Reverse Phone Directory

Have you ever had a phone number you didn't have a name to, and wondered who's it was? Sometimes I've found a slip of paper or a match book with a phone number written on it, but no name. Who's number could it be? Or many different times, I've been looking at my long distance phone bill and wondered "well, who's number is that? I don't remember making a call to that number." You know you likely did, but would feel ever so much better about paying for it if you knew who you had called, then you'd know for sure you really did make that call. Well, a great thing to do in a case like this is to use a reverse phone directory to look up the number and find a name to go with it.
