, whereas a private phone number was handed out between friends.
In 2286, James T. Kirk asked Gillian Taylor how he would find her, for as they said in her century (the 20th century), "I don't even have your telephone number." She said not to worry about that for, if she wanted, she would find him. (Star Trek IV: The Voyage Home)
While on a time travel mission in 1996, Tom Paris got asked his phone number by Rain Robinson. (VOY: "Future's End")
Several phone numbers seen in Star Trek begin with 555, which is a widely used prefix in fiction, selected so that real people don't accidentally end up called by fans.
