The situation involves infidelity where one is a close relative. The one being cheated on.

I have two phone numbers that are involved, Boston & NH area. Both numbers are involved because one is used to 'trigger' calling back from the other number. Then we have calls go on up to almost 4 hours.

I had to go back in the bills when they were sloppy. I think they use other means now.

I pay at a lookup service. It's pretty good with 'standard numbers'. One of these numbers comes up as a female with about 10 possible addresses scattered around the country. The other just says MA with no info.

Just asking if one may have some ideas??

So you have a family member who is a woman. She is married or in a committed relationship. Her partner is cheating on her with another woman. You have what you believe to be that woman's phone number. You want to use that number to figure out where the woman is located.

Does that sum up your situation?

There are several number lookup sites, but as you say they might not help much. If you really need to locate this other woman a private investigator may be your best bet. Is there a reason you need to locate her? Are you hoping to confirm the infidelity for your family member or some other purpose?

Have you tried typing the number into the internet? You can find old friends with just a name. The search often will give you a number. Maybe a number will give you a name and address. Put in as much info as you have, it will help narrow the search.

OK, got it, Now on to the next phase.

Professional private investigators have access to database services that may help answer your questions. Simple Internet search may or may not get the answer.
