Providers from out of town, how come they have ads with Local telephone numbers in other words
you have a provider from New York visiting Los
Angeles is posting area code 323? Are telephone
numbers rented for a week or more for providers,
or Local girls are just changing their names, make up and hair color?

It could be that they are staying with a friend and are using their phone number or they may rent a phone for the short time they are here.

If they travel to a particular city frequently enough, they may keep a phone for each city to spread their minutes across different lines.

Some girls who travel frequently add the visiting tag to their ad to indicate they are back in their home town for a short time before they head back out on the road.

Some probably just add the visiting tag to give the false impression that they are available for a limited time, so go see them soon, even though they aren't going anywhere.

There are definitely a few who change their look slightly, or some not at all, and post multiple ads under different names or just with different pictures.
