Your bill should list any Verizon long distance calls and charges. I assume it is a local number you are looking for. If you have on- line access, go to "My Verizon", "My Bill". On the my bill page , you should see an option called, "custom reports". When you bring up the custom reports page, you will see a list of places you called. Click on the town/city and you will see a list of the telephone numbers you called. This works in my state, hope it helps you.
