Can you help me track down this girl I met last night.  She gave me her number, but it doesn't work

Unfortunately, tracking people down from a single number can be difficult. Your best bet would be to call the number from a blocked or anonymous number so you don't get an unknown number. You can then ask around with friends or family to try and identify who it is. From there, you can try sending a text to let her know the number is no longer in service and to get in touch with you again.
